3. explain Boyle’s Law
4. explain Charles Law
6. apply the ideal gas equation to a variety of stoichiometric problems
7. apply the combined ideal gas equation to a variety of stoichiometric problems
8. apply the ideal gas equation to molar mass and density calculations
9. explain Dalton’s Law
10. apply Dalton’s Law to partial pressure and mole fraction problems
11. explain the process for collecting a gas over water and calculating its quantity
12. explain the assumptions for an “ideal” gas
13. apply kinetic molecular theory to explain physical observations
14. apply Graham’s Law of effusion to molecular mass calculations
15. explain deviations from ideal gas behavior
16. explain bond polarity
17. compare and contrast covalent network, ionic, covalent, dipole/dipole, hydrogen
bonding and London dispersion forces
18 use kmt and concepts of intermolecular forces to make predictions of the
macroscopic properties of gases in ideal and non-ideal situations
19 refine multiple representations of a sample of matter in the gas phase to accurately
reflect the effect of changes in the macroscopic properties of the sample
20 describe a metallic bond
21 describe a phase diagram
22 describe gas chromatography and its relationship to intermolecular attractions.
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
