1) CuCl2 + 2KOH → Cu(OH)2↓ + 2KClCu(OH)2 → CuO + H2OCuO + SO3 → CuSO4CuSO4 + Zn → ZnSO4 + Cu2) 2Ca + O2 → 2CaOCaO + H2O → Ca(OH)2Ca(OH)2 + Zn(NO3)2 → Ca(NO3)2 + Zn(OH)2↓Ca(NO3)2 + ZnSO4 → CaSO4↓ + Zn(NO3)23) S + O2 → SO22SO2 + O2 → 2SO3SO3 + H2O → H2SO43H2SO4 + 2Fe(OH)3 → Fe2(SO4)3 + 6H2O4) 2NH3 → N2 + 3H2N2 + O2 → 2NO2NO + O2 → 2NO24NO2 + 2H2O + O2 → 4HNO3...
