Chemistry question:
Given: CH4 + 2O2 ~ CO2 + 2H2O
C - H = 99 kcal O - O = 119 kcal
C = O = 192 kcal O - H = 111 kcal
Calculate the change in energy for the CH4 - O2 system.

dHrxn = (n*dH BE reactants) - (n*dH BE products)
BE = bond energy which you have listed.
To get you started C-H is 99 kcal and you have four of them so you must break 4 C-H bonds at 99 each so it costs almost 400 kcal to break those four bonds. Then you put together CO2 and you must break a O-O bond but form two O=C bonds in forming O=C=O. etc.
