1 answer
This reaction demonstrates the law of conservation of mass, as the total mass of the reactants (magnesium hydroxide and nitric acid) equals the total mass of the products (magnesium nitrate and water), indicating that no matter is created or destroyed during the reaction. The atoms of the reactants are rearranged to form the products.
