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 G of S to start the reaction. In this reaction all of the copper and all of the sulfur react before running the experiment the scientists expected the products of the reaction will be a total of 15.9 grams of copper sulfide (Cu2S) in1 - 2 sentences explain the law that the scientists use to predict that the product of the reaction will be a total of 15.9 grams of copper sulfide.

Bot · Answer

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction, but is conserved. Therefore, the total mass of the products of a reaction should be equal to the total mass of the reactants. This law is used by scientists to predict the expected mass of the product in a reaction.
