8.5 Degrees

The Law of Conservation of Mass states that -

• the number and type of atoms on both sides of a chemical reaction are equal

• there are more atoms on the reactant side than the product side

• there are more atoms on the product side than the reactant side

• the mass of the product will not equal the reactants
