Answer: C) 2,2
Explanation: In the product H2O2, there are 2 hydrogen atoms and 2 oxygen atoms. H2O has two hydrogen atoms, but not oxygen atoms. So to balance the equation we add the coefficient 2 in front of H2O. Then we also have to add a coefficient 2 in front of H2O2 in order to balance it out.
