Termochimica

ΔHf° (s): -93.4 kcal/mol 1 = -390.79 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° (s): -932.26 kcal = -3900.6144 kJ
