Thermochimie

ΔHf° (s): -531.9 kcal/mol 2 = -2,225.47 kJ/mol
ΔHf° (s): -532.05 kcal/mol = -2226.1 kJ/mol 3
S° (s): 86.1 cal/(mol•K) 4 = 360.24 J/(mol•K)
ΔGf° (s): -369.18 kcal/mol 6 = -1,544.65 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): -1348.165 kcal = -5640.7804 kJ
ΔHcomb° (s): -1348.01433078394 kcal = -5640.15 kJ
