    I need some help balancing this equation
    Fe+H2SO4------> FeSO4+Fe[SO4]3+H2O+6SO2

    my best guess was

    4Fe+12H2SO4------>3FeSO4+Fe[SO4]3+12H2O+6SO2

    but I'm not sure so I would really apprecatie if someone told me if I'm right or wrong and show me the balanced equation.
    thanks in advance

    That looks like the combination of two different reactions.

    More info. Needed here.

    Looks good to me - all the elements balance OK.

    Just check if you have the same amount of lements on each side

    it is just adding concentrated sulphuric acid to iron as far as I know that should be the product of the equation

    Fe[SO4]3


    What is the oxidation number on this iron?

    The products of iron II and concentrated sulfuric acid are..

    FeSO4 + H2) + SO2

    That other product does not fit according to my sources.

    I'm not sure about the oxidation number but have you tried to check iron ||| ?

    Fe2(SO4)3

    Would be the iron III oxidation number and correct link up with sulfate.

    Fe[SO4]3

    This would not result from either iron II or iron III
