What is the most common gas in the universe?

Question

relevant answers please

Answer 1

Human gas. 29 billion people fart an average of 5 times a day.

Answer 2

Hydrogen (Latin: 'hydrogenium', from Ancient Greek: hydro: "water" and genes: "forming") is a chemical element in the periodic table that has the symbol H and atomic number 1. At standard temperature and pressure it is a colorless, odorless, nonmetallic, univalent, tasteless, highly flammable diatomic gas (H2). With an atomic mass of just 1.00794 g/mol, hydrogen is the lightest element of the universe. It is also the most abundant, constituting roughly 75% of all the universe's elemental matter.[1] It is present in water, all organic compounds, and in all living organisms. Hydrogen is able to react chemically with most other elements. Stars in their main sequence are overwhelmingly composed of hydrogen in its plasma state. The element is currently used primarily in fossil fuel upgrading. Other uses include as a lifting gas, as an alternative fuel (see Hydrogen economy), and more recently as a power source in fuel cells.

Answer 3

HYDROGEN
it accounts to 71% of all gases in the universe



When the Universe was formed in the Big Bang, the resulting elemental matter was about three quarters hydrogen, one quarter helium, and a few parts-per-billion of lithium (by weight). http://imagine.gsfc.nasa.gov/docs/science/mysteries_l2/composition.html

(When I say 'elemental matter', I am referring to matter made of the common chemical elements we see around us. However, one of the great mysteries of astrophysics is, we don't know what most of the Universe is made of. Between 90% and 99% of the mass of the Universe seems to be completely unknown. This 'dark matter' has so far been detected only gravitationally: galaxies and clusters of galaxies seem to be heavier (or at least have more gravitational attraction) than can be explained by summing up all the stars and gas clouds we see.

Some of this matter coalesced into galaxies and stars, although much remained as gas. As time went on, stars burned some of their hydrogen to heavier elements. These stars occasionally released their material (as winds, in supernova explosions, and in other events) so that it combined with the remaining gas, and formed new stars, and so on. All material on Earth except for the hydrogen (such as that in water), helium, and lithium is this burned material. Our Sun, and most of the stars you can see in the night sky, are later-generation stars, and we can see the material burned by earlier stars in their atmospheres. http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/961112a.html

Only a few percent of the original hydrogen and helium in the Universe has been burned this way. Most of it is still around, and so the elemental matter of the Universe is still about three quarters hydrogen, which is primarily in the form of clouds of gas and stars.

Answer 4

Methane Gas

Answer 5

Its Oxygen, A nonmetallic bivalent element that is normally a colourless odourless tasteless nonflammable diatomic gas; constitutes 21 percent of the atmosphere by volume; the most abundant element in the earth's crust

Answer 6

Hydrogen

Nitrogen

Answer 8

Hydrogen and Hilium

Answer 9

Hydrogen and associated isotopes, all the stars and stuff are made out of it.

Answer 10

Hydrogen it is the simplest element of one proton and one electron.
