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, a chemical compound with the chemical symbol CH4, comprises one carbon atom and four hydrogen atoms. It is classified as an alkane and a significant natural gas component. Its abundance makes it a desirable fuel, but its gaseous form at average temperatures makes transportation difficult.
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 23 times more effective than carbon dioxide. It is also less stable and slowly oxidates by oxygen to carbon dioxide and water.
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.
4 Οκτ 2024 · methane, colourless, odourless gas that occurs abundantly in nature and as a product of certain human activities. Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases. Its chemical formula is CH 4.
