Chúc bạn học tốt
PTHH:
Cu + H2SO4 → H2 + CuSO4
CuSO4 + BaCl2 → BaSO4 + CuCl2
CuCl2 + Ba(OH)2 → BaCl2 + Cu(OH)2
Cu(OH)2 \(\underrightarrow{t^0}\) H2O + CuO
2CuO \(\underrightarrow{t^0}\) 2Cu + O2
Cu + H2SO4(ĐẶC NÓNG) -\(t^O\)> CuSO4 + 2H2O + SO2
CuSO4 + BACL2 -> CuCL2 + BASO4
CuCL2 + Pb(OH)2 -> Cu(OH)2 + PbCL2
Cu(OH)2 -\(t^O\)> CuO + H2O
CuO + H2 -\(t^O\)> Cu + H2O
CuCl2 + Ba(OH)2 \(\rightarrow\) Cu(OH)2 + BaCl2
Cu(OH)2 \(\underrightarrow{t^0}\) CuO + H2O
CuO + H2SO4 \(\rightarrow\) CuSO4 + H2O
CuSO4 + Ba(NO3)2 \(\rightarrow\) Cu(NO3)2 + BaSO4
2Cu + O2 ---> 2CuO
CuO + HCl ---> CuCl2 + H2O
CuCl2 + Ba(OH)2 ---> Cu(OH)2 + BaCl2
Cu(OH)2 ---to--> CuO + H2O
CuO + SO3 ---> CuSO4
CuSO4 + Pb(NO3)2 --->Cu(NO3)2 + PbSO4

\(2Cu+O_2\underrightarrow{t^o}2CuO\)
\(CuO+2HCl\rightarrow CuCl_2+H_2O\)
\(CuCl_2+2NaOH\rightarrow2NaCl+Cu\left(OH\right)_2\)
\(Cu\left(OH\right)_2+H_2SO_4\rightarrow CuSO_4+2H_2O\)
\(\text{CuO+2HCl(dung dịch pha loãng)=CuCl2+H2O}\)
\(\text{Ca(OH)2+CuCl2→Cu(OH)2↓+CaCl2}\)
\(\text{Cu(OH)2 → CuO + H2O}\)
\(\text{CuO + H2SO4 → H2O + CuSO4}\)
\(\text{CuSO4(dung dịch pha loãng)+H2=Cu↓+H2SO4}\)
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)
\(CuO+H_2SO_4->CuSO_4+H_2O\)
\(CuSO_4\:+Fe->FeSO_4+Cu\)
\(Cu+2AgNO_3->Cu\left(NO_3\right)_2+2Ag\)
\(\left(1\right)CuCl_2+2NaOH\rightarrow Cu\left(OH\right)_2+NaCl\)
\(\left(2\right)Cu\left(OH\right)_2+H_2SO_4\rightarrow CuSO_4+2H_2O\)
\(\left(3\right)CuSO_4+2NaCl\rightarrow Na_2SO_4+CuCl_2\)
\(CuCl_2+2NaOH\rightarrow Cu\left(OH\right)_2+2NaCl\\ Cu\left(OH\right)_2+H_2SO_4\rightarrow CuSO_4+2H_2O\\ CuSO_4+BaCl_2\rightarrow CuCl_2+BaSO_4\)
