Use the chemical equation to complete the activity.
2Cu+S→Cu2S
Copper (Cu) reacts with sulfur (S) to form copper sulfide as shown in the equation. A scientist adds 12.7 grams of Cu to 3.2 grams of S to start the reaction. In this reaction, all of the copper and all of the sulfur react. Before running the experiment, the scientist expected the products of the reaction will be a total of 15.9 grams of copper sulfide (Cu2S). In 1–2 sentences, explain the law that the scientist used to predict that the product of the reaction would be 15.9 grams of copper sulfide.

The scientist used the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. This means that the total mass of the reactants (copper and sulfur) must equal the total mass of the products (copper sulfide), so the scientist added the mass of copper and sulfur together to predict the total mass of the product.
