1. The atomic weight of gold is 196.97. How many grams of gold are there in an Av ogadros number of gold atoms? Argon is an inert element but it becomes liquid below -185.8 °C. Upon further cooling, it becomes a solid FCC crystal below -189.4 °C *() The bonding forces in liquid state of Argon are covalent and van der Waals. T or F (ii) The bonding forces in the solid state are pure van der Waals bonds. T or F (iii) At precisely-189.4 °C, liquid Ar and solid Ar co-exist together. In this mixture, all possible types of bonds that exist are covalent and van der Waals. T or F Van der Waal forces disappear when an ionic crystal such as lithium chloride becomes a liquid at high temperature. T or F 2. 3. 4. 1 um 109 meters. 5. The four types of bonding in materials are_

    INTERMOLECULAR FORCES INTRODUCTION LEARNING OBJECTIVES To relate the effecet of intermolecular forces on relative melting points and vapour pressures of some organic substances THEORY Weak attractive forces that occur between individual molecules in substances are called intermolecular forces. These include London dispersion forces, dipole-dipole forces and hydrogen-bonding forces. Collectively, the three types of intermolecular forces are referred to as Van der Waals forces. These attractive forces are much weaker than the chemical bonds between atoms in a molecule. Note that...
