According to the law of conservation of mass, the total mass of the products of a chemical reaction should equal the total mass of the reactants. In our reaction on a balance, however, the mass went down, from 253.0 g to 250.2 grams. Using the given chemical equation, explain what caused the apparent loss of mass.
