Which of the following sets mismatched regarding the nature of oxides?
(A) Neutral oxides - \(CO_{2},NO\)
(B) Amphoteric oxides - BeO,\(Al_{2}O_{3}\)
(C) Acidic oxides - \(Cl_{2}O_{7},NO_{2}\)
(D) Basic oxides - \(Na_{2}O,BaO\)

Why is Al_(2)O_(3) amphoteric oxide?

Gallium oxide (Ga_(2)O_(3)) is an amphoteric oxide.

Mn_2 O_3 is acidic/basic oxide.

Mn_(2)O_(7) is an acidic oxide, why ?

Which of the following sequence correctly represents the decreasing acidic nature of oxides? (А) \(Li_{2}O > BeO > B_{2}O_{3} > CO_{2}>N_{2}O_{3}\) (В) \(N_{2}O_{3} > CO_{2} > B_{2}O_{3} > BeO>Li_{2}O\) (с) \(CO_{2} > N_{2}O_{3} > B_{2}O_{3} > BeO>Li_{2}O\) (D) \(B_{2}O_{3} > CO_{2} > N_{2}O_{3} > Li_{2}O>BeO\)

Which of the following statements is//are correct? I. B_(2)O_(3) is an acidic oxide II. Ga_(2)O_(3) and Al_(2)O_(3) are amphoteric oxides. III. In_(2)O_(3) and tl_(2)O_(3) are basic oxides.
