SCH4U7-02 Monday‚ October 21‚ 2013 Designing an Experiment to Investigate Factors Affecting Rate of Reaction Introduction Hydrogen Peroxide (H2O2)‚ is the most simple peroxide and commonly used in several household items such as toothpaste or as an alternative to bleach. However hydrogen peroxide it is a very dangerous substance when accumulated in large amounts. If that situation occurs this substance must be decomposed. But how can we decompose this reaction? Well it decomposes by itself

Background: As members of the class Amphibia‚ frogs may live some of their adult lives on land‚ but they must return to water to reproduce. Eggs are laid and fertilized in water. On the outside of the frog’s head are two external nares‚ or nostrils; two tympani‚ or eardrums; and two eyes‚ each of which has three lids. The third lid‚ called the nictitating membrane‚ is transparent. Inside the mouth are two internal nares‚ or openings into the nostrils; two vomerine teeth in the middle of the roof
