To calculate the amount of copper sulfide produced, first determine the total mass of the reactants (12.7 g Cu + 3.2 g S = 15.9 g total). According to the law of conservation of mass, the mass of the products will equal the mass of the reactants, so the copper sulfide produced will also weigh 15.9 grams.
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. make it short
