4. a) The enthalpy change of combustion of hexane was measured using a calorimeter containing 200 cm3 of water; 0.5g of hexane (C6H14) was burnt. The temperature of the water increased by 30 K.
Calculate the enthalpy change of combustion of hexane.
(c=4.18 Jg -1K-1).
Give your answer in kJ mol-1.

I got -24794kjmol-1 as combustion for hexane. Do you need to do anything else for the question?

bond values (from previous question):

c-c 347
c-h 413

c=o 805
o-h 464

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
