  1. 2 NH3 + 2 Na > 2 NaNH2 + H2

    (This looks weird. Could you double check? I don't think there's Na NH2...)

    BaCl2 + Na2SO4 > BaSO4 + 2 NaCl

    (I believe you have an error on #2... I believe it is BaSO4)

    SO2+ 2 NaOH > Na2 SO3 +  H2O(L)

    2 Al+ 3 H2SO4 > Al2(SO4)3 +3 H2


  2. 2NH3+2Na--->2NaNH2+H2

    BaCl2+Na2SO4------>BaSO4+2NaCl

    SO2+2NaOH---------->Na2SO3+H2O

    2Al+3H2SO4-------->Al2(SO4)3+3H2

  3. 2NH3 + 2Na --> 2NaNH2 + H2

    BaCl2 + Na2SO4 --> BaSO4 + 2NaCl

    SO2 + 2NaOH --> Na2SO3 + H2O

    2Al + 3H2SO4 --> Al2(SO4)3 + 3H2
