Hello. I am Dr. Zellmer. I am teaching Chem 1220 Autumn Semester.
<br>
I apologize if you are getting this and you are not signed up for
Chem 1220.<br>
I got the current roster with your e-mails from the registrar (SIS,
Buckeyelink).<br>
In a follow-up e-mail I'll discuss the textbook options. Hold off
on<br>
purchasing anything if you haven't already.<br>
<br>
If you are on a wait list I'm sending this info to you as well so
you know<br>
it if and when you get in the course. You can get to all the
material on<br>
my web pages but you won't have access to Carmen. If you are still
on<br>
the wait list when we start next week you can <b>not </b>go to lab
but come to<br>
lecture and the recitation you're trying to get into.<br>
<br>
Our Carmen pages will be activated tonight. The learning management<br>
system for Carmen is Canvas. There may be some changes which have<br>
to be made. You will access MasteringChemistry and the eText
through<br>
the MyLab and Mastering link in the menu for the course.<br>
<br>
The semester technically starts on Tuesday, 8/20/19. That would be<br>
recitation, for those who have recitation on Tuesday. We WILL have<br>
recitation that day. We start lecture on Tue.<br>
<br>
You do meet for lab the first week if you have Wed., Thur. or Fri.
lab.<br>
That will be CKN (check-in), where you get situated in lab, learn<br>
about safety, TAs discuss lab procedures, etc.<br>
<br>
The links to my homepage and the class link (which can be found at<br>
my homepage) are,<br>

<br>
<a
href="https://www.asc.ohio-state.edu/zellmer.1/chem1220/chem1220.htm"><u><b>Chemistry
1220 - F19</b></u></a><br>
<br>
There you will find the lecture and lab syllabi. These are also on<br>
Carmen. I'm working on an audio/visual edition of the syllabus for<br>
my web page. It is not quite ready. I'll let you know when it is.<br>
I highly suggest you look at this version. I've discussed things
about<br>
the course, including about lab, in a lot of detail. <br>
<br>
There's also a "little" note to let you know a few things about
1220. <br>
Read the WHOLE message at the link listed below and any to follow: <br>
<br>

<br>
This will make things easier for you when we start on Tue, 8/20/19.
<br>
If you notice a mistake or something that looks "strange" (reference
to<br>
quarters, incorrect dates, etc.) let me know. <br>
<br>
You can find further details at the link above.<br>
<br>
Then go to the "Notes" link. There you will find a copy of the
notes<br>
(overheads) I will be using in lecture. I highly suggest you print
them<br>
and bring them with you (print them with two pages to a single
physical<br>
page to save paper). Technically, we start with chapter 13 but I
will<br>
cover a few things you need from ch 11 first. Just print Ch 13 for<br>
now since I may be making some minor changes to some of the later<br>
chapters. You will also see what sections from 1210 you should
review.<br>
Do that now before we start rather than starting chapter 13. Pay<br>
particular attention to ch 11 (attractive forces, properties of
liquids,<br>
vapor pressure, heat of vaporization, boiling point - things needed
for<br>
exp 14 and ch 13) and ch 12 (which is the material you need to know<br>
concerning solids and taken from ch 11 of the 11th edition of the<br>
textbook). There's three links from the 12th ed. dealing with
solids.<br>
You probably won't need to know much about unit cells and related<br>
calculations. <br>
<br>
There's also a link to a table about the types of solids, their
attractive<br>
forces and their properties (which depend on their AF). It is very<br>
important to understand this material since we will be talking about<br>
solubility of solids, which depends on AF. The link is,<br>

<br>
I won't lie to you. This class will be tough. This class is going
to move<br>
pretty quickly and the material is generally more difficult than the
material<br>
you covered in Chem 1210. You saw most of the 1210 material in high<br>
school. Most of you will not have seen the material in 1220 in high
school,<br>
especially at the level at which we cover it. Plan on spending at
about 15<br>
hours a week outside of class just on lecture material and homework
and<br>
another 3-5 on lab work (preparation, reports, etc.).<br>
<br>
I've been teaching most of this material for about 28 years. I know
very<br>
well what things you need from this course for courses down the road
and<br>
exams you may some day take to get into graduate or professional
school.<br>
<br>
You do meet for lab the first week if you have Wed., Thur. or Fri.
labs.<br>
All labs meet the second week. You'll find the full schedule of
labs<br>
in the lab syllabus, which is on Carmen (and my class web page as
well).<br>
<br>
For W,R,F lab sections your first lab consists of CKIN (check-in) in<br>
which you will learn things about the lab room and lab procedures.<br>
During this lab period you will familiarize yourself with the lab
and<br>
review the use of various pieces of glassware, lab techniques, the<br>
notebook, etc.<br>
<br>
You can find guidelines of what should be in the notebook in the lab
manual,<br>
the lab syllabus, my web page and the link below. The link below is
very<br>
important and will take you to a lab page. You'll see several
things there dealing<br>
with lab.<br>
<br>
<a href="https://uglabs.cbc.osu.edu/1220">https://uglabs.cbc.osu.edu/1220</a><br>
<br>
I also have some things on my class web page (not Carmen) that will
help<br>
with lab. The first link is the Chem departments web site which can
be<br>
found at the above link. It has extensive instructions concerning
the notebook<br>
with an example. The second link is my suggestions for how to break
down<br>
the procedure into an easy outline to follow in lab (based on an old
exp, exp 14).<br>
Mine is just a shortened example and is similar to the first one.<br>
<br>
<a href="https://uglabs.cbc.osu.edu/gc-labnotebook/"><b>Chem Lab
Notebook Exercise - Guidelines for Lab Notebooks</b></a> <br>
<br>
<a
href="https://www.asc.ohio-state.edu/zellmer.1/chem1220/lab/notebook_proc_1220.pdf"><b>My
Suggestions for Writing a Notebook Procedure</b></a> <br>
<br>
You should write your procedure in your own words in an outline form
as shown<br>
in the examples above. Concise steps (only 1 or 2 things to do per
step).<br>
<br>
You should bring your goggles from 1210, if you still have them. If
not you<br>
can borrow a pair or will be given pair in lab (if you didn't take
chemistry<br>
here) so don't worry about that.<br>
<br>
We are concerned about lab attire. You must wear the proper lab
attire. Make<br>
sure you aren't wearing sandals, shoes which expose the top of the
foot or toes,<br>
shorts, short skirts, spandex, leggings, yoga pants or other
skin-tight pants,<br>
pants with holes or tank tops. If you are, you will be sent home to
change and<br>
not given additional time for completing the lab. You need to wear
long pants<br>
or dresses/skirts which cover the ankles. You shouldn't even wear
sweat pants<br>
or pajama bottoms, even if they cover the ankle. Chemicals can
either get<br>
through them to your skin fairly easily or perhaps even react with
the material<br>
(particularly leggings and hose). The best thing to wear are
jeans. Things don't go<br>
through them easily. You should wear a top which covers your
shoulders and chest.<br>
The best shoes are running/tennis shoes or hard shoes which cover
the entire foot (no<br>
open-top shoes). There's a more extensive list in the lab safety
statement on Carmen.<br>
Essentially your body from shoulders to the ankles and feet should
be covered. We are<br>
concerned about your protection.<br>
<br>
Okay, that's it for this e-mail. Many more will follow later and
throughout the<br>
semester. I will work very hard for you and I expect the same from
you.<br>
<br>
