What kind of gas is a fart?

Answer 1

What a straightforward way to ask a question! By the smell of most of them there must be more than methane there. I believe that there is also sulphuretted hydrogen (hydrogen sulphide) which smells like rotten eggs.

You could have a crack at 'flatulence' in wikipedia.

Answer 2

Methane is sometimes (in humans) one of the gases, but nitrogen is the greatest, and some hydrogen. This is determined by the individual's intestinal flora. Occasional sulfur-containing compounds give the most offensive smells.

Bovines with their multi-stomach process and an active internal flora for re-digesting food, produce large quantities of methane.

Answer 4

NASA and Air Force scientists actually had several experiments of capturing "flatus" to analyze it. We've known for a long time that it is primarily methane, which is flammable; the fear was that farts in a space suit or spacecraft might spark an explosion.

As expected, flatus is primarily methane, with considerable hydrogen sulfide mixed in, with various ketones and esters that varied from person to person. The methane concentration could never become explosive, so NASA stopped worrying about that and concentrated on developing air purification systems that could remove the hydrogen sulfides, which is the stinky part.

Answer 5

methane that's why it catches fire when you light it.

However, the smell is largely due to hydrogen sulfide.
