Question

9.4 g of calcium carbonate on heating gave 4.4 g of carbon dioxide and 5.0 g of calcium oxide. show that these observation are in agreement with law of conservation of mass

Answer 1

Answer:

Yes, these observations are indeed in agreement with the law of conservation of mass.

Explanation:

CaCo3(9.4) -> Co2(4.4) + Cao(5.0)

According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Since RHS = 4.4 + 5 = 9.4 = LHS,  these observations are indeed in agreement with the law of conservation of mass.
