Answer:

C

Explanation:

All equations must be balanced, therefore there cannot be a smaller or larger mass on one side.

A decomposition reaction of calcium carbonate results in calcium oxide and carbon dioxide. The mass of CaCO₃ is equal to the sum of the mass of the product. Thus, option C is correct.

What is conservation of mass?

Conservation of mass is the law that gives the relation between the mass of the reactant and of the product formed after it underwent a reaction.

The decomposition reaction of calcium carbonate is:

CaCO₃ → CaO + CO₂

This concludes that a balanced reaction has the same mass on the reactant and the product.

Therefore, option C. mass of calcium carbonate is equal to the mass of CaO and CO₂.
