Balanced chemical equations, which represent reactions, include coefficients that describe the ratio between the reactants and products. A balanced chemical equation not only describes how many molecules or moles react with each other, but it also embodies the fact that matter and mass are conserved in a reaction. This means that all of the atoms present among the reactants will be present in the same amount among the products. For example, the combustion reaction between methane and oxygen can be...
