Объяснение:
Cu+2H2SO4=CuSO4+SO2+2H2O
CuSO4+2NaOH=Cu(OH)2+Na2SO4
Cu(OH)2-> CuO+H2O
CuO+2HCl=CuCl2+H2O
Cu(OH)2+2HCl=CuCl2+2H2O
Cu-CuO-CuSO4-Cu(OH)2-CuCl2-CuO=Cu
2Cu + O2 = 2CuO
CuO + H2SO4 = CuSO4 + H2O
CuSO4 + 2NaOH = Na2SO4 + Cu(OH)2
Cu(OH)2 + 2HCl = CuCl2 + 2H2O
CuCl2 + 2NaOH=CuO+ H2O + 2NaCl
CuO+H2=Cu+H2O
