Web5 apr. 2024 · The EPA has identified three major groups of high Global Warming Potential (GWP) gases: (1) hydrofluorocarbons (HFCs), (2) perfluoro-carbons (PFCs), and (3) sulfur hexafluoride (SF6). These represent the most potent greenhouse gases; and the PFCs and SF6 also have extremely long atmospheric lifetimes —up to 23,900 years. WebL' équivalent CO2 (abréviations : eqCO 2, éq. CO 2, CO 2 e ou CO 2 -eq) d'une émission de gaz à effet de serre est la quantité de dioxyde de carbone (CO 2) qui provoquerait le même forçage radiatif cumulé sur une période de temps donnée, c'est-à-dire qui aurait la même capacité à retenir le rayonnement solaire. brewton federal credit union

Methane is a chemical compound with the chemical formula CH4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing … Meer weergeven Methane is a tetrahedral molecule with four equivalent C–H bonds. Its electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H. The lowest … Meer weergeven Methane is used in industrial chemical processes and may be transported as a refrigerated liquid (liquefied natural gas, or LNG). While leaks from a refrigerated liquid … Meer weergeven Methane was discovered and isolated by Alessandro Volta between 1776 and 1778 when studying marsh gas from Lake Maggiore. … Meer weergeven Etymologically, the word methane is coined from the chemical suffix "-ane", which denotes substances belonging to the alkane … Meer weergeven The primary chemical reactions of methane are combustion, steam reforming to syngas, and halogenation.
