+3 for Fe; -2 for O
100 will be oxidation no.in Fe2O3.
study island answer is +3 -2
study island answer is +3 -2
it is +2 it is also done by causing rust
The oxidation number of iron in this compound is 3. The oxidation numbers of the total oxygen atoms and the total iron atoms must be the same in a neutral compound. There are three oxygen atoms, giving a total for oxygen of 3 X 2 = 6. There are only two iron atoms; therefore, each one must have an oxidation number of 6/2 = 3.
100 will be oxidation no.in Fe2O3.
Oxidation numbers in Fe2O3 are respectively: Fe => +3 and O => -2
Usually, oxygen has an oxidation of -2 (that is unless in a compound with peroxides or halogens).

Fe2O3 +3 for each Fe -2 for each O
No, Fe2O3 is ionic
This may best be demonstrated by example: Here are two forms (read: oxidation numbers) of iron, as FeO and Fe2O3. Because we know oxygen has a -2 charge per atom, the oxidation number of Fe in FeO is II. As for Fe2O3, we know that the oxidation number of Fe is III; there is no charge on the compound, so the two iron molecules must equally offset the -6 charge from the three oxygen atoms. Oxidation numbers are written as roman numerals. You would write these two forms of iron oxide as iron(II) oxide and iron(III) oxide, respectively. Oxidation states are the (+) or (-) charges written as a superscript.
That is an oxidation reaction (I am translating the numbers into subscripts) which in this case is also called rusting.
FeO is iron II oxide or ferrous oxide. In this compound iron forms a 2+ ion which combines with oxygen(which forms a 2- ion) in a 1:1 ratio Fe2O3 is iron III oxide or ferric oxide. In this compound iron forms a 3+ ion which combine with oxygen (again a 2- ion) in a 2:3 ratio. In Fe2O3 iron is in its highest oxidation state. FeO is black, Fe2O3 is red. Fe2O3 is more common. FeO is a better conductor than Fe2O3.
