1. When sodium chloride is heated, free chlorine is released:
2NaCl = Cl2 + 2Na.
2. Combustion of hydrogen in chlorine vapor:
Cl2 + H2 = 2HCl.
3. Interaction of copper oxide with hydrochloric acid:
2HCl + CuO = CuCl2 + H2O.
4. Precipitation of a white precipitate of silver chloride:
CuCl2 + AgNO3 = 2AgCl + Cu (NO3) 2.
