http://www.bionomicfuel.com/methane-gas-can-be-harmful-if-not-contained-or-burned/ che out this site, maybe this could help further answer any of your questions on methane gas [:
Methane is found in the Earth's crust. It is also produced by certain microbes and by cows during their digestive process.
reacted out with oxygen as oxygen levels rose.
CH3F - monofluoro methane or fluoro methane CH2F2 - difluoro methane CHF3 - trifluoroo methane CF4 - tetrafluoro methane
Percentage of hydrogen in methane is 25%. Percentage of hydrogen = mass of hydrogen/mass of methane x 100 mass of hydrogen = 1 x 4= 4 and mass of carbon = 12. Since methane has 4 hydrogen atoms and one carbon atom therefore mass of methane = 16 Percentage of hydrogen = 4/16 x 100 =25
If you are asking how much pressure you would have to compress methane to in order to liquify it at room temperature, the answer is that methane won't liquify at room temperature. The critical temperature for methane is -87.2 degrees centigrade. Above that temperature it will not liquify no matter how much pressure you apply. At -82.7 degrees centigrade it would take a pressure of 45.96 bar to get it to liquify. See: http://www.chem.purdue.edu/gchelp/liquids/critical.html
methane is dangerous to our earth it can cause damage to our solar radiation that protected and minimize the heat of the sun. with this meathane it can cause harmful.
it doesnt
A relatively thin band of gasses surrounds Earth. This is the atmosphere. 78% of Earth's atmosphere is Nitrogen and 21% is Oxygen. The remaining 1%, known as "trace gases", consists of argon, CO2, water vapor, hydrogen, helium, methane, neon, etc.
Methane
methane gas
Methane is just a general word for the substance, while methane ice is frozen methane, in it's solid form. It has to be quite cold for this to happen, it's a gas at normal earth temperatures and pressures.
scientests have been finding out that the earth is warming up by methane
Methane is found in the Earth's crust. It is also produced by certain microbes and by cows during their digestive process.
methane gas and flooding are to main reasons
Methane is a greenhouse gas and it absorbs infrared radiation that is remitted from the earth. As it absorbs the radiation it is stopping it from being re-radiated to space thus warming the earth.
Petroleum, coal, and methane.
There was a lot of methane.
