QUESTION 6 Two crystalline solids, P and Q have melting points of 710oC and 723oC respectively. At 700oC, substance P conducts electricity but Q does not. At 750oC, both P and Q conduct electricity. 6.1 What can be deduced from the melting points about the relative magnitude of the forces between the particles in P and Q? (2) 6.2 Explain the difference observed in electrical conductivity between P and Q. (4) 6.3 You are told that one of the solids is Barium and the other is potassium iodide. Which is P and which is Q? (2) 6.4 What is the difference between covalent and ionic bonding? (2) 6.5 Name 5 different types of intermolecular forces (5)
