which atmospheric gas is not flammable?

Answer 1

Nitrogen and carbon dioxide are the main atmospheric gasses. They are not flammable.

Answer 2

Nitrogen, which makes up 78% of the air mixture, is certainly not flammable. 21% is usually attibuted to oxygen, which you probably know IS quite flammable. The other 1% is made up of other gasses in lesser abundance. Among those are carbon dioxide and argon, both of which are non-flammable.

Answer 3

actually none of the gases are flammable.
however, oxygen make combustion possible.
argon, nitrogen(in gas form), carbon dioxide are NOT flammable-(these are the most common gases that make up the atmosphere; however, they are not all of them )

Answer 4

Definitely not oxygen...hehe

I believe that nitrogen is not flammable. But there looks to be more as well. nitrogen is the most abundant atmospheric gas that is nonflammable.

Answer 5

atmospheric gas (¦at·mə¦sfir·ik ′gas)
(meteorology) One of the constituents of air, which is a gaseous mixture primarily of nitrogen, oxygen, argon, carbon dioxide, water vapor, ozone, neon, helium, krypton, methane, hydrogen, and nitrous oxide.


--------------------------------------------------------------------------------
Helium is a non-flammable, colorless, odorless gas. Its concentration in the atmosphere is 5-50 ppm.

Answer 6

carbon dioxide

Answer 7

Carbon Dioxide, that is why they use it in fire extenguishers!
