Why is air classified as a mixture?

Answer 1

The best reason I can think of for why we believe that air is a mixture is that freezing air slowly yields different liquids at different temperatures. Liquid nitrogen has a different boiling point than liquid oxygen. They also freeze at different temperatures. If air were only 1 compound, then air in its entirety would have a single boiling point and a single freezing point.

Answer 2

Air is classified as a mixture because it is composed of various gases such as nitrogen, oxygen, carbon dioxide, and others, each retaining their individual properties and can be separated through physical means like filtration or distillation. It does not have a fixed composition and can vary depending on the location and environmental conditions.

Answer 3

Air is called a mixture because air contain not only one element or one compound; air contain many elements and compounds: nitrogen, oxygen, argon, carbon dioxide, water vapours, helium, neon, krypton xenon, ozone, radon, pollutants.

Answer 4

Air is called a mixture because its made up of gas and a small amount of water.You can tell this by when its foggy because there is more dew on the grass than on a regular morning.It also may possibly freeze the grass you step on.Thats my answer for why air is called a mixture

Answer 5

Air is a mixture because in air so many gases are present and they are seperately moving and not bonded by chemical bond.

Answer 6

Because the gases in the atmosphere are NOT combined to make any other chemical.

Answer 7

because it contains several gasses: oxygen, nitrogen, carbon dioxide, and several others. The mix of these is "air"

Answer 8

Because it can be separated by physical methods.

Answer 9

Air is a combination of mostly Nitrogen, some Oxygen, a little Carbon Dioxide, and a very, very small amount of other gasses

Answer 10
