The charge of iron in FeO is 2+.
Iron has also the charge 3+ in other compounds.
The charge on the iron ion in Fe2O3 is +3. Iron (Fe) can form different ions, but in this case, each Fe ion carries a +3 charge to balance the -2 charge of the oxygen ions in the compound.
The valency of Fe in Fe2O3 is +3. This is because oxygen typically has a valency of -2 and there are three oxygen atoms present in Fe2O3, making the overall charge -6. To balance the charge, the iron (Fe) atoms must have a valency of +3.
To find the number of moles of Fe in 14.2 g of Fe2O3, we need to use the molar mass of Fe2O3 (molecular weight = 159.69 g/mol) and the ratio of Fe to Fe2O3. There are 2 moles of Fe in 1 mole of Fe2O3, so we find the moles of Fe in 14.2 g of Fe2O3 by: (14.2 g / 159.69 g/mol) * 2 = 0.249 moles of Fe.
If the moles of Fe2O3 are known, you would use the mole ratio from the balanced chemical equation for the reaction involving Fe2O3 and Fe. In the balanced equation, the mole ratio between Fe2O3 and Fe is 2:2, which simplifies to 1:1. This means that for every mole of Fe2O3, there is an equivalent mole of Fe.
The oxidation number of Fe in Fe2O3 (iron (III) oxide) is +3. This is because oxygen usually has an oxidation number of -2, and since there are three oxygen atoms in Fe2O3, the total oxidation number contributed by oxygen is -6. This means the Fe atoms must have a combined oxidation number of +6 to balance the charge, leading to an oxidation number of +3 for each Fe atom.

To calculate the Fe content in FeO, you need to consider that Fe accounts for about 71.85% of the FeO compound's molecular weight. For Fe2O3, each Fe atom accounts for about 69.94% of the compound's molecular weight. After determining the molecular weight of FeO and Fe2O3, you can find the Fe content by multiplying the molecular weight of Fe by the appropriate percentage.

Fe2O3
The first Fe represents an iron atom in the 0 oxidation state while the Fe in Fe2O3 represents iron ion in the +2 oxidation state
The reaction is:4 Fe + 3 O2= 2 Fe2O3
In the formula Fe2O3, the iron ion present is Fe3+. This means that each iron ion has a +3 charge, which balances with the -2 charge on each oxygen ion in the compound.
The balanced equation is 2Fe2O3 + 4Al ----> 2Al2O3 + 3Fe. The coefficient of Fe is 3.
Oxidation numbers in Fe2O3 are respectively: Fe => +3 and O => -2
