Overall Update

Today:

SLO Project

1) I studied the CCSF Chemistry SLO website in more detail to extract information pertaining to the four questions I have about the SLO process.
2) I sent two more email inquiries to a Glendale Community College chemistry professor and division chair and to a San Jose City College chemistry faculty and member of the SLO committee.

Lab Manual
1) I received a response from Mike about looking at the revised 3102 lab as he concedes that he has the same issues with the current one.
2) I checked on my copper oxide compound left overnight drying in the fume hood.  It seemed pretty dry but the mass I got for the compound indicated a CuO2 formula which does not make sense.  I suspect  that there is still water so I left it again overnight in the fume hood for weighing tomorrow.  It might be better if students use the oven for drying and dry to constant weight.

Physio-Micro Questions
1) I finally finished reading Chapter 18.
2) I have now about 36 questions from Silverthorn's text.
3) I added more notes about O2 and CO2 transport.

Articles:
I downloaded more articles for reading.

Others:
First day of installation for the GC-MS.  I chatted with and watched the guy installing it for a while.
I looked for LLNL posters in my email for archiving.

Lab Manual Update - 31



Chem 31 - Replacement salts for lab 3102
I finished writing a draft of a possible new Lab 3102.  I sent a copy of it to Mike for review with notes on my observations.

Lab Manual Update - 30A

Chem 30A - Another option for empirical formula lab:

I started a trial run of using the formation of a copper oxide compound to determine empirical formula.  This one does not require heating to dryness to recover the compound for weighing.  It does produce a lot of NO2 and requires some very low heating to accelerate formation of the copper oxide.






 





































The solid product is filtered. I am letting it sit overnight on filter paper and inside the fume hood for drying and weighing tomorrow.

Will update if overnight drying is sufficient.

Lab Manual Update

Completed trial run of replacement test compounds for lab 3102.  Yesterday, I did all the tests for the knowns.  Today, I did test for the unknowns.
