Term 3 Test is schedule for Monday, Nov. 10, 2008. Review should be
premised on the following:
1. Quiz 4 serves as the main template for the test.
2. Redraw an organic structure into a Lewis diagram in order to determine
the molar mass of the organic compound.
3. Draw planetary models of any atom of elements atomic numbers 1 to 18.

Quiz 4 is rescheduled for Monday, Nov. 10, 2008. The following is a list
of items that will be on the quiz:
1. Limiting and excess reactant stoichiometric calculation.
2. Write a chemical equation from word form, then balance the chemical
equation and perform a stoichiometric calculation.
3. Pertaining to a molecular compound:
- Draw its Lewis diagram which shows the sharing of electrons and the
dipole moments (dipole arrows) of each bond
- Name of the compound
- Molecular shape
- IMF
- Miscibility or immiscibility with water, ethanol or oil
- Rate the strength of its IMF relative to other compounds.

Term 2 Test is schedule for Friday, Oct. 17, 2008. The following is a
list of items that may be on the test:
1. Quiz 3 will serve as a template for Term 2 Test. Therefore, a
reveiw of the items from Quiz 3 is a good idea. Also, the list
of items for Quiz 3, which is posted below, also serves as
a basis for Term 2 Test.
2. Questions regarding molecular/ covalent compounds:
- employ electronegativity value to determine the polarity of a bond
between two non-metal elements
3. List the level of organization the delinates the reductionist
perspective of the biosphere

Quiz 3 has been rescheduled for Wednesday, Oct. 8, 2008. The following is
a list of items that may be on the quiz:
1. Provide the name and/or chemical symbol for any element from Atomic #1
thru #36.
2. Classify an element as either a metal, metalloid, or non-metal.
3. Provide the chemical formula of an ionic compound when given its name
and vice versa, and calculate its molar mass.
4. Use dimensional analysis to solve mole conversion involving ionic
compounds. Conversion can be either:
- mole of compound to grams of the compound or vice versa
- mole of compound to number of formula units of that compound or vice
versa
- grams of a compound to number of formula units of the compound or vice
versa.
5. Determine the type of bond that could be formed between two different
elements based on their electronegativity differences.
6. Compare two different chemical reactions, each with one common
reactant. Hypothesize which reaction would be more vigorous and provide
explanation for your choice.

NOTE: The information shown below regarding Term 1 Test is a revision of
the information that was posted on Sept. 16, 2008.
Term 1 Test is schedule for Thursday, Sept 18, 2008. The following is a
list of items that may be on the test:
1. Quizzes 1 and 2 will serve as a template for Term 1 Test. Therefore, a
reveiw of the items from both quizzes is a good idea. Also, the lists
of items for Quiz 1 and Quiz 2, which is posted below, also serves as
a basis for Term 1 Test. HOWEVER, specific questions from the Chapter 1
homework will NOT be included in the Term 1 Test.
2. There WILL NOT be any questionS regarding ionic compounds that contain
polyatomic ions (as originally stated in the Sept. 16th posting).
