Explain how gas chromatography is used to separate samples of a gas mixture 23 explain how solutes can be separated by chromatography based on intermolecular interactions 24 design or interpret results of a separation experiment( filtration, paper chromatography, column chromatography, distillation) in terms of the relative strength of interactions among and between the components 25 explain the trends in properties and predict properties of samples consisting of particles with no permanent dipole on the basis of London dispersion forces 26 qualitatively analyze data regarding real gases to identify deviations from ideal behavior and relate these to molecular interactions 27 describe the relationships between the structural features of a polar molecules and the forces of attraction between the particles 28 explain the properties( phase, vapor pressure, viscosity, etc) of small and large molecular compounds in terms of the strengths and types of intermolecular forces 29 relate temperature to the motions of particles, either via particulate representations, such as drawings with arrows indicating velocities and/or via representations of average kinetic energy and distribution of kinetic energies of particles, such as plots of the Maxwell-Boltzman distribution 30 identify the noncovalent interactions within and between large molecules and/or connect the shape and function of the large molecule to the presence and magnitude of these interactions
