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)

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

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

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

a: \(Cu+H_2SO_4->CuSO_4+H_2\)

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

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