Answer:
Law of conservation of mass can be used to solve this answer.
Explanation:
Law of conservation of mass states that mass neither be created nor destroyed in a chemical reaction.
So,
Mass of reactants = Mass of product
Mass of calcium oxide + Mass of carbon dioxide = Mass of calcium carbonate
5.6g + Mass of carbon dioxide = 10g
Mass of carbon dioxide = 10g - 5.6g
Therefore, mass of carbon dioxide = 4.4g
