An investigation into how the amount of oxygen is produced by changing one variable effects the decomposition of Hydrogen Peroxide in the presence of the enzyme. Hydrogen peroxide Water + Oxygen 2 H2O2 2H2O + O2 This shows us that when the H2O2 has reacted with the catalyst this is what it produces. There are many ways in which the amount of oxygen produced could be affected. I believe that, surface area of the chip, temperature of liquid that is reacting, the concentration of the liquid or the amount used are going to be the major...
it was the best we were going to get, I think contamination was minor so that did not cause a problem. One problem with our preliminary experiments was that we had to change the Hydrogen peroxide because we felt that some were to old, and were probably not as concentrated. This could of seriously effected our main experiment with using one chemical but out of several bottles, to eliminate this we must get one bottle big enough for the whole experiment and use that one only; so that there is no change in the quality of the H2O2.

Introduction Osmosis is defined as the diffusion of water molecules, down a water potential gradient, across a partially permeable membrane. If the solutions on each side of the partially permeable membrane are equally concentrated then there will be no net movement of water across the membrane. If the solution...

Prediction I predict that the higher the concentration of salt, the lower the mass the potato cylinder will become. This is because there is a greater concentration of water molecules inside the potato cylinder, so the water will drain from the cylinder by osmosis, to where there was a...

Several methods may be used to prevent aeolian erosion, to increase the height and stability of existing dunes, to repair damaged dunes and to encourage sand accumulation. Where fresh sand deposits around obstructions such as grass clumps show conditions conducive to natural dune formation, plantings of native vegetation or...

Method Ten 50ml beakers were labelled accordingly, e.g. 2 x 0m, 2 x 0.25m, 2 x 0.5, 2 x 0.75 m and 2 x 1m. Distilled water and sugar solution were then measured to vary sugar concentration, into beakers using a pipette. Using a size 4 core borer, sections...
