CHEM A105L - General
Chemistry I Lab
General Chemistry I Lab is a
laboratory course designed to teach the fundamentals of working
with laboratory equipment, data gathering, analysis, and
reporting.
All CHEM A105 labs are held in
CPSB 312. You must attend the first day of labs and you must
attend with your lab manual and goggles. Both are available
through the campus
bookstore. Labs start on August 24th, 2009.
For your convenience, we've
posted several files below that you may find useful at some point
during the semester. Please check back frequently to remind
yourself of what's available here. Some of our files are
posted in PowerPoint format. Others are posted in pdf format. If you don't already have it, the
Adobe Acrobat Reader can be
downloaded for free.
