Metal oxide + Acid → Salt + Water
(e.g., CuO + H₂SO₄ → CuSO₄ + H₂O)
Source: Acids, Bases and Salts, Chapter 2
The examiner expects the general word equation and ideally one example with a chemical equation. "Metal oxide + Acid → Salt + Water" is the core answer and must be written exactly in this form. The example strengthens the answer but the general equation alone is sufficient for 1 mark.
