Remember that when balancing a chemical equation, you can’t add new elements or change the ones already given to you. The only numbers you can change are the coefficients for each chemical, which tell you how many of each substance you need for the reaction to be balanced. In the equation for the formation of water, the coefficients below are 2, 1, and 2.
2 H2 + 1 O2 → 2 H2O
