Is metahne really a gas?
117258
yes \n\n CH4, colorless, odorless, gaseous saturated hydrocarbon; the simplest alkane. It is less dense than air, melts at −184°C, and boils at −161.4°C. It is combustible and can form explosive mixtures with air. Methane occurs naturally as the principal component of natural gas; it is formed by the decomposition of plant and animal matter. When this decomposition occurs underwater in swamps and marshes, marsh gas is released. The firedamp of coal mines is chiefly methane

You may have tapped into a new source of natural gas.

The miracle you need has been known to us for many years...it's called:\n\nBEANO\n\nIt's an anti-gas product that works wonders, or Gas-X works.

They're gases (although butane forms a liquid under a little pressure) and the rest are liquids, at room temperature. Pentane is highly volatile, though.

Dear Somat, wow that is a significant question.\n\nUnfortunately the answer in numbers of molecules and by sheer tonnage is carbon dioxide, one of the so-called greenhouse gasses.\n\nWe create it directly by breathing, raising livestock, farming and most by using fossil fuels.

Its a mixture of hydrocarbons. It doesn not have a name because it is not composed of one compound.

Yes - methane gas is a by-product of your digestive system - methane is flammable. Lighting it can be entertaining for some - but it can sometimes have painful consequences - such as burning hair and skin in and around the immediate area

Any gas (CO2, N2, whatever) that doesn't abide by the Ideal Gas Law....\n\nIDEAL gases are just that, IDEALS, and they abide by PV=nRT.\n \nIn the real world, gases abide by a more modified version of this equation.  Hence the term, "real" gases.

It really means you are fun and nasty...\nBut basically yes... \nRead the composition here:\nNitrogen is the primary gas released. Methane and hydrogen, lesser components, are flammable, and so flatulence is susceptible to catching fire. Not all humans produce flatus that contains methane. For example, in one study of the feces of nine adults, only five of the samples contained bacteria capable of producing methane[5]. Similar results are found in samples of gas obtained from within the rectum. The gas released during a flatus event frequently has a foul odor which mainly results from low molecular weight fatty acids such as butyric acid (rancid butter smell) and reduced sulfur compounds such as hydrogen sulfide (rotten egg smell) and carbonyl sulfide that are the result of protein breakdown. The incidence of odoriferous compounds in flatus increases from herbivores, such as cattle, to omnivores to carnivorous species, such as cats. Flatulence odor can also occur when there is a number of bacteria and/or feces in the anus while being expelled. A small amount of solid or liquid fecal matter in fine particulate aerosol form may also be expelled, and included, along with flatulence.

I have gas - does that count?

CH4 is given to the abreviated name methene, (methanol). It is actually metholethaline. or as we like to cll it on the Hazmat squad, methandeathanol.  Very leathal in large quantities.

Natural Gas like methane CH4 and ethane, butane, propane ..\n\nCO2, H2O .. \n\nvolcanic gases : water vapor, carbon dioxide, sulfur either as sulfur dioxide (high-temperature volcanic gases) or hydrogen sulfide (low-temperature volcanic gases), nitrogen, argon, helium, neon, methane, carbon monoxide and hydrogen. Other compounds detected in volcanic gases are oxygen (meteoric), HCl, HF, HBr. Exotic trace compounds include methyl mercury, halocarbons (including CFCs), and halogen oxide radicals.\n\nsorry for not giving a complete answer but some are better than nothing !!!

the natural gas ( mostly methane CH4) is odorless, when they extract it from underground, it have some unwanted particles. they take it to a facility called Gas refinement to purify it. in doing so they also add small amounts of sulfur Di oxide(SO2) to give it some odor so it can be detected and to prevent explosions.\nCO (carbon monoxide) however is produced right where you are( any indoor fire that doesn't burn properly) so there is no chance to add something to it. they are some detectors to detect CO and they are good from personal use, but they are not to sensitive and might give you a false alarm by detecting CO2 (which is in the air that you breath out)

Ack... Munir got here before I did agian.  A agree with Munir!  Volume of any gas at STP is 22.4L.

Here you are (nice circles and atoms and stuff):\n\nhttp://www.uwgb.edu/dutchs/PETROLGY/ScaleAtomsCsRn.HTM

Solid or gaseous, depending on what the question means when refering to non-metals:  There are 11 gases total out of the entire table (6 are nobel gases) and only 2 liquids..mercury and bromine.  The true non-metals comprise only 7 elements, and only 3 of those (hydrogen, nitrogen, and oxygen) are gases.  If you takea  looser definition of non-metals, which includes the true nonmetals plus the halogens and noble gases, the the answer is gaseous.  From the wording of the question, I would think they were trying to get you to say gaseous.

No, they are filled with an inert gas, such as argon.
