Осуществить химические превращения по следующей цепочке:
CuO → CuSO4 → Cu(OH)2 → CuO → Cu
CuO +H2SO4= CuSO4 +H2O CuSO4 +2NaOH= Cu(OH)2 +Na2SO4
Cu(OH)2 = CuO + H2O
2СuO = 2Cu + O2
CuO+H2SO4=CuSO4+H2O CuSO4+2NaOH=Cu(OH)2+Na2SO4 Cu(OH)2=t=CuO+H2O CuO+H2=Cu+H2O

CuO+H2SO4=CuSO4+H2O
CuSO4+2NaOH=Cu(OH)2+Na2SO4
Cu(OH)2=t=CuO+H2O
CuO+H2=Cu+H2O
