Yesterday, 9:02 PM  | Molar Heat of Combustion You can hide this advertisement by registering. Why is it useful to know the molar heat of combustion of hydrocarbons? I understand that I can help with determining the efficiency of them as fuels but apart from that... |

Yesterday, 12:15 PM Blog Entries: 1 | Re: Molar Heat of Combustion Quote:
- we assume complete combustion but you can see soot forming at the base of the beaker - our heating methods were not 100% efficient because some heat could have been lost to the air. Other things molar heat of combustion is useful for is for comparing ethanol and octane as a fuel: ethanol is 1364Kj/mol and octane is 5467kJ/mol.
