1) 4HCl + MnO2 → MnCl2 + Cl2 + 2H2O (manganese (II) chloride, chlorine; redox reaction).
2) Cl2 + Cu → CuCl2 (copper (II) chloride; compound reaction).
3) CuCl2 + 2NaOH → Cu (OH) 2 + 2NaCl (copper (II) hydroxide, sodium chloride; exchange reaction, the reaction proceeds, since a precipitate is formed in the form of copper (II) hydroxide).
4) Сu (OH) 2 → СuO + H2O (conditions: temperature; copper (II) oxide; decomposition reaction of insoluble bases).
5) СuO + H2 → Cu + H2O (copper; substitution reaction).
