To carry out the above chain of transformations, it is necessary to carry out the following reactions:
The reaction between calcium and oxygen. As a result of the reaction, calcium oxide is formed. The molecular equation of the reaction is as follows:
2 Ca + O2 = 2 CaO
Chemical reaction and equation As a result of the reaction, calcium carbonate is formed. The molecular equation of the reaction is as follows:
CaO + CO2 = CaCO3
Interaction reaction between calcium carbonate and nitric acid. As a result of the reaction, calcium nitrate, water and carbon dioxide are formed. The molecular equation of the reaction is as follows:
CaCO3 + 2 HNO3 = Ca (NO3) 2 + H2O + CO2.
