2Cu+O2=2CuO
CuO+2HCl=СuCl2+H2O
CuCl2+2NaOH=2NaCl+Cu(OH)2- осадок
Cu(OH)2=CuO+H2O
CuO+H2SO4=CuSO4+H2O
2Cu+O2=2CuO
CuO+2HCl=СuCl2+H2O
CuCl2+2NaOH=2NaCl+Cu(OH)2- осадок
Cu(OH)2=CuO+H2O
CuO+H2SO4=CuSO4+H2O
CuO + 2HC1(разб.) = CuCl2 + H2O
CuCl2 + 2NaOH(разб.) = Cu(OH)2↓ + 2NaCl
Cu(OH)2 = CuO + H2O
CuO + H2SO4 = CuSO4 + H2O
