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.
Aqueous carbon dioxide, CO2 (aq), reacts with water forming carbonic acid, H2CO3 (aq). Carbonic acid may loose protons to form bicarbonate, HCO3- , and carbonate, CO32-. In this case the proton is liberated to the water, decreasing pH.
