Kepler 's Laws Of Planetary Motion
Kepler's Laws of Planetary Motion Johannes Kepler was a German mathematician and astronomer.
Best known for his laws of planetary motion, Kepler was a key figure in the scientific revolution in
the 17th century. His laws illustrate the fundamental properties of the orbits of the planets and were
also a precursor to the formulation of Newton's law of gravitation. Biography: Kepler was
introduced to astronomy in his early years and developed a passion for it, which would span his
entire life. At age six, he observed the Great Comet of 1577. At age nine, he observed another
astronomical event, a lunar eclipse in 1580. While in school, Kepler had proven to be an excellent
mathematician and earned a reputation as a skillful astrologer, being able to cast horoscopes for
fellow students. He also learnt both the Ptolemaic system and the Copernican system of planetary
motion and, similar to Copernicus, believed that the sun was the centre of the solar system. He
became a mathematics and astronomy teacher at a school in Graz, despite his desire to become a
minister, but soon left to Prague and met Tycho Brahe. Tycho Brahe: Brahe, from a rich Danish
noble family, was fascinated by the vast solar system and the universe. Disappointed with the
accuracy of the data for the motions of the planets at the time, he decided to dedicate his life and
resources to recording planetary positions, which proved to be far more accurate than the best
previous work. After some early successes, and

The Effect Of Friction On The Coefficient Of Friction
Introduction:
When two objects get in contact with each other the force between them forms. Scientists call this
force the frictional resistance, or friction. It occurs because of the imperfections in the surfaces of
objects, the molecules of both surfaces interfere with each other creating a natural force between
two objects. The friction opposes direction of motion of the object and is parallel to the surface on
which the action takes place. The force and magnitude that are necessary to overcome friction can
be calculated. Area of objects that is involved in the contact is disregarded when calculating friction.
Objectives:
 Use two methods to find the coefficient of friction.
 Identify factors that have influence on the coefficient ... Show more content on Helpwriting.net ...
The benefit that machine provides is called a mechanical advantage. Its amount is defined by actual
mechanical advantage (AMA, includes force of friction). There is also an ideal mechanical
advantage (IMA) but it does not take in account the force of friction which is inevitable in our
world.
Workinput=Workoutput+Workfriction
AMA=Resistance/Effort=Fr/¬Fe
Where Fr is resistance and Fe is effort.
A person gains mechanical advantage from using the machine if the effort he has to exert is less than
resistance.
IMA=Effort Distance/Resistance Distance = De/Dr
Efficiency of the machine is determined by the following formula: Eff=AMA/IMA*100

from Virginia Woolf's famed diary by American composer Dominick Argento. Each of the eight
diary excerpts is presented chronologically as its own musical movement. The selected entires range
from Woolf's first entry (April 1919) to Woolf's last entry (March 1941). The diary text is brought to
life through Argento's highly annotated musical setting. The score is written using a twelve–tone

This theme is made up of four sustained bell–like tones that create a pair of major sixth intervals.
The major sixth intervals are separated by a whole step and are first ascending following by

the movement down an octave in the alto part. The bass of the piano calmly arpeggiates a G Major
triad. FIGURE 3: "The Diary", measures thirteen to fourteen At measure thirty–one, the C section of
the rondo begins with a calming and reoccurring E Major chord pedal point. The vocal line quotes
the interval of a major sixth from the "arching half note theme", unifying the B and C section. A
brief rhythmic quoting of the opening anacrusis also occurs, but for the first time as a major second

Carl Friedrich Zelter, the conductor of the Berlin Singakademie was another primary character in
the 19th century revival of Bach's vocal music. He performed some of Bach's motets and showed
Bach's music to many of his colleagues and students. Zelter exposed Eduard Devrient and
Mendelsshon to the St. Matthew Passion and allowed Mendelssohn to conduct it in 1829. (Arnold,
Bach, 89–90.) This time the audience reacted very well, in terms of the music and its religious
significance. Reports of the perfoamcne circulated throughout Germany. This began to transform the
revival from a cult to a popular movement. The St. Matthew Passion was produced in many German
towns in the early 1830s. Then performed by the Berlin Singakademie in 1833 and the ... Show

Freezing Point Depression
Introduction:
The purpose of this lab experiment is to calculate the change in the freezing point of cyclohexanol
and a solution made with cyclohexanol to find the molar mass of the unknown solute. The
colligative properties of solutions are based on the concentration of molecules rather than the
identity of the chemical. Freezing point, a colligative property of a solution, is constant in any
substance and does not rely on the amount given. For any solution composted of two or more
components, there is one solvent and one or more solutes. The major amount is the solvent and the
minor amounts are the solutes. When solutes are dissolved in solvents, the solution's freezing point
is ... Show more content on Helpwriting.net ...
This can be accounted for in the sample of cyclohexanol. The experiment must have had a
contaminated sample of cyclohexanol, rather than a pure sample. This accounts for the difference in
the experimental values and the actual values.
Conclusion:
By demonstrating the application of a colligative property of a solution, the change in freezing point
observed between the cyclohexanol and the solution with the cyclohexanol as the solvent can be
used to calculate the unknown solute's molar mass. The data in the lab was graphed and shown in
the cooling curve. Bases off the data on the graph, the freezing points are shown where the
temperature remains constant. Using the freezing points, the difference of freezing point was
calculated. The molality of solution was calculated in the lab using the molar mass of the unknown
solution from the given previous data. The data in the lab showed the molar mass of the unknown
solute to be off from the given molar mass in the lab. This can be explained through contamination.
Theoretically, it was learned that by calculating the freezing point of an unknown substance, it can
be identified. The lab showed important techniques in using a graph

Each crucible was a different weight, size and a slightly different shape. Also the amount of
substance measured into them was also a crude approximation on its own. This meant that each time
a sample was heated the rate of the evaporation happened at a completely different rate which could
have attributed the yield of a range of different results. Also when taking into consideration the
aforementioned minor residue of water after heating a greater uncertainty is created where one is
unable to account for the percentage that this water makes up. Furthermore with the different
quantities of substance in each trial that percentage manifests itself as different quantities which
affect the uncertainty to different degrees. Therefore if time allows for the experimenter it would be
suggested to use the same crucible and lid for each trial, thoroughly cleaning and drying it between
trials. It would also be suggested to use the same amount of substance for each

The Iconic Lives of Johann Sebastian Bach and Ludwig van...
In this essay I will be talking about two of the most iconic musicians of their times and even today.
Johann Sebastian Bach from the Baroque era and Ludwig van Beethoven from the classical era.
Both of those musicians were a great influences to our music culture today. Here I will try to
compare their musical lives and talk about each of the musicians. I will look into their works and
compare their styles, rhythm, texture, form, melodic contour, harmonic orientation and the time of
each composition. We will look into live styles, music background and major contributions of
Johann Bach and Ludwig Beethoven.
Johann Sebastian Bach was born on March 21st, 1685 in in Eisenach, Thuringia, Germany. He was
from a family of musicians and learned to play the harpsichord, violin and the organ. Bach was
given a religious education and it affected his life, he was profoundly religious. He first job was a
court musician, he worked different positions as an organist which allowed him to write church
cantatas. He wrote a number of famous works the Toccata and Fugue in D minor, The Well–
Tempered Clavier and Mass in B Minor. In 1723 he was given a position where he can both teach
and create church music. In 1733 Bach created Mass in B Minor that got him a position as a royal
court composer to the King of Poland. Bach created The Art of Fugue in 1749 and on July 28 in
1749 he passed away after having a stroke. He is known to be a composer that can put notes
together like no one else.

He composed many keyboard pieces for his earlier compositions and as he aged moved on to
writing more solemn and austere pieces, many for woodwind. The Trois Novelettes are three short
pieces composed for solo piano. The third novelette was written in 1959 and was later added. The

first novelette, in C major, is an example of his illustrative multi–layered piano writing. This was
composed in 1927. With the charming melody, this piece is tuneful and song –like. The piece has
many sections, each with a different texture . The style is very dreamy. This feeling can be brought
out with the fuzzy pedalling and the melody ringing out on top. The second novelette, in B flat
minor, is very rhythmic and playful, similar to the style of a Scherzo. It was composed a year after
the first. There are many chords and accented notes, with a contrast of the melodic slurred notes and
jumpy staccato notes.

helped discover density whilst unknowingly using the displacement method. –
Density is the mass and volume of substances which is different in the 3 states of matter. The
density of the 3 matters can often be affiliated with the amount of space in–between the particles. In
the matter gas particles are quite spread out so they have a low density whether as in the matter
Solid particles are tightly packed together and have a higher density.
Density is often used when comparing the heaviness of two objects.

Christian Music Vs. Secular Music
While gazing at a statue of Isaac Watt in Westminster Abbey, the great English poet Victor
Longfellow once quipped, "He only did better what no man has ever done well!" Professor Edward
B. Reed voiced a similar opinion, "In this great mass of poetry (hymnody) there is little that shows
artistic excellence."
Both men were correct. In terms of artistic merit, Christian hymnody pales greatly in quality in
comparison to secular music. The reason for such a disparity is simple: the world's best composers,
musicians, and songwriters do not work for the church; they work in the secular music industry.
How then, do the local churches, especially smaller parishes, achieve excellence regarding music in
liturgy? In a word, they do not because they cannot. ... Show more content on Helpwriting.net ...
In other words, in order for the masses to accept it, contemporary forms of music must sound
contemporary to the modern ear. To achieve a high degree of authenticity, modern church music
must be played on modern instrumentation by musicians who possess specific experience and
particular knowledge and the appropriate training. The modern mission constituency is too
sophisticated to tolerate and accept watered down renditions of rock, country, folk, or blues music
played on pipe organs by classically trained pipe organists who noticeably misunderstand and
disrespect the subtleties inherent in 21st Century music. At best, they merely retool modern genres
to suit and satisfy classical palates.
J. S. Bach's B Minor Mass with its great chorale fugues, elaborately ornamented arias, and
orchestral accompaniment, may very well be the greatest chorale work ever composed; however,
liturgical music is ill conceived as a great art form. Accessibility is paramount and, at its finest,
liturgical music remains natural, unpretentious, and

Johann Sebastian Bach Speech
Johann Sebastian Bach was born on 21 March 1685 in Eisenach, duchy of Saxe–Eisenach (modern–
day Germany). Bach was the youngest of 8 children. He was born into a family that consisted of
many professional musicians, including Johann Ludwig Bach, another well–known composer.
Sebastian Bach's father, Johann Ambrosius Bach worked as a town musician and it is believed that
Ambrosius taught him the violin and basic music theory. By the age of 10, both of his parents had
died and Sebastian had begun living with his oldest brother Johann Christoph Bach who was an
organist at St. Michael's Church. While living with his brother, Sebastian studied and performed
music while being taught the clavichord. Throughout the five years he spent with his brother,
Sebastian Bach was introduced to the works of many German, French and Italian composers. By
April 3, 1700, Sebastian Bach enrolled in St. Michaels School in Luneburg. Bach had a soprano
singing voice and was a part of the school's choir. During his time at the school however, his voice
changed and eventually he switched to playing the violin and harpsichord. He was greatly
influenced by his organ teacher George Bohm and from watching performances by German organist
Johann Adam Reincken. Bach graduated from St. Michael's School in January 1703. He was later
appointed to be the musician for the chapel of Duke Johann Ernst III in Weimar. There he served as
a violinist and occasionally filled in as the official organist. His seven months

The rhythm of this section also lends a sense of sincerity and anxiety to the words "Christ, have
mercy," while the ascending entrances (tenor, bass, alto, soprano) in measures 73–77 intensify the
emotional impact.
"Christe eleison" begins in the key of G minor, the subdominant minor of the principal key of the
work (D major), but moves through B–flat and B minor before ending on the dominant of D major.
The first fourteen measures are assigned for soloists.
In measures 78–80, Dvořák appears to be preparing to end the section, but when the soprano comes
in with the ascending sequences in measures 81–85, the mood is brought to the climax of the

Influence of Baroque Music to Classical Music
CHAPTER I INTRODUCTION Music of any period reflects, in its own way, some of the same
influences, tendencies, and generative impulses that are found in the other arts of that time (Donna,
2005). Thus the word "baroque," usually used despairingly by eighteenth–century art critics to
describe the art and architecture of the seventeenth and early eighteenth centuries, came to be
applied also to the music of the seventeenth and early eighteenth centuries. After some years after
the death of Johann Sebastian Bach, the ornate, formal and strict form of the High Baroque became
"old–fashion" and lost its favor. Music slowly began to change form the style and forms of the High
Baroque to a simpler yet tuneful form around 1750. The period ... Show more content on

This group of individuals is known as the Florentine Camerata, they wanted lines to be sung instead
of simply being spoken (Styles of the Baroque Period). The group developed a new vocal style
based on the music of the ancient Greek tragedy. This new style followed the rhythms and pitch
fluctuations of speech. It was sung by a soloist with only a simple chordal accompaniment and was,
thus, homophonic; the Camerata rejected polyphony because it would obscure the all–important text
(Kamien, 2008). Together with the opera, the oratorio stands as a major development in baroque
vocal music. Like opera, the oratorio is a large–scale composition for chorus, vocal soloists, and
orchestra usually performed during the Lenten season in the oratory, from which its name was
derived; it is usually set to a narrative text. Oratorio differs from opera in that it has no acting,

Johann Sebastian Bach: One Of The Greatest Western...
Johann Sebastian Bach is now considered one of the greatest western composers of all time. Bach
was born on March 31, 1685 (N.S.), in Eisenach, Thuringia, Germany. He had many positions as an
organist during the early 18th century, creating famous compositions like "Toccata and Fugue in D
minor." At a young age, Johann Bach was taught by his father to play the violin and the harpsichord
in there own spacious home. Bach was a good learner, and student. His famous uncle Johann
Christoph Bach was organist at the Georgenkirche in Eisenach, and later taught him to play the
organ, and that's where it all started. Not only was Bach a good learner, he was also a great teacher.
Bach taught each of his five sons music and they all became successful

Johann Sebastian Bach Research Paper
Johann Sebastian Bach is known as the most influential organists of all time. More so, he is
considered one of the greatest composers in music history. Born into a family of musicians, he was
instructed by his father, Johann Ambrosius, who worked as a musician in Eisenach. Bach already
had the thriving urge to take on various musical positions. His family of musicians stretches back as
far as seven generations. Johann was born on March 31, 1685 in Eisenach, Germany. Some of his
best known compositions are "Mass in B minor" and "The Well–Tempered Clavier".
At age seven, Bach attended school where he gained religious instruction and studied various
subjects, such as Latin. However, Bach's Lutheran faith subjective his work as a musician. By ...

Bach's reputation was growing. He was a great performer. Another job he had was as an organist at
the New Church in Arnstadt. His main contributions was as a musical instruction and performer of
religious music for church services. At times Bach could be a conceited man. He didn't cooperate
well with his students. Church officials had reprimanded him for not rehearsing them often. While
on leave from the church for a couple of weeks. Bach went to Lubeck to visit famed Dietrich
Buxtehude. However, he extended his visit for seven months. Eventually, no one heard from him
and that didn't help the situation he was in. Awoken with joy, Bach received a new position as an
organist in Muhlhausen at the Church of St. Blaise. The joy quickly ended with his new job because
the pastor of the church wasn't in favor of Bach's playing style. His musical style during this time
was bursting with complex arrangements incorporating different lines of melody. Like most church
music in this period, the pastor preferred the music to be simple and delicate. Two of his famous
pieces during this time is the "Acut Tragicus". After spending a year in Muhlhausem, he won the
organist spot at the court of Duke Wilhelm Ernst in Weimar. While working for the duke, he
composed some of his best compositions. Some of his works included the "Fugue in D minor" and
"Heart and Mouth and Deed". In 1717, Bach was offered a new position with Prince Leopold.
However, he was imprisoned for about two months by Duke Wilhelm Ernst because he didn't have a
reason to let him go. Finally in December of the year, Bach was released and continued on at

Differences Between Mass And Projected Area And Mass Of...
The last nine experiments listed in Table 1 have reported the projected area and mass of the
firebrands. Fig. 3 depicts the PDF and contour plots for OWB7. Figs. 3a and b, represent the PDF
for the firebrands at 4 meter and 18 meters from the fire front respectively. Considering Fig. 3c, we
can realize that the correlation between mass and projected area of firebrand is stronger than
projected area and the traveling distance of the brands. This fact is more obvious at closer distances.
Moreover, the analysis of results of this experiment shows that larger brands can fly further away
from the fire which sometimes is not in agreement with other experiments. The available data at 4
meter and 18 meter from the fire has been compared in Fig. 3d. We can observe that heavier brands
could travel further with the wind. In addition, it is understandable that the mean and standard
deviation values for mass and area of the firebrands at further distances are larger which means that
we have more variety of sizes there.
The PDF and contour plots for IWB1 are plotted in Fig. 4 and Fig.4a shows the PDF for both dry
and wet trays. Since we did not have access to individual brand information, using the presented
table in their paper, Table 7 here, we assume the average value of area for each category and for
S>4, we assumed the brand area is 5 cm2. The number of the brands in the wet tray is greater than
that of the dry tray since many brands have blown away from the dry tray and burned out

Johann Sebastian Bach was well known as a performer as well as composer of keyboard music. As a
testament to Bach's virtuosity Phillip Spitta wrote "friends and foes alike bowed to the irresistible
force of an unheard–of power of execution and could hardly comprehend how he could twist his
fingers and his feet so wonderfully and so nimbly without hitting a single false note." (J.S. Bach,"
Great Composers 1300–1900). However, his vocal compositions were predominately ignored until
the flowering of the Bach Revival in 19th century. In addition during his lifetime, many people
agreed with Johann Adolph Scheibe's opinion that Bach's vocal compositions "depreived them of

Comparing Notre Dame Mass And The Kyrie Of Palestrina's
"Agnus Dei" of Guillaume Machaut's Notre Dame Mass and the "Kyrie" of Palestrina's Pope
Marcellus Mass is similar in that both have a polyphonic texture throughout the piece. The pieces
have three different sections that repeat the same text. Both pieces also call forth the spirit of a
Gregorian Chant. Not only are they polyphonic, but also they are part of the five sung prayers of the
Ordinary Mass. Both pieces have inspired some of the greatest chorale work.
Machaut composed his piece during the mid–fourteenth century and it is one of the most well

In the recording used, the mass is performed by the Hilliard Ensemble, using six unaccompanied
male voices. Agnus Dei is a solemn and elaborate piece that is in triple meter. In the mass, two
lower voices, one being a tenor, sing a theme based upon a rhythmically altered Gregorian Chant,
known as cantus firmus. While the two lower voices sing a cantus firmus, the upper voice parts are
rhythmically active and use syncopation. These four parts create complex rhythmic patterns that
contribute to its intensity. The harmonies of Machaut's piece contain dissonances, hollowing
sounding chords and full triads. Mchaut uses musical elements in his performances like
syncopation, dissonance and church modes. Church Modes consist of seven different tones and an
eight tone that dupicates the first an octave higher. The patterns of whole and half steps in church
modes are different from those of major and minor scales. The mass is in three sections, and in each
section, the same text appears. The text is only different when miserere nobis changes to dona nobis
pacem in the third section of the mass. Section A and B are alike in mood, rhythm, and texture and
end with a hollow–sounding

Essay On The Baroque Era
The Baroque era existed between 1600–1750, it was an era of freedom in composition,
improvisation, drama and urgency which was present in many aspects throughout the era.Historical
event took place, such as the thirty year war which occurred between the years 1618–1648, the
discovery of New York by Henry Hudson in 1626, building of St. Peter's square in 1656 and the
ruling of different kings in this time period. Through the work of Bach,Vivaldi and Handel, the
Roman Catholic Church, dramatic aspects and writing for royalty are ideas and influences that make
this era distinct from other eras.
The Roman Catholic Church played a major influence on the music played and composed, this is
specifically shown in the works of Johann Sebastian Bach. Bach was born on March 31, 1685 and is
a major composer associated with the Baroque era, he was an organist and composer that worked in
different churches. His later works in leipzig revolved around the church and creating musical
interpretations of the bible. The St. Matthew's passion written in 1727– 1729 by Bach portrays the
story from Matthew's gospel about the ... Show more content on Helpwriting.net ...
Antonio Vivaldi, born in 1678 was a composer who was successful and known for his concertos.
The Four Seasons, written in 1720 by Vivaldi is a concerto which consisted of alternation between a
solo instrument and the orchestra, this created a dramatic sound within the music because of the
tension build up between the soloist and the orchestra. Dramatic aspects are also shown through
another one of Vivaldi's concertos called Concerto for Two Trumpets, this also featured alternation
between soloist and the rest of the orchestra. The soloists were trumpets where they were showcased
in the piece. Through the works of Vivaldi it is shown that baroque composers used drama to make
their pieces more

Influence of Baroque Music to Classical Music
CHAPTER I
INTRODUCTION
Music of any period reflects, in its own way, some of the same influences, tendencies, and
generative impulses that are found in the other arts of that time (Donna, 2005). Thus the word
"baroque," usually used despairingly by eighteenth–century art critics to describe the art and
architecture of the seventeenth and early eighteenth centuries, came to be applied also to the music
of the seventeenth and early eighteenth centuries. After some years after the death of Johann
Sebastian Bach, the ornate, formal and strict form of the High Baroque became "old–fashion" and
lost its favor. Music slowly began to change form the style and forms of the High Baroque to a
simpler yet tuneful form around 1750. The period ... Show more content on Helpwriting.net ...
New forms of polyphonic music were developing because baroque composers felt that the art of
counterpoint was essential to their artistry.
On the other hand, the homophonic method (a musical technique that displays a vast separation
amongst the melody line and the accompaniment) was gaining acceptance and use quite rapidly
(The Baroque Era). The homophonic musical style played a significant role in opera and solo vocal
music because it focused the listener's concentration in the poetic melody of the singer.
Most pieces in baroque music have the basso continuo which gave way to uniformity and unity.
Basso continuo, or figured bass, is an accompaniment which consists of a bass part with numbers
which specify the chords to be played above it. Musical works containing a continuo part helped to
convey harmonic support of chords under the melodic line (The Baroque Era). Kamien (2008) states
that basso continuo is usually played by at least two instruments: an organ or harpsichord and low
melodic instrument like the cello or bassoon.
Kamien (2008) also adds that "the organist of harpsichordist plays the bass part with the left hand
which is also played by the cellist or bassoonist. With the right hand, the keyboard player
improvises chords or melodic line by following the numbers. Because the numbers only indicate a
basic chord, the performer has a wide field of freedom."
With continuity of rhythm and melody, baroque music also features continuity of dynamic level.

The fugue during the baroque era and in B Minor Bass consisted of soprano, alto, tenor, and bass
each of which were sung and performed in this orchestra production. Essentially each piece begins
and ends with paired choruses, indicating tender arias in each movement. Each movement
throughout Bach– B Minor Mass symbolizes spiritual convictions and during this era religion was
very important. The performance was very well developed and conducted in my opinion. As I
continued to listen to each piece and watch each performance I identified the meaning behind music
in the baroque era. Each choral and instrumental section was split into distinct parts of the stage,
allowing the best implicated sound to be conducted in the orchestra. When listening to each
movement of Bach's orchestral art it is heard to be simplistic but unique which catches the attention
of all listeners. Due to this music being closely related to religion all the religious people of this era
and of today adore the improvising of Bach not only in B Minor Mass but also in a variety of his
other musical movements. In all, the description of this performance was a creative musical

Abstract:
The experiment was done to investigate the shear force and bending moment in a beam. A shear
force in a beam experimental frame and a bending moment of a beam experimental frame was used
along with the digital force display unit to conduct the experiment. When the force increases with
constant distance from the cut, the shear force and bending moment would increase. In the second
experiment, the load is placed at a specific distance to the left of support A. The shear force and
bending moment is than obtained and calculated using the formula that had been given in the
handout.

method for determining the center of mass of each state is split up into five steps. The first two, file
conversion and sorting, gave a huge amount of raw data, and then condensed it into a workable
form. The third step converted latitude and longitude coordinates into kilometers. The fourth step
took the trapezoids formed by the previous steps and calculated their moments with respect to the x
and y axis's. Finally, the conversions were reversed to give the center of mass. All of the states were
downloaded as shapefiles from the National Boundary Dataset maintained by the USGS. Then then
the .shp files were converted to .kmz with ArcMap10.4, and then converted to .kml with Google
Earth. Then the approximately 30,000 latitude and longitude coordinates for each state were saved
as a .txt file and imported into Excel. The shapefiles gave a coordinate approximately every 400

Potassium And Sodium Lab Report
Is Potassium or Sodium in our Bicarbonate
Introduction
A mix–up at a local distribution company has occurred and the company needs assistance in
determining which bicarbonate contains potassium and which possess sodium. Due to the uniquely
opposite reactant properties each element contains, it is essential to determine and be positive of
which bicarbonate is which. Three possible chemical reactions occur during the thermal
decomposition of either bicarbonate. We are to use the predicted product masses of those reactions
to determine if it has potassium or sodium, along with a flame test.
Procedure
Experiment 1
To start this experiment, I began by first creating the three different chemical reactions that could
occur as a decomposition of the bicarbonates. Once these were made and I had the predicted mass of
each reaction, I gathered the essential materials that I would need. These included a plastic boat, a
scale, two crucibles, a Bunsen Burner, and metal tongs, and a sample of each carbonate that was
labeled "A and B." Upon getting these supplies together, I measured out 2.5 grams of the unknown
bicarbonate A. Before doing anything else, I made sure to measure out the crucible to help me
determine the mass of the reactant. After this was measured and recorded, I put the 2.5 grams of
substance A in the crucible and placed is over the Bunsen Burner. I turned the burner on and
adjusted the flame until the blue cone was just below the crucible. Once the burner was adjusted
appropriately, I left the crucible on the Bunsen Burner for approximately 15 minutes. After 15
minutes passed, I used the metal tongs to take the crucible off the Bunsen Burner and allowed it
time to cool. As the crucible with substance A in it cooled off, I got bicarbonate B and used the
plastic boat to collect and measure 2.5 grams of it. Then, I grabbed my second crucible and
measured the mass of it using my scale. After that, I placed the 2.5 grams of bicarbonate B in my
crucible and put it over the Bunsen Burner, adjusting the flame as I did with my prior bicarbonate.
As I allowed my second substance to set above the flame for 15 minutes, I made sure my first
crucibles, with bicarbonate A, was cool enough to be weighed. Seeing that

A Look At The Sound Of Music
A Look at the Sound of Music As a college student, I have seen innumerable people walking by
with their headphones in, using music to block out the rest of the world. With the convenience of an
iPhone or other smart phone, listening to music has become so casual. With the press of a button,
voila! Miley Cyrus is at the tips of your fingertips. It's become so normalized that these same people
seldom think about the science behind that noise in your ear. A disturbance in space results in a
periodic wave which propagates through that space, usually transferring energy ("Introduction to
Waves"). This transfer of energy can be explained by the conservation of momentum and energy in
collisions. Momentum is never lost; kinetic energy may be lost. If kinetic energy is conserved, the
collision was elastic; if the kinetic energy was transferred, the collision was inelastic.
Momentum is a vector, defined as p=mv, where momentum equals mass times the velocity at which
the mass travels. The rate of change of momentum is that mass's net force, defined as ∑▒〖F=∆p/
∆t〗, where force is equal to change in momentum over a given time interval ("Lecture 12:
Momentum").
Mechanical energy is equal to the sum of kinetic (KE) and potential energy (PE), derived from the
law of conservation of energy, which states that the total energy of a closed system is conserved
(Tuckerman). Potential energy is energy that is associated with some force, and is thus dependent on
its initial position. Potential
