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. The scientist needs to determine how many grams of copper sulfide the reaction will produce. In 1–2 sentences, explain how to calculate the amount of copper sulfate this reaction will produce. Use the law of conservation of mass in the explanation.

To calculate the amount of copper sulfide produced in this reaction, you can use the law of conservation of mass, which states that the total mass of the reactants must equal the total mass of the products. First, calculate the molar mass of Cu and S, then determine the limiting reactant. Use the stoichiometry of the balanced chemical equation to find the moles of copper sulfide produced, and finally, convert moles to grams to determine the amount of copper sulfide produced.
