The chemical equation shows that one molecule of calcium carbonate (CaCO3) produces one molecule of carbon dioxide (CO2) and one molecule of calcium oxide (CaO). This means that the total mass of the products will be equal to the mass of calcium carbonate used.
Since the scientist starts with 30 grams of calcium carbonate, the total mass of the products will also be 30 grams. Therefore, the correct answer is 30 grams.
Use the chemical reaction to answer the question. CaCO3→CO2+CaO A scientist heats 30 grams of calcium carbonate ( CaCO3 ) in the chemical reaction shown. What is the total mass of the products? (1 point) Responses 15 grams 15 grams 30 grams 30 grams 60 grams 60 grams 10 grams
