1) 2Сu + O2 → 2CuO (copper (II) oxide, compound reaction).
2) CuO + 2HCl → CuCl2 + H2O (copper (II) chloride, exchange reaction, the reaction proceeds, since a weak electrolyte is formed in the form of water).
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) Cu (OH) 2 + 2HNO3 → Cu (NO3) 2 + 2H2O (copper (II) nitrate; exchange reaction, the reaction proceeds, since a weak electrolyte is formed in the form of water).
5) Cu (NO3) 2 + K2S → CuS + 2KNO3 (copper (II) sulfide, potassium nitrate; exchange reaction, the reaction proceeds, since a precipitate is formed in the form of copper (II) sulfide).
