displacement has two compounds as reactants and the elments in each compound exchange places. The way to test the presence of oxygen gas is by putting a glowing splint of a match in a substance that may contain oxygen. The evidence resercher look for oxygen gas is if the splint lights up. The way to test the presence of hydrogen gas is by using a burning splint. The evidence resercher look for hydrogen gas if the gas makes a “popping” sound. The way to test the presence of carbon dioxide gas is its reaction

441 Enzyme Lab 10.12.2012 Period 3-4 Purpose/Objective: The purpose/objective of this lab was to see if environmental conditions changed the speed of the reaction. The catalyst being used was the spark (the match). The Chemical reaction being tested was how fast the hydrogen peroxide could turn into water and oxygen. The theory that was being tested was; Enzymes speed up reactions. The facts that I wanted to determine were matches making the chemical reaction happen quicker or not
