The equation below represents the chemical reaction between the elements hydrogen and oxygen when the compound water is formed. (AKS 4c, DOK 1) image This equation supports the law of conservation of mass because A. the total number of hydrogen and oxygen atoms in the reactants and products is twelve. B. atoms of the elements hydrogen and oxygen are in the reactants and also in the products. C. the mass of hydrogen and oxygen in the reactants is equal to the mass of the water in the product. D. atoms of the elements hydrogen and oxygen react to form molecules of the compound water.
