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 60 grams 60 grams 30 grams 30 grams 10 grams 10 grams 15 grams
The total mass of the products is 30 grams.
This is because according to the balanced chemical equation, 1 mole of calcium carbonate (CaCO3) produces 1 mole of carbon dioxide (CO2) and 1 mole of calcium oxide (CaO). Since the molar mass of CaCO3 is 100 g/mol, when 30 grams of CaCO3 is reacted, it will produce 30 grams of CO2 and 30 grams of CaO.
So, the total mass of the products is 30 grams.
