Chemblog!

AP, Honors, and Regents classes:
I haven't yet been able to post hw and powerpoint files for any classes tonight so just review notes from today for hw. Later tonight, I will post all files that can be done for hw tomorrow. G'night.
update: very long day...
hw files and powerpoints are up for tomorrow...Honors and Regents classes should find the Atomic Concepts powerpoints helpful; the text does a pretty good job with its illustrations also. The Thomson audio and video files are posted too.

AP- had our Gas Law and Gas/Solution Stoichiometry exam today. Another long one but we have to cover the important question types...next test will have the missing Graham's Law questions and some more Gas Law explanations...

Honors: we started the important description and explanation of the major models of the atom: Dalton to Thomson and then later we will do Rutherford to Bohr to the Modern Quantum Mechanical Model of the atom.

Regents: we did some practical calculations involving the mole and the atomic mass scale.
