Model Answer
ZnO — amphoteric oxide; Na₂O — basic oxide; CO₂ — acidic oxide.
Explanation
Examiners expect all three categorised correctly in one line. ZnO reacts with both acids and bases (amphoteric); Na₂O is a metal oxide (basic); CO₂ is a non-metal oxide (acidic). No explanation needed for 1 mark.
