Why is '-ethane' in 'methane'? - Chemistry Stack Exchange
2020年11月18日 · methane vs ethane. That these both end in -ane is not a coincidence - all alkanes end in -ane. As stated in AChem's answer, this nomenclature was introduced by A. W. Hofmann in 1865. Acknowledgements. Maurice's answer inspired me to find the first work by Dumas that led to the methyl terminology.
Why isn't ethane used for cooking? - Chemistry Stack Exchange
2020年4月30日 · Methane and ethane are very hard to be liqufied with respect to propane and butane. To make methane liquid requires highee pressures and this means more cost and danger. But especially, n- butane may be easily liqufied and liquid phase covers less volume.
Combustion of methane and ethane - Chemistry Stack Exchange
2020年10月17日 · I'm having trouble with the following problem: A gas fuel of Methane ($\\ce{CH4}$) and Ethane ($\\ce{C2H6}$) is burned with atmospheric air, and the volumetric analysis of the products of combustion
Why is the melting point of propane lower than that of both …
2016年2月16日 · The phase transition towards solid state involves crystalization, i.e. organization of the molecules into the long-range repetitive patterns. The formation of crystal lattice is reasonably simple for balls (methane) and rigid sticks (ethane), but becomes problematic for flexible triangle (propane), which needs to be properly aligned.
combustion - What is the significance of heating value?
2020年7月3日 · It is $\pu{890 kJ/mol}$ for methane, but $\pu{2200 kJ/mol}$ for propane, which is roughly $\pu{730 kJ/mol}$ for carbon. For methane, both numbers are the same, as a propane molecule contains 3 carbon atoms, while a methane molecule just 1. So methane has a an advantage as energy source, as it has higher energy production per the same $\ce{CO2 ...
organic-chemistry combustion hydrocarbons - Chemistry Stack …
2016年2月25日 · In well controlled environment where the oxygen-fuel ration is set carefully most hydrocarbons burn cleanly with little soot. Gas-based cookers (using mostly saturated methane, ethane, propane or butane) are very clean because they control the gas mix very precisely (use the wrong burner and they may well be sooty!).
physical chemistry - Ethane and ethene: which is easier to burn?
2014年12月21日 · Ethane will release more heat per mole but ethene should produce a higher temperature. The extra heat released by ethane goes into heating up more water which has a high heat capacity. As for which has lower activation energy, ethyne is dangerous to store because it can explode so I am assuming ethene is faster to react because of some trend.
Why does ethane release more energy than ethyne when burned?
2018年7月18日 · The red arrows and numbers are the heats of combustion of the three hydrocarbons. Although acetylene and ethylene have a headstart in combustion because the are less stable than ethane, all three compounds produce two CO 2 's but ethane generates more water than acetylene and ethylene. Ergo, ethane generates the greatest amount of heat.
Conversion of methane to propane - Chemistry Stack Exchange
2019年4月13日 · It was shown by Alexander Goncharov and coworkers by placing methane in a diamond anvil cell, applying a pressure of more than 2 GPa and heating everything to a temperature around 1000-1500 K with a laser. Is it economical? Hardly, but very interesting anyway! Kolesnikov, A.; Kutcherov, V. G.; Goncharov, A. F. Nature Geosci 2009, 2 (8), 566–570.
Converting methanol into methane - Chemistry Stack Exchange
2015年4月9日 · But it's worth noting that the partial oxidation of methane, that is, converting methane to methanol, has been a "holy grail" of chemical engineering for many decades. That is, an oxidative, (comparatively) low-temperature, low-pressure process to achieve $\ce{CH4 + 1/2 O2 -> CH3OH}$ efficiently & economically, has been a goal of industrial ...
