Answer 2

Answer: Air is a mixture and water is a compound because:

Explanation:

(i) The atoms in air are loosely packed (vander waals force is low) , So many gases can be accommodated in making equal equilibrium with liquids.

But,

Water has strong forces between atoms (high vander waals forces), So it remains as a compound.

(ii) Water has hydrogen bonding whereas gas doesn't.
