Write the reaction equations: Ca – CaO – Ca (OH) 2 – CaCl2 Cu – CuO – CuCl2 – Cu – CuCuSO4

1.Ca -> CaO -> Ca (OH) 2 -> CaCl2
2Ca + O2 = 2CaO;
CaO + H2O = Ca (OH) 2;
Ca (OH) 2 + 2KCl = CaCl2 + 2KOH.
2.Cu -> CuO -> CuCl2 – Cu
2Cu + O2 = 2CuO;
CuO + 2HCl = CuCl2 + H2O;
CuCl2 + Mg = MgCl2 + Cu
3. Cu <–CuO–> CuSO4
2CuO = 2Cu + O2;
CuO + ZnSO4 = CuSO4 + ZnO.
