       H2         H2SO4        NaOH       HCl            Fe
CuO===>X1=======>X2=====>X3======>X4====>X5

Answer 1

CuO+H2=Cu+H2O

Cu+2H2SO4=CuSO4+SO2+2H2O

CuSO4+2NaOH=Cu(OH)2+Na2SO4

Cu(OH)2+ 2HCl=CuCl2+2H2O

CuCl2 + Fe = FeCl2+Cu

Answer 2

C2H4====>

Answer 3

CuO+H2=Cu+H2O
Cu+H2SO4=CuSO4+SO2+2H2O
CuSO4+2NaOH=Cu(OH)2+Na2SO4
Cu(OH)2+2HCL=CuCL2+2H2O
CuCL2+Fe=Cu+FeCL2
