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.
H2O + CO2 <---> H2CO3. H2CO3 is known as carbonic acid, and is the reason tap water is slightly acidic. The more CO2 dissolved into the water, the more acidic the water gets. pH can get as low as pH 5, though usually it is just over pH6.
