What type of gas can we breathe?

Answer 1

Nitrogen and oxygen are the two most important gases. They comprise about 78 and 21 % of the air respectively. There are also variable amounts of water vapour, about 0.93% argon, 0.04% carbon dioxide and trace amounts of other gases, both natural and polluting.

nitrogen - 78.084%

oxygen - 20.946%

argon - 0.934%

water vapour - 0.4%

carbon dioxide - 0.04%

neon - 0.01818%

helium - 0.000524%

methane - 0.000179%

krypton - 0.000114%

hydrogen - 0.000055%

nitrous oxide - 0.00003%

carbon monoxide - 0.00001%

xenon - 0.000009%

ozone - 0.000007%

nitrogen dioxide - 0.000002%

iodine - 0.000001%

ammonia - trace
There are several gases present in the atmosphere

• Nitrogen-78%
• Oxygen-21%
• Carbon dioxide-0.03%
• Other gases- traces

Answer 2

There are many gases in the atmosphere, mainly consisting of Nitrogen (N2, 78%), Oxygen (O2, 21%), and Argon (1%, Ar). There are also traces and the other noble gases, Neon, Helium, Krypton and Xenon. Hydrogen is present, but usually floats away due to its very low mass and density. There is also the greenhouse gases, including Carbon Dioxide (370 parts per million, CO2), Methane (CH4), Nitrous Oxide (N2O), Water Vapour (H2O), and Ozone (O3).

Answer 3

Human Beings breathe in only oxygen. So I suppose there is just one gas, that is, Oxygen which is 21% by volume.

Answer 4

the thermosphere, merashere, stratosphere, and thophere.

Answer 5

We can inhale nitrogen and oxygen. Nitrogen is the most common gas in the earth's atmosphere. If we inhale air pollution and greenhouse gases, it can cause lung cancer or pneumonia.
