Which of the following is the correct balanced equation for the reaction in which hydrogen peroxide (H2O2) is broken down into hydrogen gas and oxygen gas?
A. H2O2 --> 2H2 + O2
B. 2H2O2 --> 2H2 + O2
C. H2O2 --> H2 + O2
D. H2O2 --> H2 + 2O2
C A has 2H 2O on the left and 4H 2O on the right B has 4H 4O on the left and 4H 2O on the right D has 2H 2O on the left and 2H 4O on the right C has 2H 2O and 2H 2O so is balanced.
