Welcome to Chem 1250 - Autumn Semester 2018

[Robert Zellmer]

Hello.  I am Dr. Zellmer.  I am teaching Chem 1250 Autumn Semester.
I apologize if you are getting this and you are not signed up for
Chem 1250.  I got the current roster with your e-mails from the
registrar (SIS, Buckeyelink).

Our Carmen pages are not yet activated.  They are working to get a
few things fixed, particularly with the lab material.  I will let you know
when they're ready (sometime today or tomorrow I hope).

If you are on a wait list I'm sending this info to you as well so you know
it if and when you get in the course.  You can get to all the material on
my web pages but you won't have access to Carmen.  If you are still on
the wait list when we start next week you can *not* go to lab but I 
encourage
you to come to lecture.

Our computer support is making some changes over the next few days
to our web server.  If you come across any broken links please let me know.
The actual addresses to my web pages will be changing but the old ones
should get redirected to the new ones once those are up.

The links to my homepage and the class link (which can be found at my
homepage) are,

*http://chemistry.osu.edu/~rzellmer/ 
<http://chemistry.osu.edu/%7Erzellmer/>*

_*Chemistry 1250 - F18*_ 
<http://chemistry.osu.edu/%7Erzellmer/chem1250/chem1250.htm>

There you will find the lecture syllabus.  I'm working on an audio/visual
edition of the syllabus and will let you know when it's done.

There's also a "little" note to let you know a few things about 1250.
Read the WHOLE message at the link listed below and any to follow:

http://www.chemistry.osu.edu/~rzellmer/chem1250/chem1250_intro.txt

This will make things easier for you when we start on Tue., 8/21/18.
If you notice a mistake or something that looks "strange" (reference to
quarters, wrong page numbers, etc.) let me know.

You can find further details at the link above.

Then go to the "Notes" link.   There you will find a copy of the notes
(overheads) I will be using in lecture.   I highly suggest you print them
and bring them with you (print them with two pages to a single physical
page to save paper).   If you took chemistry in high school chapters 1-4
should be a review of what you learned there.   I will make that assumption
so will be moving through it pretty quickly and skipping some things
in class.   If you didn't take chemistry in high school this is not the 
class
you should be taking.   You might want to check to see if you can take 1210
instead of 1250 or you may have to take 1110 first.

This class is going to move at almost the speed of light.   We've been
asked to cover almost everything we used to cover in 2 quarters (20 weeks)
in one semester (14 weeks).   I will be leaving some things out entirely.
Other things (the easier concepts) I may cover only briefly or not at all in
class but expect you to be able to pick it up by reading my notes and
the textbook (yes you will need to use the textbook).   I will let you know
as we go along.   This is one important reason to come to class. The notes
I will use in lecture are up on my class web page (not Carmen). These are
a copy of the overheads I will use.   You may want to print them and 
bring them
to class as it will make it easier to keep up.   As we go along I may 
find I need to
leave things out I planned to cover and are in the syllabus and notes.   
I'll let you
know when we get there.

I won't lie to you.  This class will be tough.   The material won't always
be easy, even if you saw it in high school, and there will be other things
most of you never covered in high school.   Then add in how fast we
need to move and it makes it tougher.   Plan on spending around 18
hours a week outside of class just on lecture material and homework and
another 3 or so on lab work (preparation, reports, etc.) for a total of 
~ 21 hrs.
There may be times due to the nature of the book material or lab material
it might take less or more time than 21 hours but you should plan on this.

Everyone *will be doing exp 1 *during the first lab session starting 
*this week*.
You should read it and write the procedure in your lab notebook.  If you 
don't
have the manual you can find the exp 1 manual pages on Carmen (see
the "Modules" link for exp 1 (SCM)).  If you don't have a notebook yet you
can get carbons from 231/331 Celeste Lab today or tomorrow before lab.

You can find guidelines of what should be in the notebook in the lab manual,
the lab syllabus, my web page and the link below.  The link below is very
important and will take you to a lab page.  You'll see several things there
dealing with lab.

https://uglabs.cbc.osu.edu/1250/

I have a summary of what should be in the notebook in the syllabus on
page 11 and an example of how to write the procedure in your own words
in an outline form on the class web page (based on exps 6 and 14) and 
syllabus
(page 13).

I also have some things on my class web page (not Carmen) that will help
with lab.  The first link is the Chem departments web site, which can 
also be
found at the above link.  It has extensive instructions concerning the 
notebook
with an example.  The second link is my suggestions for how to break down
the procedure into an easy outline to follow in lab (based on an old 
exp, exp 14).
Mine is just a shortened example and is similar to the first one.

*Chem Lab Notebook Exercise - Guidelines for Lab Notebooks* 
<https://uglabs.cbc.osu.edu/gc-labnotebook/>

*My Suggestions for Writing a Notebook Procedure* 
<http://chemistry.osu.edu/%7Erzellmer/chem1250/lab/notebook_proc.pdf>

You should write your procedure in your own words in an outline form as 
shown
in the examples above.  Concise steps (only 1 or 2 things to do per 
step).  All
three of the above links can be found by clicking on the "Laboratory" 
link on
my class web page (not Carmen).

You will be given goggles in lab so don't worry about that.   While it's 
not likely
with the current weather conditions, make sure you aren't wearing 
sandals, shoes
which expose the top of the foot or toes, shorts or short skirts. If you 
are you will be
sent home to change and not given additional time for completing the 
lab.  You need
to wear long pants or dresses/skirts which cover the ankles.  You 
shouldn't wear
leggings yoga pants, sweat pants or pajama bottoms, even if they cover 
the ankle.
Chemicals can either get through them to your skin fairly easily or 
perhaps even react
with the material (particularly leggings and hose).  The best thing to 
wear are jeans.
You should wear a top which covers your shoulders and chest.  The best 
shoes are
running/tennis shoes or hard shoes which cover the entire foot (no 
open-top shoes).
There's a more extensive list in the lab safety statement on Carmen 
(essentially your
body from shoulders to the ankles and feet must be covered).  We are 
concerned about
your protection.

Okay, that's it for this e-mail.  Many more will follow later and 
throughout the
semester.  I will work very hard for you and I expect the same from you.

Dr. Zellmer
