Question

thx...for the answer but in the book the question statment and the answer is different
in question is written fe(iii) oxide and in answer it is written fe(ii iii)oxide....so what should I follow
in my book the question is

Q1-write a balanced chemical equation for the following

A-iron fillings react with steam to produce soils iron(iii) oxide and hydrogen gass
in the answer instead of iron(iii) they have written iron(ii iii)(which is ferric ferrous oxide)

so is the answer in the book wrong?

when I searched online.....in the answer some used iron(iii)oxide(fe2O3)
some used iron(ii)oxide(feO)
and some iron (ii iii) oxide(fe3O4)

so what oxidation state of iron should I use.....plss tell... urgent

Answer 1

It is given correct in your book. and answers you got online are correct as well. reason for this is variable valency of iron.

if no condition are mentioned you can write any of all.

but most preferred answer is Fe3O4
