Question

Which best represents the reaction of calcium and zinc carbonate (ZnCO3) to form calcium carbonate (CaCO3) and zinc?

Ca → ZnCO3 + CaCO3 → Zn
Ca + ZnCO3 → CaCO3 + Zn
CaCO3 + Zn → Ca + ZnCO3
CaCO3 + Zn + Ca → ZnCO3

Answer 1

The reaction of calcium with zinc carbonate (ZnCO3) to form calcium carbonate (CaCO3) and zinc can be represented by the following balanced equation:

**Ca + ZnCO3 → CaCO3 + Zn**

This equation shows that calcium reacts with zinc carbonate to produce calcium carbonate and zinc, which matches your description of the chemical process. Therefore, the correct representation is:

**Ca + ZnCO3 → CaCO3 + Zn**
