Answer 1

Answer:

the correct answer is option (C) Al2O3

Explanation:

atmosheric oxides react with both acids and bases to form salt and water . Example is aluminium oxide.

Answer 2

Example of an amphoteric oxide is (C) Al2O3

• Generally, all metal oxides are basic in nature but few exceptions like Aluminium show amphoteric nature.
• Aluminium can react with both acids and bases . This ability to form both basic as well as acidic oxide makes it an amphoteric oxide.
• This is because the electronegativity difference between Aluminium and that of Oxygen is very less. Hence, Aluminum can be called as Amphoteric oxide.
