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
em tham khảo nha

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
\(Cu+Cl_2\xrightarrow[]{t^0}CuCl_2\\ CuCl_2+2AgNO_3\rightarrow Cu\left(NO_3\right)_2+2AgCl\\ Cu\left(NO_3\right)_2+2KOH\rightarrow Cu\left(OH\right)_2+2KNO_3\\ Cu\left(OH\right)_2\xrightarrow[]{t^0}CuO+H_2O\\ CuO+H_2SO_4\rightarrow CuSO_4+H_2O\\ CuSO_4+Mg\rightarrow MgSO_4+Cu\)
Cu+Cl2➝CuCl2
CuCl2+2AgNO3➝Cu(NO3)2+2AgCl↓
Cu(NO3)2+2NaOH➝ Cu(OH)2↓+2NaNO3
Cu(OH)2➝CuO+H2O
CuO+H2SO4➝CuSO4+H2O
CuSO4+Mg(OH)2➝Cu(OH)2↓+MgSO4
\(\text{CuO+2HCl(dung dịch pha loãng)=CuCl2+H2O}\)
\(\text{Ca(OH)2+CuCl2→Cu(OH)2↓+CaCl2}\)
\(\text{Cu(OH)2 → CuO + H2O}\)
\(\text{CuO + H2SO4 → H2O + CuSO4}\)
\(\text{CuSO4(dung dịch pha loãng)+H2=Cu↓+H2SO4}\)
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)
\(CuO+H_2SO_4->CuSO_4+H_2O\)
\(CuSO_4\:+Fe->FeSO_4+Cu\)
\(Cu+2AgNO_3->Cu\left(NO_3\right)_2+2Ag\)
\(\left(4\right)CuO+H_2SO_4\rightarrow CuSO_4+H_2O\)
\(K_2O,BaO,Na_2O,CaO,Li_2O\) mới td đc với oxit axit chứ a
\(\left(1\right)CuO+2HCl\rightarrow CuCl_2+H_2O\\ \left(2\right)CuCl_2+2KOH\rightarrow Cu\left(OH\right)_2\downarrow+2KCl\\ \left(3\right)Cu\left(OH\right)_2\rightarrow\left(t^o\right)CuO+H_2O\\ \left(4\right)CuO+H_2SO_4\rightarrow CuSO_4+H_2O\)
\(2Cu+O_2\underrightarrow{t^o}2CuO\)
\(CuO+2HCl\rightarrow CuCl_2+H_2O\)
\(CuCl_2+2NaOH\rightarrow2NaCl+Cu\left(OH\right)_2\)
\(Cu\left(OH\right)_2+H_2SO_4\rightarrow CuSO_4+2H_2O\)
