Rate Of Reaction Carbon Dioxide

... onward sources, from a textbook, encyclopedia,
and preliminary work that I have done in class. I
have shown my results on a bar chart and a line
graph. On the line graph, I have drawn a curve of
best-fit. There were no anomalous results. From my
results, and my graph, I have found out that as
the temperature of the enzymes (yeast in this
case) is increased, the rate of reaction speeds
up. However, when the temperature reached a
certain point, (about 40 degrees Celsius), the
enzymes became de...

Thyroid Gland Pituitary Gland
1,366 words
According to the American Thyroid Association,
millions of Americans (especially women) suffer
from a thyroid disorder, and many of them dont
even know it. In fact, thyroid disorders occur
much more often than even many doctors realize.
The butterfly-shaped thyroid is in the neck, its
two wings wrapped around the windpipe just below
the Adams apple. This vitally important gland
normally weighs less than an ounce, but it can
have an enormous impact on your health. Think of
it as your bodys metabo...

Valence Electrons Carbon Dioxide
328 words
For my report, I choose to design a ball and stick
model for a carbon dioxide molecule. I used the C
as the center and an O on each side of the C. For
Christmas purposes I colored the C green and the
two Os red. To make the letters, I used white out.
The sticks that connect the balls are actually cue
tips that I have taken the cotton off of. I used
glue to make it stick on better and just punched
in the stick. The sticks are suppose to be springs
and I tried bendable straws that were cut, but
th...

Positive And Negative Conduct Electricity
595 words
Electrolytes are liquids that conduct electricity.
Most need to be dissolved into water or another
solvent. Battery's have an electrolyte in them,
either as a liquid or as a paste. Liquid
electrolytes are used in electrolysis,
electroplating, and other chemical processes. When
electrolytes dissolve they release positive and
negative ions. The released ions carry electric
charges between electrodes, in the solution.
Cations (a positively charged ion that migrates to
the cathode, a negative electr...

Acetic Acid H 3
842 words
In the simple formalism proposed independently by
Bronsted and Lowry in 1923, an acid was defined as
a proton donor and a base was defined as a proton
acceptor. In the simple acid-base reaction shown
below, H 3 O+ is termed a Bronsted Acid, and HO- a
Bronsted Base. In writing organic reaction
mechanisms, the flow of electrons is often shown
using "curved arrows" and in the example shown,
the arrows are designed to show that an unshared
pair of electrons from hydroxide anion moves to
abstract a p...

Paddle Pop Stick 2 Co 3 Flame

Experiments to determine the identity of metals by
examining the colour of flame when samples of that
metal are heated. The aim of this experiment was
to find out whether different metals had different
reactions when subjected to the flame of the
Bunsen burner. This might then allow the
classification and identification of certain
metals if they have their own reactions, which
will be different coloured flames for this
experiment. It was hard for me to predict what
would occur during the experim...

Plant Cells E G

Water has importance inside cells and externally.
This may be because it has interesting chemical
and physical properties; it can be found naturally
in all three of its states. However its molecules
are bonded together by hydrogen bonds, this raises
its melting and boiling points, i. e. its boiling
point would be - 120 C rather than 100 C. Also
because it contains slightly negatively charged
oxygen atoms and slightly positively charged
hydrogen atoms making it polar. Water has been
called a univ...

The Discovery Of The Electron The electron was
discovered in 1895 by J. J. Thomson in the form of
cathode rays, and was the first elementary
particle to be identified. The electron is the
lightest known particle which possesses an
electric charge. Its rest mass is Me equal> 9. 1 x
10 - 28 g, about 1 / 1836 of the mass of the
proton or neutron. The charge of the electron is
-e = - 4. 8 x 10 ^- 10 esu tro static unit). The

The Facts of Life Existence is Truth Everything we
know of is the third dimension, and its
properties. Everything is composed of atoms, and
atoms are composed of smaller particles. All
particles are three dimensional because they have
the dimension of height, the dimension of width,
and the dimension of depth. Air is composed of
particles in a low state of density, water is
composed of particles in a more dense state, and
physical objects are composed of particles in a
high state of density. Thi...

his original field of study. Crick has done some
amazing work in other fields since his famous work
with Watson in the 50 s. Most recently, Crick has

Philosophy, the use of reason and argument in
seeking truth and knowledge of reality. Throughout
history man has searched for the origins of his
existence, both on an outward and inward level,
seeking truth and understanding of his world. The
first culture to actively explore this idea of
philosophy was the Greeks. Because their
civilization placed less emphasis on religion and

Which was came first, the chicken or the egg? One
cant come about without the other. So where did
the first one come from? This is the question
that, people in general as well as scientists,
have been pondering for hundreds of years. There
are several different beliefs, probably more
scientific than Christian, and in this report I
will tell you about four of them. Because there
are so many scientific theories I will be telling
you three of those and one of the Christian. The

Hydrogen Bomb Chain Reaction
409 words
The Hydrogen Bomb The history and workings of this
massive bomb Back in 1905 Albert Einstein
published his special theory of relativity.
According to this theory the relation between mass
and energy is expressed by the equation E = mc
squared, which states that a given mass (m) is
associated with an amount of energy (E) equal to
this mass multiplied by the square of the speed of
light (Encarta). So years later in 1939 two German
chemists took this idea and applied it to a
uranium atom, which wou...

Center Of The Galaxy Super Clusters Small
352 words
The Milky Way is the place we call home, as well
as about 100 billion other stars. It looks very
much like other spiral galaxies when viewed from
above. There are spiral arms and a nucleus. Viewed
from the side, it is about 140, 000 LY in width
and the nucleus (core) is about 20, 000 LY tall.
The entire galaxy travels at around 900, 000 km /
hr . And it takes. 25 x 109 to rotate completly.
The Sun can be found rather far from the center of
the galaxy, halfway to the edge of visible matter

Uv Radiation Ozone Depletion

Our Radiant Planet- Depletion of the Ozone Layer
Ozone is a relatively unstable form of molecular
oxygen containing three oxygen atoms produced when
upper-atmosphere oxygen molecules are split by
ultra violet light. Stratospheric ozone is found
in a broad band, extending generally from 15 to 35
km above the earth. Although the ozone layer is
surprisingly thin, it acts as a protective shield
to the earth, as it filters out most of the
harmful solar ultraviolet radiation (in particular
UV-B) that ...

Neutron Star Black Hole

Black holes by supernova Firstly, a black hole
isnt really a hole at all, but thats the easiest
way to think of its effects on the rest of the
universe. Take a star thats at least thirty times
larger than our sun and make it explode (called a
supernova). Stars do that at the end of their
lifetime, sometimes leaving a remnant of the
violent explosion. The nature of the remnant
depends on its mass. If the remnant is less than
1. 4 solar masses, it will become a white dwarf, a
kind of hot dead star...

Splitting Into Cellular Atoms Splitting Into Cellular People

Spoon River Thomas Rhodes talks about how the
people in Spoon River could have prevented their
hard times. He compared people in Spoon River to
navigators and sailors because they found with all
their boasted wisdom how hard at the last it is to
keep the soul from splitting into cellular atoms.
He also says that seekers of earths treasures are
self-contained and harmonized even to the end. In
this poem you are not told what Thomas does for a
