Fe+3 SO3-2 ------> these are the ions and their charges. Sulfite's charge is -2 and Iron's charge is +3 (you know this because of the (III)
Fe+3 Fe+3 SO3-2 SO3-2 SO3-2 ------> the charges have to add up to zero, so two +3 Fe ions equal +6 and three -2 Sulfite ions equal -6.
Fe2(SO3)3 -----> simplify
Iron III has a charge of +3, and sulfite has a charge of -2, so balance the charges, they bond as Fe2(SO3)3
Fe2(SO3)3
Fe2(SO3)3 Ferric sulfite or Iron III sulfite.Absorbs oxygen from the air to form iron III sulfate.
The chemical formula for the compound formed between iron(III) and iodine is FeI3 (iron(iii) iodide).
FeCl3
I think you mean either:- FeSO4 Iron(II) sulfate or ferrous sulfate Fe2(SO4)3 Iron(III) sulfate or ferric sulfate FeSO3 iron(II) sulfite or ferrous sulfite Fe2(SO3)3 iron(III) sulfite or ferric sulfite (I believe this compound is theoretical - the sulfite ion reduces the Fe3+ to Fe2+ )

Fe2(SO3)3 Ferric sulfite or Iron III sulfite.Absorbs oxygen from the air to form iron III sulfate.
Mn2(SO3)3
The chemical formula of iron(III) and selenium is Fe2Se3 - iron(III) selenide.
The chemical formula of iron(III) chlorite is Fe(ClO2)3.
