In the chain of transformations, it is necessary to number the arrows. The number of reaction equations must be equal to the number of arrows.

1. CaCO3 = CaO + CO2 (when heated);

2. CO2 + Ca (OH) 2 = CaCO3 + H2O;

3. CaCO3 + H2O + CO2 = Ca (HCO3) 2;

4. Ca (HCO3) 2 = CaCO3 + H2O + CO2 (when heated).
