1. Compare the program model predicted direction of the dipole moment of NH3 with the predicted direction of the dipole moment in PCl3. Are they the same direction? Why or why not?

2.Compare the measured O-O bond lengths in O2, H2O2, and O3. The O-O bond in O2 is a true double bond, the O-O bond in H2O2 a true single bond. Using the concept of resonance, explain why the bond length in O3 is longer than the double bond but shorter than the single bond.
