3 ημέρες πριν · Methane is a hydrocarbon that is a gas at room temperature (20°C). Its molecular formula is CH 4, so it has one carbon atom and four hydrogen atoms per molecule. It is often found as the main part of natural gas. Methane is a greenhouse gas 22 times more effective than carbon dioxide.

Methane is a greenhouse gas with a global warming potential of 22 (meaning that it has 22 times the warming ability of carbon dioxide). Methane results from the decomposition of certain organic matters in the absence of oxygen .
Figure 8: The structure of methane, CH 4 . This regular tetrahedral structure is explained in the VSEPR theory of molecular shape by supposing that the four pairs of bonding electrons (represented by the gray clouds) adopt positions that minimize their mutual repulsion.
