In a chemical reaction, the Law of Conservation of Mass states that the total mass of the reactants must equal the total mass of the products.
In this case, the scientist begins with 30 grams of calcium carbonate (CaCO3). During the reaction, it breaks down into carbon dioxide (CO2) and calcium oxide (CaO). Regardless of how the mass is divided among the products, the total mass of the products must equal the mass of the reactants.
Therefore, the total mass of the products will also be 30 grams.
The correct response is:
30 grams
