Day 9

G in 116 (no extension, no ppt, no video...) did catchup demos of endo and exo
showed energy curves and did activation energy....
HADN'T EVEN DONE HETEROGENEOUS MIXTURES!
did that and then did boxes of mixture vs. compound.
solution = homogeneous mixture Tyndall test.

D;finished up energy unit
E: as well and then did some review in the workbook...

unit errors: didn't draw energy arrows in phase change (s) --> (aq) pictures...would have been clearer....forgot to put up endo/exo worksheets....!
just stick to JD's notes...copy and scan and that's it!
didn't focus on alloys/solid solutions....

AP: did stoichiometry (power of the mole) gravimetric analysis to determine unknowns...hesitated and messed up units on the unknowns' molar mass...then corrected in class...should post a few more examples with correct units!
then started first mixture problem! show alternate way also...
