Introduction The objective of this lab was to show how stoichiometry is applied to a specific chemical reaction. Stoichiometry is pretty much the math behind chemistry. Doing stoichiometry can calculate masses‚ moles‚ and percents with a chemical equation. The use of stoichiometry is how we were able to find the limiting reagent in this lab. A limiting reagent is the chemical that will be used up first. Many calculations had to be made throughout this lab. Some of the calculations we made were

to break it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables such a pH and temperature we are able to how the rate of reaction is altered or improved. If it has improved
