Making models of substances like sulfuric acid (H2SO4) helps us see how the atoms are arranged and connected. This is important because it makes it easier to understand how these chemicals behave and interact with each other!
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 to predict that the total mass of the products would equal the total mass of the reactants. Since 12.7 grams of copper and 3.2 grams of sulfur were used in the reaction, adding these together gives a total of 15.9 grams of copper sulfide (Cu2S) produced.
