Answer

Explanation:

Step1: Write the reactants

The reactants are (CaO) (calcium oxide) and (CO_{2}) (carbon - dioxide).

Step2: Combine elements based on conservation of mass

When (CaO) and (CO_{2}) react, the calcium ((Ca)), carbon ((C)), and oxygen ((O)) atoms combine. Calcium has a + 2 charge, carbonate ((CO_{3}^{2 -})) has a - 2 charge. The chemical reaction is (CaO+CO_{2}\rightarrow CaCO_{3}).

Answer:

A. (CaCO_{3})
