When we put the yeast in the hydrogen peroxide the temperature started to rise. This is an example of an exothermic reaction. Our lowest temperature was 17 degrees Celsius and our highest temperature was 39 degrees Celsius.  

Breakdown of the Reaction

Unbalanced: H2O2 --> H2O + O2

In this reaction yeast was mixed with hydrogen peroxide. The yeast would act as the catalyst. The hydrogen peroxide broke down to give us a water molecule and an oxygen molecule. This is a decomposition reaction. The reactant is hydrogen peroxide and the products were water and oxygen. This reaction does obey the law of conversation

reactants:                                                                                    products:

4 hydrogen                                                                                4 hydrogen

4 oxygen                                                                                     4 oxygen

Balanced: 2H2O2 --> 2H2O + O2
