How does a chemical equation with coefficients relate to the law of conservation of mass? A. The total mass must remain constant in a chemical reaction with coefficients in order for a physical change to occur
B. The number of atoms of each element must remain the same before and after a reaction in order for mass of the products to be the same as the mass of the reactants
C. The total mass of the reactants cannot equal the total mass of the products
D. The number of atoms in each element must change after the reaction in order for the mass to remain constant
