1、初三化学方程式下册归纳总结2Mg+O2=2MgO4Al+3O2=2Al2O32Mg+O22MgO4Al+3O22Al2O33Fe+2O2Fe3O42Cu+O22CuOZn+H2SO4=ZnSO4+H2↑Fe+H2SO4=FeSO4+H2↑Mg+H2SO4=MgSO4+H2↑2Al+3H2SO4=Al2(SO4)3+3H2↑Zn+2HCl=ZnCl2+H2↑Fe+2HCl=FeCl2+H2↑Mg+2HCl=MgCl2+H2↑2Al+6HCl=2AlCl3+3H2↑Fe+CuSO4=FeSO4+Cu2Al+3CuS

2、O4=Al2(SO4)3+3CuCu+2AgNO3=Cu(NO3)2+2AgFe2O3+6HCl=2FeCl3+3H2OFe2O3+3H2SO4=Fe2(SO4)3+3H2OCuO+2HCl=CuCl2+H2OCuO+H2SO4=CuSO4+H2OCaO+H2O=Ca(OH)22NaOH+SO2=Na2SO3+H2O2NaOH+CO2=Na2CO3+H2O2NaOH+SO3=Na2SO4+H2OCa(OH)2+CO2=CaCO3↓+H2OCa(OH)2+SO2=CaSO3↓+H2OH2SO4+2NaOH=Na2

3、SO4+2H2OHCl+NaOH=NaCl+H2O2HCl+Ca(OH)2=CaCl2+2H2OH2SO4+Ca(OH)2=CaSO4+2H2O3HCl+Al(OH)3=AlCl3+3H2OCaCO3+2HCl=CaCl2+H2O+CO2↑Na2CO3+2HCl=2NaCl+H2O+CO2↑NaHCO3+HCl=NaCl+H2O+CO2↑Ca(OH)2+Na2CO3=CaCO3↓+2NaOH
