So I have this question on a test not sure how to do this. Thanks in advance for any help you may provide me.
Homework Answers
First of all the values provided in the question is incorrect as the Octane should be (C8H18) rather than (C2H4O)and the value of Delta Hf should be (-250.1 KJ/mol).
Please find the solution with correct Values:

18. Octane (CHıx) undergoes combustion according to the following thermochemical equation. 2C3H13() + 2502(g) → 16CO2(g) + 18H2011 AHnx = -1.0940 * 10ºkJ/mol What is the standard enthalpy of formation of liquid octane? AH* (CO2(g)) = -393.5 kJ/mol and AH® (H20(0) = -285.8 kJ/mol A.-250 kJ/mol B. -10,940. kl/mol C.-2188 kJ/mol D. -495 kJ/mol E. 495 kJ/mol
