写出实现下列转化的化学方程式,如果是在水溶液中进行的反应,请写出离子方程式

CH2=CH2+H2O→CH3CH2OH2CH3CH2OH+O2→2CH3CHO+2H2O2CH3CHO+O2→2CH3COOHCH3COOH+CH3CH2OH→CH3COOCH2CH3+H2O

mg+2hcl=mgcl2+h2mgcl2+2naoh=mg(oh)2+2naclmg(oh)2+h2so4=mgso4+2h2ocuo+h2so4=cuso4+h2ocuso4+2naoh=cu(o

(1)FeS+H2===(加热)Fe+H2S(2)H2S+HgCl2===2HCl+HgS(沉淀)（3）H2S+NaClO===S+NaCl+H2O（4）S+Hg===HgS(5)S+O2===(点燃

   第十二个不行吧,从本质上讲不会反应!

Na2CO3+Hcl=H2O+Nacl+CO2Na2CO3+H2SO4=Na2SO4+H2O+CO2NaOH+HCl=Nacl+H2OCUSO4+Fe=FeSO4+Cu

CuO+H2SO4=CuSO4+H2O第二个是不是Zn→H2?Zn+H2SO4=ZnSO4+H2↑

我知道!百分百正确!①C+O2=点燃=CO2②CaCO3+2HCl=CaCl2+H2O+CO2↑③H2CO3=△=CO2↑+H2O④C+CO2=高温=2CO

Na(OH)+HCl=NaCl+H2O

3Fe+2O2=Fe3O4Fe+CuSO4=FeSO4+Cu2Cu+O2=2CuOFe+2HCl=FeCl2+H2

2H2O=2H2+O2(通电)

1.FeS+2HCl=FeCl2+H2S↑2.H2S+HgCl2=HgS↓+2HCl3.2H2S+SO2=3S↓+2H2O4.Hg+S=HgS5.S+O2=点燃=SO26.Na2SO3+2HCl=2N

Fe+O2=点燃=Fe3O44Fe+3O2==22Fe+3Cl2==2FeCl3Fe+2Fe2+)+H2气体————Fe+2HCl=FeCl2+H2Fe2O3+6H+==（2Fe3+)+3H2O(2F

1.AgNO3+NaCl=AgCl(沉淀)+NaNO32.Na2S+2HCl=H2S(气体)+2NaCl3.FeCl3+3NaOH=Fe(OH)3(沉淀)+3NaCl4.CaCO3+2HCl=CaCl

Zn+2HCl=ZnCl2+H2↑Zn是正二价Cl是负一价所以是ZnCl2

2Cu+O2=2CuO(等号上可能要加个反应条件“点燃”,你查一下）CuO+H2SO4(稀）=CuSO4+H2OCuSO4+BaCl2=BaSO4+CuCl22Mg+O2=2MgO(等号上可能要加个反

3Fe+2O2=点燃=Fe3O4Fe+2HCl===FeCl2+H2↑Fe+H2SO4===FeSO4+H2↑Fe+CuSO4==Cu+FeSO4Fe3O4+4CO=高温=3Fe+4CO2
