Methane (/ËmÉÎ¸eÉªn/ or /ËmiËÎ¸eÉªn/) is a chemical compound with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen).ethane can be produced by hydrogenating carbon dioxide through the Sabatier process. Methane is also a side product of the hydrogenation of carbon monoxide in the Fischer-Tropsch process. This technology is practiced on a large scale to produce longer chain molecules than methane.
== From Pisgahchemist: The catch is that there are NO molecules of H2CO3 in aqueous solution. What we call carbonic acid is actually CO2 dissolved in water in equilibrium with H+ and HCO3^-. Carbonic acid is a weak acid, and so you might think that there would be nonionized H2CO3 molecules. That simply isn't the case.
