Which of the following is NOT a useful tip in balancing chemical equations? Change the formula of the compounds so that the atoms balance on the reactants and products side of the equation. Balance polyatomic ions as single entities if they appear on both sides of the equation. Start with all other elements other than hydrogen and oxygen. If there are an even number of atoms on one side and an odd number of atoms on the other side begin by multiplying the odds by 2.
