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

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...
Experiment To Investigate The Resistance Of Brine Soaked Paper
This experiment aims to investigate the resistance
of brine soaked paper when an electrical current
is passed through it. Planning: Previous
experiments have taught me that the electrical
resistance will rely on several key variables.
These include the length of paper, its thickness
but most importantly the number of sodium and
chlorine ions carrying the charge. Knowing this, I
have decided to investigate the concentration of
brine in this experiment. To provide an accurate
prediction, I must r...
Investigation Into Osmosis Potato Cylinders
Introduction Knowing that osmosis (a diffusion of
water) will occur across a semi-permeable membrane
whenever there is a difference between the water
concentrations on the two sides of the membrane,
and knowing that when this happens to cells they
will either become turgid if water flows into
them, or plasmolysed if water flows out of them,
and thus change their volume, we want to test the
hypothesis that: If the concentration of a
solution into which a cylinder of potato is placed
is greater th...
Alchemy Middle Ages
Alchemy was alchemy Alchemy Alchemy was a major
part of medieval times. Its practitioners' main
goals were transmutation and transcendence.
Alchemy used the elements of Nature in their
experiments. Only later were our elements of today
adopted. Alchemists also invented many new methods
to use for getting pure forms of the elements.
Alchemy is responsible for many of the techniques
and methods in use today as well as for the many
New Age sciences. Alchemy is one of the more
