exam 3 information

1	Describe the main ideas of the Thin Layer Chromatography experiment, including what is meant by TLC as a technique and how to carry out a separation.
2	Describe the main ideas of the Enthalpy experiment, including the steps required to obtain an enthalpy of solution and why you had to perform two separate enthalpy determinations.
3	Describe the main ideas of the Dyeing to Bond experiment, including the different ways in which the dyes you studied actually adhere to fabrics and the lessons from the multi-fabric strip as far as the results of using dyes on different fabrics.
4	Describe what is meant by geometric isomerism and predict whether a given alkene will have cis and trans isomers.
5	Describe the ideas behind molecular orbital theory, use MO theory to predict the bond order of simple diatomics from the first two periods of the periodic table, and compare those results with the predictions of VSEPR and VB theory.
6	Describe the molecular orbitals used for the case of benzene and account for benzene's lack of "alkene behavior."
7	Identify and name aromatic compounds listed during lecture (toluene, phenol, the xylenes) using traditional as well as systematic naming conventions.
8	Describe and distinguish intra- and intermolecular forces and the roles they play in determining the three phases of matter.
9	Describe and distinguish between the three phases of matter and the role of average thermal energy in each.
10	Describe phase changes and calculate energies involved in phase changes.
11	Describe the main ideas behind a refrigeration unit or heat pump.
12	Give examples of dynamic equilibria involved in establishing vapor pressure and other equilibria between phases, and describe how vapor pressure is related to temperature.
13	Define what is meant by terms such as vapor pressure, boiling point, normal boiling point, freezing point, normal freezing point, triple point, critical point, fusion, sublimation, deposition, surface tension, network covalent solids, crystals
14	Use a phase diagram to predict behavior of a material as temperature and pressure are changed, to predict conditions under which fixed temperatures should be established, and to predict heating and cooling curve parameters.
15	Explain the boiling process and explain how applied pressure is related to temperature for a boiling system.
16	Describe the types of intermolecular forces we have discussed and predict relative boiling/melting points of compounds based upon molecular structures or ionic structures.
17	Describe what a hydrogen bond is, what is required for a hydrogen bond to occur, and what role hydrogen bonds have in determining molecular properties.
18	Describe the unusual properties of water and account for them.
19	Describe the three allotropes of carbon and explain why they have the properties they do.
20	Describe what are meant by simple, body-centered, and face-centered cubic crystals and calculate densities given crystalline parameters.
21	Describe what is meant by a solution in all senses of the word.
22	Use each of the concentration units: Molarity, molality, % by weight, % by volume, parts per million, parts per billion, mole fraction, and mole percent.
23	Describe the role of intermolecular forces in the solution process.
24	~~Apply Raoult's Law and Henry's Law to solutions, and distinguish between these laws in application.~~
25	~~Work problems involving freezing point depression and boiling point elevation.~~
