Solution

The correct option is C $F e_{2} O_{3}$
The molecular formula of ferric oxide (iron (III) oxide) is $F e_{2} O_{3}$ .
Ferric ion has $+ 3$ charge and oxide ion has $- 2$ charge. To maintain electrical neutrality, two ferric ions will combine with three oxide ions. The molecular formula of ferrous oxide (iron (II) oxide) is $F e O$ .
