7. Balance the chemical equations of Problem 6 by the half-reaction method.

8. Balance each of the following equations by any convenient method:

(a) C7H16 + O2 CO2 + H2O (complete combustion)
(b) C7H16 + O2 CO + H2O (incomplete combustion)
(c) C7H16 + O2 C7H12 + H2O

9.The mass of the atom is 15.9949 amu. Calculate the mass loss per nucleon, and the binding energy per nucleon. How do these values compare with those for iron-56?

10. Write a balanced nuclear equation for the fusion of three helium-4 nuclei to form a carbon-12 nucleus. What quantities must be conserved in the balancing process?
