What gases are present in air?

Answer 1

Air is primarily composed of nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include argon, carbon dioxide, neon, helium, and methane. These gases make up the Earth's atmosphere and play a crucial role in supporting life on our planet.

Answer 2

Nitrogen, N2 78.08

Oxygen, O2 20.95

Argon, Ar 0.93

Carbon dioxide, CO2 0.033

Neon, Ne 0.0018

Helium, He 0.00052

Methane, CH4 0.0002

Krypton, Kr 0.00011

Nitrogen(I) oxide, N2O 0.00005

Hydrogen, H2 0.00005

Xenon, Xe 0.0000087

Ozone, O3 0.000001

Answer 3

Oxygen is the main gas present in air.

Atmospheric chemistry is composed primarily of nitrogen (N2) at about 78%, almost 21% is oxygen (O2), less that a percent is argon (AR), and the remainder is composed of trace amounts of carbon dioxide (CO2), neon (Ne), helium (He), methane (CH4), krypton (Kr), and hydrogen (H2), and isotopes of all of these. Water vapor generally makes up about 1%, but that level can vary. There can also be a number of pollutants in the air at any one time such as carbon monoxide, cadmium, benzene, arsenic, cyanide, Mercury, and ozone as well as a nearly limitless list of other contaminants.

Answer 4

The main gases present in air are nitrogen (about 78%), oxygen (about 21%), and trace amounts of argon, carbon dioxide, and other gases. Water vapor is also present in varying amounts depending on the location and weather conditions.

Answer 5

78% nitrogen

21% oxygen

almost 1% argon

the rest .000000001% is a bunch of other gases

Answer 6

Nitrogen- 74%

Oxygen- 21%

Hydrogen- 4%

Other gases (Argon,Neon, Helium..)- 1%

Answer 7

Basically Nitrogen, Oxygen, Carbon Dioxide and other gases in very small quantities.

Answer 8

oxygen, nitrogen and carbon dioxide are also essential for human being in different aspects.
