Why air is considered a homogeneous mixture?
In case of air, the majority of it contains nitrogen and oxygen. These gases cannot be readily differentiated from one another, and the air has a uniform composition of these gases throughout. Hence it is a homogenous mixture of various gases.
Why might air be referred to as a mixture?
Air is a mixture of Nitrogen (about 70%), Oxygen (about 20%), with small amounts of Carbon dioxide, smaller amounts of Carbon Monoxide and Helium, and traces of various other gases. It is a mixture because there is no chemical reaction between the components, and there are no chemical bonds between the components.
