\(CuSO_4+BaCl_2->CuCl_2+BaSO_4\)

\(2CuCl_2+O_2->2CuO+2Cl_2\)

2Cu + O₂ ---> 2CuO

CuO + HCl ---> CuCl₂ + H₂O

CuCl₂ + Ba(OH)₂ ---> Cu(OH)₂ + BaCl₂

Cu(OH)₂ ---t^o--> CuO + H₂O

CuO + SO₃ ---> CuSO₄

CuSO₄ + Pb(NO₃)₂ --->Cu(NO₃)₂ + PbSO₄

\(\text{CuO+2HCl(dung dịch pha loãng)=CuCl2+H2O}\)

\(\text{Ca(OH)2+CuCl2→Cu(OH)2↓+CaCl2}\)

\(\text{Cu(OH)2 → CuO + H2O}\)

\(\text{CuO + H2SO4 → H2O + CuSO4}\)

\(\text{CuSO4(dung dịch pha loãng)+H2=Cu↓+H2SO4}\)

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)

\(CuO+H_2SO_4->CuSO_4+H_2O\)

\(CuSO_4\:+Fe->FeSO_4+Cu\)

\(Cu+2AgNO_3->Cu\left(NO_3\right)_2+2Ag\)

Cu + Cl₂→ CuCl₂

CuCl₂ + 2NaOH → Cu(OH)₂ +2 NaCl

Cu(OH)₂ \(\underrightarrow{t^°}\) CuO + H₂O 

CuO +H₂SO₄ →CuSO₄ +H₂O

CuSO₄ +BaCl₂ → BaSO₄ + CuCl₂

$Cu(OH)_2 \xrightarrow{t^o} CuO + H_2O$
$CuO + H_2SO_4 \to CuSO_4 + H_2O$
$CuSO_4 + BaCl_2 \to BaSO_4 + CuCl_2$
$CuCl_2 + 2AgNO_3 \to 2AgCl + Cu(NO_3)_2$
$Cu(NO_3)_2 + Fe \to Cu + Fe(NO_3)_2$
$2Cu + O_2 \xrightarrow{t^o} 2CuO$
