Write the reaction equations: Ca- CaO- Ca (NO3) 2- CaCO3

In this task you need to compose chemical reactions for the following chains of compounds.

Ca -> CaO -> Ca (NO3) 2 -> CaCO3.

Addition reaction.

2Ca + O2 = 2CaO.

When calcium interacts with oxygen, calcium oxide is formed as a result.

Compound reaction.

CaO + CO2 = CaCO3.

When calcium oxide interacts with carbon monoxide, calcium carbonate is formed as a result.

Exchange reaction.

CaCO3 + 2HNO3 = Ca (NO3) 2 + H2O + CO2.

when calcium carbonate interacts with nitric acid, calcium nitrate, water and carbon dioxide are formed as a result.
