In Fe2O3, iron (Fe) has an oxidation number of +3, and oxygen (O) has an oxidation number of -2. Iron's total oxidation number is +6 (since there are two iron atoms), balanced by the total oxidation number of -6 from the three oxygen atoms in the compound.
In Fe2O3, iron (Fe) has an oxidation number of +3, and oxygen (O) has an oxidation number of -2. Iron's oxidation number is determined by balancing the overall charge of the compound based on the known oxidation number of oxygen.
The oxidation number of Fe in Fe2O3 is +3 because oxygen typically has an oxidation number of -2 and there are 3 oxygen atoms for every 2 iron atoms in the compound, making the overall charge -6 for oxygen. To balance the charges, each iron atom must have a charge of +3.
In Iron III oxide (Fe2O3), iron has an oxidation number of +3, while oxygen has an oxidation number of -2. This allows for the overall compound to have a neutral charge.
In Fe2O3, iron (Fe) has an oxidation number of +3, while oxygen (O) has an oxidation number of -2. This means that each Fe atom contributes +3 to the compound, and each O atom contributes -2.
In the compound Fe2O3, iron has an oxidation number of +3 because oxygen typically has an oxidation number of -2. Iron needs two atoms of oxygen to balance its +6 oxidation state, hence the compound with the formula Fe2O3.
