1)2Zn+O2=2ZnO
2Al+3Cl2=2AlCl3
H2O+SO3=H2SO4
Fe+Cl2=FeCl2
2)Fe+H2SO4=FeSO4+H2
H2+CuO=Cu+H2O
Mg+2HCl=MgCl2+H2
3)CaCO3=CaO+CO2
2Ag2O=4Ag+O2
2NH3=N2+3H2
Cu(OH)2=CuO+H2O
4)3NaOH+H3PO4=Na3PO4+3H2O
2AgNo3+MgCl2=Mg(NO3)2+2AgCl
2KOH+H2SO4=K2SO4+2H2O

C2H6 + Cl2 = C2H5Cl + HCl
C2H5Cl + [Ag(NH3)2]OH = C2H5OH + AgCl + 2NH3
C2H5OH + CuO = CH3COH + Cu + H2O
2CH3COH + O2 = 2CH3COOH
M(Mn(OH)2)=55+(16+1)*2=89
