Answer & Solution
Correct Answer
(D) i, ii,iii
Step-by-step Solution
Detailed explanation
(i) \(\mathrm{ZnO}, \mathrm{PbO}, \mathrm{Sb}_2 \mathrm{O}_3\) are amphoteric oxides that have the properties of both acids and bases. They have acidic properties against bases and basic properties against acids. (ii) \(\mathrm{CO}\) and \(\mathrm{NO}\) are neutral oxides since…
