Sodium Chloride Oxygen Beaker Enzyme
DESCRIPTIVE TITLE The Effect of Different Amounts
of Sodium Chloride on the displacement of oxygen.
INTRODUCTION The dependability of the rate of an
enzyme-mediated reaction is based on two factors:
the substrate concentration and the concentration
and action of the enzyme that catalyzes the
reaction (Vander, et. al. , 2001). Enzymes are
catalysts that produce chemical reactions in
cells. Enzymes which are large proteins perform a
reaction which acts upon a substance known as a
substrate. When ...
Neutralizing Acids And Bases
... n juice, and many others. Since I didn't have
a source for hydrochloric acid, I added salt to
vinegar to create HCl. I did the exact same
experiment, using a ten to one acid to base ratio
after testing them with pH paper, carefully wrote
down the results, and then cleaned all of the used
equipment. I repeated this until I could find no
other chemicals to test, and than I made my
charts. Discussion The following documents the
outcome from my experiments. You can find the
rest of the charts e...
Evaluating An Enthalpy Change That Cannot Be Measured Directly
Evaluating An Enthalpy Change That Cannot Be
Measured Directly. Dr. Watson. Introduction. We
were told that sodium hydrogen carbonate
decomposes on heating to give sodium carbonate,
water and carbon dioxide as shown in the equation
below: - 2 NaHCO 3 (s) Na 2 CO 3 (s) + H 2 O (l) +
CO 2 (g) = DeltaH 1 This was given as deltaH 1 and
we had to calculate as part of the experiment.
This however cannot be measured directly, but can
be found using the enthalpy changes from two other
reactions. These ...
Alkali Metals Sodium Compounds Potassium
The six chemical elements that are known as alkali
metals are lithium (Li), sodium (Na), potassium
(K), rubidium (Rb), cesium (Cs), and the extremely
rare radioactive substance called francium (Fr).
Cesium and Francium are the most reactive elements
in this group. The word alkali comes from the
Arabic word al-q ili, meaning plant ashes. Plant
ashes were the first source of alkali metal
compounds. The alkali metals occupy the first
column of the periodic table of the elements.
Since these metals ...
Hardness Ion Water Hard Ions
Solutions & Solubility Pure water, which is an
odour less, colorless, and tasteless substance is
often called the universal solvent. As water moves
through soil, it dissolves very small amounts of
minerals such as calcium and magnesium. The
greater the content of calcium and magnesium, the
more hard the water is. Therefore, hard water is
the result of an excess of two elements, C and Mg.
The hardness of water is measured in grains per
gallon (gig), milligrams per litre (mg / l ) or
parts per mi...
Sodium Bicarbonate Acid Stomach Antacids
Which Antacid Works the Best? Heartburn is a
condition characterized by a burning feeling in
the chest and a sour or bitter taste in the mouth.
Heartburn usually develops when the acidic
contents of the stomach flow back, or regurgitate,
into the esophagus, the muscular tube that carries
food from the throat to the stomach. Approximately
one in ten adults experience heartburn once a
week. Heartburn is more common in pregnant women
because of the pressure the expanding uterus
exerts on the stomac...
Sodium Pure Form
Sodium, a silvery white-metallic element
classified under the alkali metals, has an atomic
number of 11 and a mass of about 23 g. Sodium has
been known since early times and was used by the
people of Mesopotamia and Egypt to make glasses.
Sodium is the sixth most common element found on
the earth, usually not found in nature but more
often in compounds such as salt (Na Cl). It's
regularly found in compounds among dry lake beds,
underground, and as well as in sea water in such
places as: Belarus,...
Minerals Calcium Helps Blood
Minerals Minerals are required to build soft and
hard body tissue. Without then we wouldn't exist.
They also help out with the nervous system the
contraction of mussels and help the blood flow
properly. Minerals are classified into 2 major
groups. The major elements such as calcium,
magnesium, iron, iodine etc. Then the trace
elements such as copper, manganese fluorine and
zinc. Once of the most important is calcium.
Calcium is used to build up your bones. It also
helps to keep your teeth stron...
Fluids And Hydration Sports Drink
How important are fluids? Fluid replacement is
probably the most important nutritional concern
for athletes. Approximately 60% of your body
weight is water. As you exercise, fluid is lost
through your skin as sweat and through your lungs
when you breathe. If this fluid is not replaced at
regular intervals during exercise, you can become
dehydrated. When you are dehydrated, you have a
smaller volume of blood circulating through your
body. Consequently, the amount of blood your heart
pumps with ea...
Sodium Soda Compounds Pure
Life could not exist without compounds of sodium.
These compounds hold water in body tissues, and a
severe deficiency of sodium can cause death. Blood
contains sodium compounds in solution. Sodium
compounds are used in industry in the manufacture
of chemicals and pharmaceuticals, in metallurgy,
in sodium vapor lamps, and in the production of
hundreds of every day products. One of the most
common sodium compounds is table salt, or sodium
chloride. In its pure form sodium is a
silver-white, soft ...
Oxygen Steel Wool
Oxygen content of air Objective: To measure the
percent of oxygen in air and the percent of oxygen
in an exhale of a breath Hypothesis: Air has more
oxygen content in it rather than the exhale of a
human breath. Procedure: Wash hands to remove oils
Obtain 2 samples of steel wool (. 7 g each) Expose
one sample of the wool to 35 mL of vinegar
solution for 1 minute Remove the wool from the
solution and shake it to remove the vinegar Place
the steel wool in a syringe. Put the plunger in

Mixture Of Sodium Or Potassium Soap Water Oil
The Two-Faced Detergent Whether soil particles are
attached to carpet fibers, wood floors or restroom
sinks, they need to be removed. But how is this
done? Most of us wipe or scrub a dirty surface
with soap and water without a second thought about
how they actually work to remove soil. The process
of removing dirt begins at the molecular level. In
order to understand how soap works, we must first
acknowledge what soap actually does. By
definition, soap is a mixture of sodium or
potassium salts a...
Road Salts Sodium Chloride
On Scholar's Day I attended the Environmental
Science presentation entitled "The Environmental
Impacts of Chemical Deicers and Road Salt." I was
required to attend this presentation for my
Environmental Issues class as well. The
presentation was approximately 25 minutes long and
included a powerpoint presentation. In the
presentation itself, it stated the impacts of road
salts and deicers, the state uses on the roadways
during the winter months. The most commonly used
road salt is sodium chlorid...
Action Potential Membrane Nerve Sodium
WHEN the commonplaces of one discipline are
applied to an unrelated field, they can prove
curiously fruitful. In 1952 two British
physiologists, Alan Hodgkin and Andrew Huxley,
managed just such a fruitful crossover, applying
textbook physics to living tissue. They were both
later knighted, and shared a Nobel prize in 1963.
The experimental method they pioneered remains
fundamental to research into the behaviour of
nerve cells. As anyone who has ever had an
electric shock knows, electricity has ...

Sodium Thiosulphate And Hydrochloric Acid
Planning What Am I doing? I am trying to do the
reaction of sodium thiosulphate and hydrochloric
acid, but I am varying the temperature that the
sodium thiosulphate is before I add the
hydrochloric acid. The test is to see the how long
it takes after adding the hydrochloric acid for
you not to see the black cross underneath the
beaker. Method. To dot his reaction first I must
measure out the amounts of sodium thiosulphate and
hydrochloric acid. Then I will heat the sodium
thiosulphate to the re...
The Factor That Affect Rate Of A Reaction
The Factors That Affect the Rate of a Reaction
Planning: There are different factors which can
affect a rate of a reaction such as: o Temperature
o Surface area o Concentration o Catalyst
Concentration - If the concentration of a solution
is increased there are more reactant particles per
unit volume. This increases the probability of
reactant particles colliding with each other
Pressure - If the pressure is increased the
particles in the gas are pushed closer. This
increases the concentration a...

In this article, Richard D. Keynes details the
workings of ion channels in nerve cell membranes.
Nerve impulses (action potentials) are the unit by
which information travels in an organism? s
