Answer to Question #251755 in General Chemistry for Mikay

Question

Determine the value of the heat of combustion (kJ/g) of ethanol by using the bond
energies.
Note: All single bonds in ethanol structural formula.

Answer 1

Add together the bond energies for all the bonds in the reactants - this is the 'energy in'

Add together the bond energies for all the bonds in the products - this is the 'energy out'

Energy change = Energy in - energy out.
