Answer to Question #266682 in Physical Chemistry for Hoor

Question

We know that air is a mixture and a compound because?

Answer 1

When gas are mixed to form air there is no major heat change.

Air can be separated into its components like Nitrogen, Oxygen, Argon and Carbon- dioxide by physical means ( Fractional distillation)

All properties are similar to those of constituent elements

Air does not have a fixed formula

Air cannot be said to be a compound, because the molecules making air are not chemically combined, neither air is made of elements than are chemically combined but it's made of mixer of gases.
