Exam 2 Objectives



The Student will be able to:
1 Discuss polymers and monomers.
2 Discuss relative melting points (boiling points) and attractive forces of molecules and ionic compounds--know how to deduce the formula for simple ionic compounds such as sodium oxide...
3 Discuss relative melting points (boiling points) and structures of network covalent compounds.
4 Discuss, identify, and create phase diagrams.
5 Sketch SC, FCC, and BCC unit cells; discuss relative packing efficiencies; identify the equivalent number of atoms in the unit cells; and calculate the densities of SC, BCC, and FCC materials.
6 Discuss and calculate boiling point elevation.
7 Discuss and calculate freezing point depression.
8 Discuss and calculate osmotic pressure.
9 Use the "like dissolves like" rule to predict whether a particular solute will dissolve in a particular solvent.
10 Define and discuss the terms lattice energy and solvation energy in relation to formation of solutions.
11 Calculate molality given necessary information about solute and solvent.
12 Discuss intermolecular forces.
13 Discuss soaps.
14 Discuss why molality is used in colligative property calculations rather than molarity.
15 Discuss and calculate vapor pressures and freezing points based on interpolation of data.
16 Discuss half-lives.
17 Discuss exponential decay.
18 Discuss and determine the times and amounts of decay.
19 Discuss means of increasing reaction rates.
20 Discuss reaction orders.
21 Determine the rate law of a reaction given experimental data.
