Methane is a hydrocarbon that is a gas at room temperature (20°C). Its molecular formula is CH4, so it has one carbon atom and four hydrogen atoms in a molecule. It is often found as the main part of natural gas. Methane is a greenhouse gas 22 times more effective than carbon dioxide. It is also less stable and slowly oxidates by oxygen to carbon dioxide and water.
Uses[change | change source]
Methane is used in gas taps in places such as chemistry classrooms, laboratories, etc. as it burns very easily because of its simple molecular structure.
Molecular structure[change | change source]
Production[change | change source]
Methane can be produced by many chemical methods, but usually is found in natural gas and is obtained by fractional distillation, after it is become liquid. Methane's molecular structure is 1 carbon atom bound together with 4 hydrogen atoms.
