(i) Oxidation state of K in KO₂:

KO₂ is potassium superoxide.

O₂⁻ is superoxide ion, charge = –1.

K⁺ + O₂⁻ → Oxidation state of K = +1 → x = 1

(ii) Formal charge on carbon in CO:

CO Lewis structure: C≡O with lone pair on C and O

Formal charge formula: FC = valence – nonbonding – ½(bonding)

Carbon: 4 – 2 – 3 = –1 → magnitude = 1 → y = 1

(iii) Formal charge on oxygen in CO:

Oxygen: 6 – 2 – 3 = +1 → magnitude = 1 → z = 1
