1) CuO + CO → Cu + CO2 (copper, carbon dioxide (carbon monoxide (IV); substitution reaction).
2) Сu + 4HNO3 (conc.) → Cu (NO3) 2 + 2NO2 + 2H2O (copper nitrate, nitrogen oxide (IV); redox reaction).
3) Cu (NO3) 2 + 2KOH → 2KNO3 + Cu (OH) 2 (potassium nitrate, copper (II) hydroxide; exchange reaction, the reaction proceeds, since a precipitate is formed in the form of copper (II) hydroxide).
4) Cu (OH) 2 → CuO + H2O (conditions: temperature; copper (II) oxide; decomposition reaction).
