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

Just did that and I have the same amount of elements on each side so O guess it's balanced! Thanks :D

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
