Question

can you change this up a bit, The scientist used the law of conservation of mass to predict that the product of the reaction would be 15.9 grams of copper sulfide. According to this law, matter cannot be created or destroyed, so the total mass of the reactants must be equal to the total mass of the products.

Answer 1

The scientist employed the principle of the conservation of mass to anticipate that 15.9 grams of copper sulfide would form as the reaction's end product. As per this principle, the creation or annihilation of matter is impossible, thus necessitating that the combined mass of the reactants matches that of the products.
