The Correct Option is C
Solution and Explanation
Group 13 elements have the general oxidation state of +3. Oxygen has a -2 oxidation state.
To balance charges: $2 \times (+3) = 3 \times (-2)$ ⇒ compound formula = $M_2O_3$
Therefore, the element to oxygen ratio = 2 : 3
To balance charges: $2 \times (+3) = 3 \times (-2)$ ⇒ compound formula = $M_2O_3$
Therefore, the element to oxygen ratio = 2 : 3
