The scientist used the Law of Conservation of Mass to guess that the reaction would produce 15.9 grams of copper sulfide. This law says that matter can't be created or destroyed in a chemical reaction. That means the total weight of the things you start with (the reactants) has to be the same as the total weight of what you end up with (the products).
rewrite as a 7th grader The scientist utilized the Law of Conservation of Mass to predict that the reaction would yield 15.9 grams of copper sulfide. This principle indicates that matter cannot be created or annihilated in a chemical reaction. As a result, the combined mass of the reactants must be equal to the combined mass of the resulting products.
