In brief, yes. A mixture always contains two or more diverse chemical components that are not bounded chemically. Air is a mixture of gases. Approximately, air consists of : 1) Nitrogen N2 78% 2) Oxygen O2 20% 3) Noble gases 1% 4) Carbon dioxide CO2 0.03% 5) Water vapor H2O 0.97%. The water percentage is susceptible to territorial and seasonal variations. Other gases (sulphur and nitrogen oxides, for example) can also have some small contributions.

Question #137419

Is air a mixture?

Expert's answer

In brief, yes.

A mixture always contains two or more diverse chemical components that are not bounded chemically.

Air is a mixture of gases. Approximately, air consists of :

1) Nitrogen N₂ 78%

2) Oxygen O₂ 20%

3) Noble gases 1%

4) Carbon dioxide CO₂ 0.03%

5) Water vapor H₂O 0.97%.

The water percentage is susceptible to territorial and seasonal variations. Other gases (sulphur and nitrogen oxides, for example) can also have some small contributions.
