Write the reaction equations: N2 → NH3 → NO → NO2 → HNO3 → Ba (NO3) 2

A chain of transformations is a sequential implementation of reactions.
The number of arrows in it corresponds to the number of reactions.
1.N2 + 3H2 = 2NH3 (compound)
2.4NH3 + 5O2 = 4NO + 6H2O (substitution)
3.2NO + O2 = 2NO2 (compound)
4.4NO2 + 2H2O + O2 = 4HNO3 (compound)
5. BaO + 2HNO3 = Ba (NO3) 2 + H2O (exchange)
