Question

Give three reasons why air is a mixture and not a compound​??​

Answer 1

Answer:

1. Air does not have a formula like a mixture, while compounds have a fixed formula.

2. When air is formed by gases, there is no energy change.

2. Properties of air are variable and subjective to time and place.

4. Components of air can be physically separated.

Answer 2

Answer:

Air is a mixture not a compound because,

• Air can be separated into its constituents such as oxygen, nitrogen etc. by fractional distillation of liquid air.
• Air shows the properties of all the gases present in it.
• For example: Air supports combustion because of oxygen present in air.
