Write the reaction equation: HNO3- Al (NO3) 3- NO2- HNO3- NaNO3

1) 4HNO3 + Al = Al (NO3) 3 + NO + 2H2O (when nitric acid interacts with aluminum, aluminum nitrate, nitrogen oxide (II) and water are formed);

2) 4Al (NO3) 3 = 2Al2O3 + 12NO2 + 3O2 (during the thermal decomposition of aluminum nitrate, aluminum oxide, nitrogen oxide (IV) and oxygen are formed);

3) 2NO2 + H2O = HNO3 + HNO2 (when nitrogen (IV) oxide interacts with water, nitric and nitrous acids are formed);

4) HNO3 + NaOH = NaNO3 + H2O (when nitric acid interacts with sodium hydroxide, sodium nitrate and water are formed).
