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.
Learn about the sources and uses of the greenhouse gas methane with this guide for KS3 chemistry students aged 11-14 from BBC Bitesize.
Methane (CH 4) is a greenhouse gas. It is the second-most abundant greenhouse gas after carbon dioxide (CO 2). Although methane is emitted in smaller quantities than ca rbon dioxide, its global warming potential is around 25 times that of CO 2. This means that it is more effective in trapping heat. Fortunately, methane has a short lifespan – ...
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.
Methane. The simplest hydrocarbon, methane is a gas with a chemical formula of C H 4. A principal component of natural gas, methane is a significant fuel. Burning one molecule of methane in the presence of oxygen releases one molecule of CO 2 (carbon dioxide) and four molecules of H 2 O (water): CH 4 + 2O 2 → CO 2 + 2H 2 O.
23 Δεκ 2023 · Methane is an organic compound with the chemical formula C H 4. It is an alkane with one carbon atom. It is often found as the main part of natural gas. Methane is a greenhouse gas [4] [5] 23 times more effective than carbon dioxide. It is also less stable and slowly oxidates by oxygen to carbon dioxide and water. Contents. Uses.
Methane, in which four hydrogen atoms are bound to a single carbon atom, is an example of a basic chemical compound. The structures of chemical compounds are influenced by complex factors, such as bond angles and bond length.
