The reaction represented here is a double replacement reaction, also known as a metathesis reaction. In this type of reaction, two compounds exchange ions to form two new compounds.

In this case, calcium carbonate (CaCO3) reacts with sulfuric acid (H2SO4) to form calcium sulfate (CaSO4), water (H2O), and carbon dioxide (CO2). The calcium and sulfate ions from calcium carbonate switch places with the hydrogen and carbonate ions from sulfuric acid to form the new compounds.

The overall reaction can be represented as follows:

```

CaCO3 + H2SO4 → CaSO4 + H2O + CO2

```
