... In this example we started with 2 atoms of hydrogen and we ended with 2 atoms of hydrogen. But we started with only one atom of oxygen and ended with 2 atoms of oxygen. We cannot change the numbers at the bottom of the symbols because that is how the formulas must be written. To balance the equation ...
