DifferBetween Difference Between FeO and Fe2O3

Difference Between FeO and Fe2O3. 3119. 170. The key difference between FeO and Fe2O3 is that FeO has iron in +2 oxidations state, whereas Fe2O3 has iron in +3 oxidation state. FeO is the chemical formula of iron (II) oxide while Fe2O3 is the chemical formula of iron (III) oxide. ... Are Fe2O3 and FeO the same compounds?

How to calculate FeO from Fe2O3T? - ResearchGate

Mar 23, 2017 The reduction of Fe2O3 by H2 was conducted in a thermogravimetric analyzer at 973–1172 K. The phase analysis of reduction products in different reduction stages illustrated that Fe2O3 → Fe3O4 and Fe3O4 → FeO proceed simultaneously; hence, the reduction process is a two-step reaction, in the sequence of Fe2O3 → FeO and FeO → Fe.

These results indicate that the average state of Fe atoms in the B-Fe 7 S 8 /FeS 2 electrocatalysts is between +2 and +3, same as that obtained from their XPS spectra.

FeO converted to Fe2O3? - Answers

How many atoms of oxygen are in FeO? Since atoms are not divisible into halves, we should instead say that in the ferric molecule there are 3 oxygen atoms for every 2 iron atoms. Thus, (Fe is the symbol for an iron atom, and O is the symbol for an oxygen atom) the ferrous oxide molecule is FeO, and the ferric oxide molecule is Fe2O3.
