Answer all parts. (a) Sketch several H20 molecules interacting in the solid phase. Briefly explain why the [6 marks] addition of NaCI lowers the melting point of H20 (b) CO2 is a molecule that is not expected to have a dipole moment. Why? Your solution [2 marks] (c) When vibrationally excited, CO2 shows a slight dipole that increases with vibrational [5 marks] should make use of simple, well-labelled diagrams. excitation. Why? Your solution should make use of simple, well-labelled diagrams...
