Based on the Law of Conservation of Mass, the total mass of the reactants before a chemical reaction will be equal to the total mass of the products after the chemical reaction, assuming the reaction takes place in a closed system where no mass is lost to the surroundings.
The given chemical reaction is:
CaCO3 → CO2 + CaO
If the scientist heats 30 grams of calcium carbonate (CaCO3), then the total mass of carbon dioxide (CO2) and calcium oxide (CaO) produced will also be 30 grams, because the mass is conserved during the chemical reaction.
Therefore, the correct response is:
30 grams
