Write the reaction equation: N2- NO- N2O5- HNO3

Let us write down the reaction equations for inorganic substances:
1. N2 + O2 = 2NO – the reaction of the compound, nitric oxide was obtained (2);
2. 2NO + O2 = 2NO2 – redox (ORR), nitrogen oxide is released (4);
3. NO2 + NO + O2 = N2O5 – ОВР, nitrogen oxide was formed (5);
4. N2O5 + H2O = 2HNO3 – acid oxide reacts with water, nitric acid is obtained, the reaction is reversible.
The above reactions show the connection of a simple nitrogen substance with acid oxides, acid. The reaction products find practical applications, for example, nitric acid, is used to obtain nitrates, and is also a strong oxidizing agent.
