Explanation:

Air is considered a mixture because of the following reasons : Heat and light, etc., are neither given out nor absorbed when air is prepared by mixing the required proportions of oxygen, nitrogen, carbon dioxide, argon, water vapour, etc.

Answer 2

air has many gases like oxygen, nitrogen, carbon dioxide, etc which are mixed together. these gases do not form compounds. they retain their own properties and can be separated by only physical means. therefore air is said to be a mixture.
