It can be measured experimentally with considerable accuracy and generally is reported as … oz in 1 quart water
Key to "What is the heat of combustion of ethane,..." - Plainmath
WebEthane is an alkane with the chemical formula C 2 H 6. As a hydrocarbon, it can undergo hydrocarbon combustion which gives off heat. Ethane is one of the hydrocarbon components of natural gas, which is a type of fossil … WebDec 21, 2014 · 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.
