Calcium carbonate (CaCO3) is a white solid with no odor. When CaCO3 is heated, the resulting substances are calcium oxide (CaO) and carbon dioxide (CO2). CaO is a white to gray solid with no odor, and CO2 is a gas with no odor and color.
Which statement describes CaCO3?
A) It is a diatomic molecule that can’t be broken down by physical means.
B) It is a diatomic molecule that can’t be broken down by chemical means.
C) It is a compound that can be broken down by physical means.
D) It is a compound that can be broken down by chemical means.
