General KnowledgeChemistry
- AThey produce basic oxides
- BThey produce acidic oxides
- CThey produce neutral oxides
- DThey provide hydroxides
Explanation
Non-metal oxides such as CO₂, SO₂ and NO₂ dissolve in water to form acids (carbonic, sulphurous, nitrous acid). Non-metals therefore produce acidic oxides, whereas metal oxides are generally basic.
