It is a Mixture
How could a man as such have pure tolerance? She was not as pure as a rose. Bill was as white as a pure albino.
Chemical materials (pure or impure) can be pollutants for waters, soils and air.
Pure air can be found in natural environments such as high mountain peaks, away from pollution sources. It is also common in remote rural areas with minimal human activity and industrialization. Indoor environments with good ventilation and air purification systems can also have pure air.
Pure air is homogeneous because all components are completely miscible.
Air is a mixture of different gases, including nitrogen, oxygen, carbon dioxide, and others, rather than a compound or element. It is not a pure substance but a combination of gases that makes up Earth's atmosphere.
The early morning Idaho mountain air in August smells clean and pure.

The pure nitrogen is a chemical element, gaseous at room temperature.
Air is considered a pure substance because it is a homogeneous mixture of gases, mainly nitrogen, oxygen, carbon dioxide, and trace amounts of other gases. Each component of air retains its unique chemical properties and cannot be separated by physical means without changing the composition of air.
The question looks strange and weird,but this what i can say,a mixture can never be pure,a pure substance can never be a mixture,though we can talk about ,like,pure air or something,but that is not in the strict chemical sense.
Air is a compound gas, but techically speaking it is definitely not a chemical substance. The main components of air are nitrogen (78% ) and oxygen (20.95%) and yes, those ARE chemical substances. Chemistry, as well as other sciences, requires you to be very specific with concepts and language.
reason for air is not pure
air is not pure
Yes, krypton is a pure chemical element. It is a noble gas found in the Earth's atmosphere and is typically isolated through fractional distillation of liquid air.
It's a chemical change - because the surface layer of the pure silver reacts with oxygen in the air - to form silver oxide.
