BALANCING CHEMICAL EQUATIONS. Based on the Law of Conservation of Mass, the mass of the reactants must equal the mass of the products. This means that we must have the same number and type of each atom on the reactant side and product side. Example 1: Word Equation: methane + oxygen → carbon dioxide + water. Chemical Equation: CH4 + O2 ...

Balancing chemical equations involves the addition of stoichiometric coefficients to the reactants and products. This is important because a chemical equation must obey the law of conservation of mass and the law of constant proportions, i.e. the same number of atoms of each element must exist on the reactant side and the product side of the equation.
