B. Because of the conservation of energy

C. Because the volume of reactants must equal the volume of
products

D. Because atoms are not lost or gained in a chemical reaction

These traits describe either a chemical or a nuclear reaction. which statements describe a nuclear reaction? check all that apply. involves the loss, gain, or sharing of electrons may involve a change in total mass involve relatively low energy changes occur outside the nucleus involve very high-energy changes involve changes in nuclides when decay occurs
