The
PLE for Monday, February 24th is ready. There are several QuickTime movies
in this PLE.PS6
issues/errors:In PS6.7a the concentration of Mg(NO3)2
should be 0.425 M and in part c) the concentration of propylene glycol should
be 0.120 molal. Do you know what the structure of propylene glycol is?
A student discovered that the molar mass calculated
for KHP in PS6.9 does not agree with the actual molar mass of potassium acid
phthlate. So there is an error in the data somewhere. So FYI, if you compare
the calculated molar mass to the actual molar mass they will not agree! I've
decided to leave the numbers alone, so simply report the value you calculate.
PS6.8b I use the name glucose, but I give the
formula for sucrose. So change glucose to sucrose so the name and the formula
match.
I have a SHOW
ME!/HELP ME! problem for PS6.PS6
due on Friday by 4:30 pm in the envelope outside my office.Lab
this week in in your Lab Manual titled Cation Qualitative AnalysisThe
class average on this exam was 60!!!!! The highest grade was a 96 by Todd
Mollet! CONGRATULATIONS Todd! Way to go. Lots of swag on Friday. I have some
new stuff from my trip to Washington! I'm working on the grades database and
the software for the personal page. So another 30 minutes and grades will
be up.A
few students are having some problems with the PLE. The message you receive
is " There is a major problem. The PLE database does not recognize you.
Your responses have been recorded into a SCRATCH database. Note the time you
did this PLE and Contact Dr. Gelder." Inorder to diagnose this problem
I need to better understand what you were doing at the time. So if you get
this message send me an e-mail. I'm saving the responses to a SCRATCH file
but there are NO names on the responses. How to avoid this problem?! Before
doing the a PLE be absolutely sure that you see your name on your Personal
web Page at the top of the left hand frame, and you see your name in the PLE
form itself. If either are missing DO NOT DO THE PLE until you have re-logged
in to your Personal Web page. The issue has to do with how much time you are
on your personal web page and nothing is happening. If you have been logged
on to your personal web page for a while, and done nothing it may have timed
out, so it no longer knows who you are. Be careful before doing the PLE! This semester I want to try using personal
web pages. To take advantage of this new feature you will have to give me
a Secret Identification number or name. Go to the SID#/Name link in the left
frame and complete the information requested. After you have given me your
SID information you will be able to access your own personal CHEM 1515 Web
page through the Personal Page. The personal page will have information specifically
associated with you: grades, PLE's, homework, exams, plus other way cool stuff.
So get your SID set up now!

Since this is the FIRST time I have tried to use the Personal Web Page concept there are going to be problems. You must e-mail me, or contact me when you have problems so I can solve them quickly. Hang in there, it is going to be FUN! this semester.
Here are this semester's laboratory sections.
