When heated, calcium carbonate goes through a chemical reaction, and produces calcium oxide (quick lime) powder and carbon

dioxide gas. A chemist performed this reaction in a lab and found that the mass of the calcium oxide (quick lime) was less than the

mass of the calcium carbonate. What is the reason behind this decrease in mass?

A. The carbon dioxide molecules produced were unstable and lighter in mass.

B. Calcium oxide crystals produced break up at room temperature, leading to the difference in

C. Carbon dioxide is produced, and as a gas, it was not captured to measure its mass.

D.

The calcium oxide crystals produced were unstable and lighter in mass.
