Questions 1. Give two qualitative observations for each sample upon closer examination of the respective photos. 2. Sample Four was the only sample that contained an odour. What does this suggest about the ease with which the particles can leave the solid with respect to the strength of the intermolecular forces of attraction between the particles? ( 3. Which sample has mobine electrons for which to conduct electricity? 4. Sample Four was the only one that was soluble in a nonpolar solvent. What does this suggest about the polarity of the molecule in Sample Four? 5. Sample One was soluble in water and in its molten state conducted electricity, but in its solid state it did not conduct electricity. Electrons only flow in solids to produce current electricity. What types of particles does the experimental evidence point to the makeup of this sample? (T 6. What evidence is there to support the formation of ionic or molecular liquids of nonpolar crystals? 7. What could you deduce about the strength of the forces of attraction between the particles, in Sample 3, compared to the other samples? (1 mark) 8. Give 3 more physical tests to help you in your analysis of these samples and their subsequent identification.
