Answer: Three common hydrocarbons that contain four

Chapter , Problem 108AE

(choose chapter or problem)

Three common hydrocarbons that contain four carbons are listed here, along with their standard enthalpies of formation:

(a) For each of these substances, calculate the molar enthalpy of combustion to \(\mathrm{CO}_{2}(g)\) and \(\mathrm{H}_{2} \mathrm{O}(l)\)

(b) Calculate the fuel value, in \(\mathrm{kJ} / \mathrm{g}\), for each of these compounds.

(c) For each hydrocarbon, determine the percentage of hydrogen by mass.

(d) By comparing your answers for parts (b) and (c), propose a relationship between hydrogen content and fuel value in hydrocarbons.
