Thermochemistry

ΔHf° (g): 9.85 kcal/mol 1 = 41.21 kJ/mol
S° (g): 125.36 cal/(mol•K) 2 = 524.51 J/(mol•K)
ΔGf° (g): 60.28 kcal/mol 3 = 252.21 kJ/mol
The heat of combustion is the amount of heat released when one mole of a substance undergoes combustion according to the general reaction equation:
CxHyOz + 0.25(4x+y-2z) O2 (g) → x CO2 (g) + 0.5y H2O (ℓ)

ΔHcomb° (g): -1565.185 kcal = -6548.7824 kJ
