Answer:
Step-by-step explanation:
Hello there!
In this case, since we are talking about a decomposition reaction whereby calcium carbonate is decomposed to calcium oxide and carbon dioxide according to the following chemical equation:
Next, we must recall the law of conservation of mass which states that matter cannot be neither created nor destroyed so the mass of calcium carbonate equal the addition of the mass of both calcium oxide and carbon dioxide:
Which must be solved for the mass of carbon dioxide as we are given those of calcium carbonate and calcium oxide:
Best regards!
