how much heat is released in(kcal)when burning one molecule of octane completely to carbon dioxide and water
Answers
Answer:
(Note: Your first step is to write down a balanced chemical equation: octane plus X oxygens goes to 8 carbon dioxides and 9 waters.) Note that there is a difference between burning one molecule and one mole! (There are 6.02 . 1023 molecules in one mole, and I am asking you to find it for one molecule.) The useful numbers below are per mole. In the video lectures, I did this same problem for burning methanol, except I did it for burning a complete mole. The heat of formation for: C: His: -59.2 kcal/mole H20:-57.8 • COy:-94,1 02:0.0 (by definition of the scale used) Upload a document that shows all of your work, including the balanced chemical equation. Make sure to also give your final answer for the energy released in burning one molecule.
