air is homogeneous
The pure nitrogen is a chemical element, gaseous at room temperature.
It depends. You can have a gaseous mixture such as air, which would be a homogeneous mixture. But a single gas such as oxygen or methane would be a pure substance.
City air is a heterogeneous mixture because it contains a variety of different gases, particles, and pollutants that are not evenly distributed throughout the air.
is heterogenous because it is composed of many different gases. To be homogenous it would have to be composed of a single gas.
Air, like other phases that contain only gas, is usually a homogeneous mixture. If the air contains solid particulates, such as soot, or liquid particulates, such as rain drops, the air is a heterogeneous mixture.
Pure air is homogeneous because all components are completely miscible.
No. It will be a homogeneous mixture of gases.
Air is a homogeneous mixture.

pure air is homogeneous but dusty air is heterogeneous

Heterogeneous: Deformities, a mixture. Eg. Salad dressing Homogeneous: Pure no deformities in it. Eg. Air and other compounds

CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.
