What is the general nature of metal oxides?
Answer and explanation
Correct answer: Basic
The general chemical behaviour of metal oxides is basic. Many metal oxides react with acids in a neutralisation reaction to form a salt and water; for example, CuO + 2HCl → CuCl₂ + H₂O. This acid-neutralising behaviour supports option B. Although some metal oxides can be amphoteric and a few may show unusual behaviour, the expected general classification at this level is basic, not acidic, neutral or sweet.
