Question
The name of Fe2O3 : Question 13Select one:a.Iron (IV) oxideb.Iron oxidec.Iron (III) oxided.Iron (II) oxide
Solution
The name of Fe2O3 is Iron (III) oxide.
Here's why:
The Roman numeral in the name of a compound represents the charge of the cation. In this case, we have Fe2O3.
Iron (Fe) can have multiple charges, but oxygen (O) always has a charge of -2.
Since we have 3 oxygen atoms, the total charge contributed by oxygen is -6.
To balance this, the total charge from the two iron atoms must be +6.
Therefore, each iron atom must have a charge of +3.
So, the correct name is Iron (III) oxide.
