O Yes because the law of conservation of energy is followed. There are equal
amounts of energy in the reactants and products,
O No because the law of conservation of mass is not being followed. The
hydrogen and chlorine atoms have different numbers of atoms in the
reactants and products.
Yes because the law of conservation of matter is being followed. The mass of
the reactants is equal to the mass of the products.
No because the law of conservation of energy is not followed. There are
different amounts of energy in the reactants and products.
