The Complete Combustion of Carbon Compounds Produces Carbon Dioxide $\to$ CO₂(g)
(II)C(s)+ H₂O(g)

The complete combustion of carbon compounds produces carbon dioxide.The reaction of coal with water at high temperatures produces synthesis gas,which is a mixture of carbon monoxide and hydrogen.Use the bond energies in the table below to estimate how much more energy is released by reaction I than by reaction II.
(I) C(s) + O₂(g) $\to$ CO₂(g)
(II) C(s) + H₂O(g) $\to$ CO₂(g) + H₂(g)
