Consider the unbalanced chemical equation. H2O(l)−→−−−−−−−−electrical currentH2(g)+O2(g)H2O(l)→electrical currentH2(g)+O2(g) A chemistry student tries to balance the equation by placing the subscript 2 after the oxygen atom in H2OH2O.   Placing the subscript 2 after H2OH2O would change the _______of molecules, not the ______ of molecules. It results in H2O2, which is ______. To balance chemical reactions, one must add ______, not subscripts.
