Question

Assertion(A): The air is a compound made up of oxygen, nitrogen, argon, carbon dioxide and
water vapour in a fixed proportion according to their masses.
Reason(R): A compound is a substance whose composition of the components is fixed because
they combine together in a fixed ratio according to their masses

Answer 1

Answer:

The air is a compound made up of oxygen, nitrogen, argon, carbon dioxide and

water vapour in a fixed proportion according to their masses.

Answer 2

Air is a combination, not a substance.

Air, unlike mixtures, does not have a defined formula, whereas compounds have.

Fractional distillation of liquid air can separate it into its constituents, such as nitrogen, oxygen, argon, and carbon dioxide.

The properties of all the gases in the atmosphere can be seen in the air.

A compound, on the other hand, is a substance formed by combining two or more chemical ingredients.

As a result, the statement is untrue, while the reason is correct.
