Write down the reaction equations: HCL-CL2-CuCL2-Cu (OH) 2-CuO-Cu

2HCl + O2 = 2H2O + Cl2 is an exchange reaction resulting in the formation of water and chlorine gas.
Cu + Cl2 (t) = CuCl2 – when heated, copper reacts with chlorine, a combination reaction, as a result of which copper chloride is formed.
CuCl2 + 2NaOH = Cu (OH2) + 2NaCl is an exchange reaction, as a result of which sodium salt and copper hydroxide are formed from copper salt and sodium hydroxide.
Cu (OH2) = CuO + H2O – decomposition reaction, copper oxide and water are formed from copper hydroxide.
СuO + Н2 = Cu + Н2O – by reduction of copper with hydrogen, you can get metallic copper and water.
