half day today due to the snow and the day before was a wash due to the ashes...just got through charles's law with two of the classes and am up to ideal gas law with B period.
gave part one of a two part , 6 q, 140 point test today and it looks like the VM VM question killed some of them..their fault for not doing the worksheets....no brainer...

more demos more demos more demos and straight through...no more backtracking...that is it...the end....maybe for ten minutes on the day before a test......
no AP class at all today...acid base results are great so far....stress that Ka always ha H3O+ as a product and Kb always produces OH-
