methane rapidly combines with oxygen to form carbon dioxide and water, releasing lots of heat. it's called combustion.
-------------------------------------------------------------------------
CH4 + 2O2 = CO2 + 2H2O + heat
methane
Methane and oxygen react according to the equation:CH4 + 2O2 -->CO2 + 2H2O Thus 1 mole of methane produces 2 moles of water. 25.9 g of water is 25.9/18 moles = 1.44 moles.So we must have started with 0.72 moles of methane, which is 0.72 x 16 g= 11.51 g of methane.
the percentage of these three gases in the air is as follows: Methane: 0.00002% Krypton: 0.00011% Hydrogen: 0.00005%
When methane is burned in a lime kiln, the waste gases are carbon dioxide and nitrogen because methane (CH4) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water vapor (H2O) during combustion. Nitrogen is also present in the air and is not directly involved in the combustion process, so it remains as a waste gas in the form of nitrogen (N2).
Methane gas settles down because methane gas is heavier than and is carried by the upward displacement of air. ---------------------------------------------- The density of methane is 0,717 g/L and the density of air is 1,2 g/L at 0 0C; consequently methane gas raise in the air.
Yes methane is lighter than air because it is less dense than air.
no i cannot
The fact that it oxidizes in air is a chemical property of methane.
Methane could be used used for preparation of toluene but not directly. First, methane is reacted with chlorine to give chloromethane and that chloromethane is reacted with AlCl3 to form CH3+ and AlCl4- . This is reacted with Benzene(C6H6). This yields toluene as CH3+ replaces a hydrogen from Benzene.

The atmosphere of Neptune is primarily composed of hydrogen, helium, and methane. The presence of methane in the atmosphere gives Neptune its blue color. The air quality of Neptune would not be breathable for humans due to the lack of oxygen and high concentrations of methane.
