B. Mass was lost in this chemical reaction because the atoms in the reactants are smaller than the atoms in the products.

C. Mass was conserved in this chemical reaction because the same atoms are present in both the products and the reactants.

D. Mass was gained in this chemical reaction because there are more atoms in the products than there were in the reactants.
