Fri-Day 2
AP Chem - we began our Quantom Atom unit by showing the various characteristics (and their meaning) of electromagnetic waves: amplitude, wavelength, frequency, and speed.
We discussed how atomic theory evolved as better technology revealed more and more about the nature of the atom. We will continue with Rutherford, Bohr, et al on Tuesday.
Expect questions on the following:
1. Gas stoichiometry with emphasis on applying the gas laws to determine moles and masses of reactants and products. There will be a repeat of the question part involving the determination of all aqueous ion concentrations after a reaction has gone to completion.
GETTING THE CORRECT BALANCED EQUATION MAY REQUIRE THAT YOU BALANCE THE EQUATION VIA THE REDOX HALF-REACTION METHOD IN EITHER BASE OR ACID SO MAKE SURE THAT YOU REVIEW THAT METHOD. MOST OF YOU DID WELL WITH THAT ON THE SOLUTION STOICHIOMETRY TEST.
2. Descriptive chemistry/ equation writing of the four "gas-forming reactions" (see answers to equation writing assignment posted on Edline (posted this weekend)! Your grades for that assignment are also posted).
3. Explanation, in terms of (a) molecular collision frequency and (b) molecular collision force/kinetic energy,
of any permutation of the ideal gas law.
4. Graham's Law of Effusion in terms of relative rates OR times for different gases.
5. Average (rms) speed of a gaseous molecule of a substance at a given temperature.
6. Dalton's Law questions involving partial pressure, mole fraction, and total pressure. Among other things, this applies to reactions in which a gas is collected over water.
7. Van der Waal's gas equation and the explanation of the magnitude of the "a" and "b" correction factors of a given substance.
8. the postulates of kinetic-molecular theory relating to the how and why a real gas will behave ideally or will deviate from ideal behavior.
Bio - we showed with examples, the net results of mitosis and cytokinesis, with special emphasis of the fact that the daughter cells produced contain the SAME number and types of chromosomes that the original cell had; that is made possible by the DNA exact replication/doubling during the S phase of interphase, and the even separation/distribution of the chromosomes at anaphase.
We discussed the three purposes/uses of cell division - continued efficient metabolism, growth of a complex organism, and repair of damaged tissue.
In 7/8, we went on to discuss cancer/cancer cells.
