\(\text{CuO+2HCl(dung dịch pha loãng)=CuCl2+H2O}\)
\(\text{Ca(OH)2+CuCl2→Cu(OH)2↓+CaCl2}\)
\(\text{Cu(OH)2 → CuO + H2O}\)
\(\text{CuO + H2SO4 → H2O + CuSO4}\)
\(\text{CuSO4(dung dịch pha loãng)+H2=Cu↓+H2SO4}\)
PT cuối sai
\(CuO+2HCl->CuCl_2+H_2O\)
\(CuCl_2+2NaOH->Cu\left(OH\right)_2+2NaCl\)
\(Cu\left(OH\right)_2->CuO+H_2O\) (Nhiệt độ nữa nha bạn)
\(CuO+H_2SO_4->CuSO_4+H_2O\)
\(CuSO_4\:+Fe->FeSO_4+Cu\)
\(Cu+2AgNO_3->Cu\left(NO_3\right)_2+2Ag\)

CuO+2HCl--->CuCl2+H2O
CuCl2+2NaOH--->Cu(OH)2+2NaCl
Cu(OH)2--->CuO+H2O
CuO+H2SO4--->CuSO4+H2O
CuSO4+Fe-->FeSO4+Cu
Cu+2AgNO3--->Cu(NO3)2+2Ag
CuO
CuCl2
Cu(OH)2
CuO
CuSO4
