1) 4Al + 3O2 = 2Al2O3 (when aluminum interacts with oxygen, aluminum oxide is formed);
2) Al2O3 + 6HCl = 2AlCl3 + 3H2O (when aluminum oxide interacts with hydrochloric acid, aluminum chloride and water are formed);
3) AlCl3 + 3H2O = Al (OH) 3 + 3HCl (when aluminum chloride interacts with water, aluminum hydroxide and hydrochloric acid are formed);
4) 2Al (OH) 3 = Al2O3 + 3H2O (when aluminum hydroxide decomposes, aluminum oxide and water are formed);
5) Al2O3 + 3N2O5 = 2Al (NO3) 3 (when aluminum oxide interacts with nitrogen oxide (V), aluminum nitrate is formed).
