Decomposition of Hydrogen Peroxide

Abstract: This lab was designed to observe the decomposition of hydrogen peroxide into it oxygen and water. The equation for this reaction is H202 H2O + +1/2O2 thus by measuring volume and pressure of O2 generated the amount of O2 generated can be calculated which in turn can be utilized to determine the concentration of… View Article

Kinetics of H2O2 Decomposition

Introduction When measuring the rate of a reaction one can measure the rate at which one of the product appears or the rate at which the reactants disappear. The actual rate of a chemical reaction however is dependent on two things; the temperature the actual experiment is performed at, and the concentration pertaining to the… View Article

Anatomy: Respiratory System

Introduction The primary function of the respiratory system is to supply the blood with oxygen. The respiratory system does this through breathing. Breathing is a natural process that we use to obtain oxygen, unlike eating or drinking to get energy. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is… View Article

The Catalase Lab

Conclusion- The Researcher’s hypothesis, “If more catalase is added then more oxygen (kPa) will be produced in a faster rate because there is more catalase to react upon” and “if less catalase is added then less oxygen (kPa) will be produced in a slower rate because there is less catalase to react upon.” It was… View Article
