Web1 day ago · The Lewis structure of the methane (CH4) molecule is drawn with four single shared covalent bonds between the carbon and hydrogen atoms each. Moreover, as there exist sigma bonds only and one 2s and three 2p orbitals of the carbon produce four new hybrid orbitals, the hybridization of CH4 is sp3. It is interesting to realize that irrespective ... WebOct 12, 2024 · 過去十年由於人類對能源和肉食的需求不斷提高，導致溫室氣體甲烷 (methane, CH4) 排放量增加了 9％ 。溫室氣體中吸收熱能高的甲烷主要來自石油和 ...
