Using the information in the table to the right, calculate the enthalpy of combustion of each of the following substances:
acetylene:
ethanol:
The combustion of 0.25 mol of an unknown organic compound results in the release of 320 kJ of energy. Which of the compounds in the table could be the unknown compound?
ANSWERS:
1.
acetylene: -1,256 kJ/mol
ethanol: -1,277 kJ/mol
2.
ethanol
I already know the answers (they're right there ^) i just need to know HOW you find the enthalpy combustion of acetylene and ethanol.
