The masses of reactants and products are equal.
... In many other chemical reactions, mass also appears to decrease. That is, the mass of the products appears to be less than the mass of the reactants. In other reactions, the products appear to gain mass. For example, plants grow through a complex series of reactions, but where does their extra mass ...
