Which of the following oxides is most acidic in nature ?
1 BaO
2 CaO
3 BeO
4 MgO
Explanation:
Down the group basic nature increases in alkaline earth metals. Hence, BeO is more acidic.

Identify the element that forms amphoteric oxide
1 Carbon
2 Zinc
3 Calcium
4 Sulphur
Explanation:
Zn (zinc) element of forms amphoteric oxide i.e. ZnO. This oxide reacts with both acids and bases, exhibiting a dual behaviour. They show characteristics of both acidic as well as basic oxides. Following reactions are given by ZnO \({\rm{ZnO + 2HCl}} \to {\rm{ZnC}}{{\rm{l}}_{\rm{2}}}{\rm{ + }}{{\rm{H}}_{\rm{2}}}{\rm{O}}\) \({\rm{ZnO + 2NaOH}} \to {\rm{N}}{{\rm{a}}_{\rm{2}}}{\rm{Zn}}{{\rm{O}}_{\rm{2}}}{\rm{ + }}{{\rm{H}}_{\rm{2}}}{\rm{O}}\) Note: Among oxides, CO is netural, CaO is basic and \({\rm{S}}{{\rm{O}}_{\rm{2}}}\) is acidic in nature.
