copper reacts with sulfur to form copper sulfide as shown in the equation a scientist adds 12.7 g of CU 23.2 g of S to start reaction in this reaction. All of the copper and all this sulfur react before running the experiment the scientist expected the products of the reaction will be a total of 15.9 g of copper sulfide in 1-2 sentences explain the law that the scientist used to predict that the product of reaction will be 15.9 g of copper sulfide

The scientist used the Law of Conservation of Mass to predict that the total mass of the reactants would be equal to the total mass of the products in the chemical reaction. This law states that matter cannot be created or destroyed in a chemical reaction, only transformed from one form to another.
