Welcome to Chem 1220 - Autumn Semester 2019

[robert zellmer]

Hello.  I am Dr. Zellmer.  I am teaching Chem 1220 Autumn Semester.
I apologize if you are getting this and you are not signed up for Chem 1220.
I got the current roster with your e-mails from the registrar (SIS, 
Buckeyelink).
In a follow-up e-mail I'll discuss the textbook options.  Hold off on
purchasing anything if you haven't already.

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 come to
lecture and the recitation you're trying to get into.

Our Carmen pages will be activated tonight. The learning management
system for Carmen is Canvas.  There may be some changes which have
to be made.  You will access MasteringChemistry and the eText through
the MyLab and Mastering link in the menu for the course.

The semester technically starts on Tuesday, 8/20/19.  That would be
recitation, for those who have recitation on Tuesday.  We WILL have
recitation that day.  We start lecture on Tue.

You do meet for lab the first week if you have Wed., Thur. or Fri. lab.
That will be CKN (check-in), where you get situated in lab, learn
about safety, TAs discuss lab procedures, etc.

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

*https://www.asc.ohio-state.edu/zellmer.1/*

_*Chemistry 1220 - F19*_ 
<https://www.asc.ohio-state.edu/zellmer.1/chem1220/chem1220.htm>

There you will find the lecture and lab syllabi.  These are also on
Carmen.  I'm working on an audio/visual edition of the syllabus for
my web page.   It is not quite ready.  I'll let you know when it is.
I highly suggest you look at this version. I've discussed things about
the course, including about lab, in a lot of detail.

There's also a "little" note to let you know a few things about 1220.
Read the WHOLE message at the link listed below and any to follow:

http://www.chemistry.osu.edu/~rzellmer/chem1220/chem1220_intro.txt

This will make things easier for you when we start on Tue, 8/20/19.
If you notice a mistake or something that looks "strange" (reference to
quarters, incorrect dates, 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).  Technically, we start with chapter 13 but I will
cover a few things you need from ch 11 first.  Just print Ch 13 for
now since I may be making some minor changes to some of the later
chapters.  You will also see what sections from 1210 you should review.
Do that now before we start rather than starting chapter 13.  Pay
particular attention to ch 11 (attractive forces, properties of liquids,
vapor pressure, heat of vaporization, boiling point - things needed for
exp 14 and ch 13) and ch 12 (which is the material you need to know
concerning solids and taken from ch 11 of the 11th edition of the
textbook).  There's three links from the 12th ed. dealing with solids.
You probably won't need to know much about unit cells and related
calculations.

There's also a link to a table about the types of solids, their attractive
forces and their properties (which depend on their AF).  It is very
important to understand this material since we will be talking about
solubility of solids, which depends on AF.  The link is,

*Types of Solids and Their Properties* 
<https://www.asc.ohio-state.edu/zellmer.1/chem1220/notes/Table_13-10_solids_no_lines.pdf>

I won't lie to you.   This class will be tough.  This class is going to move
pretty quickly and the material is generally more difficult than the 
material
you covered in Chem 1210.  You saw most of the 1210 material in high
school.  Most of you will not have seen the material in 1220 in high school,
especially at the level at which we cover it.  Plan on spending at about 15
hours a week outside of class just on lecture material and homework and
another 3-5 on lab work (preparation, reports, etc.).

I've been teaching most of this material for about 28 years.  I know very
well what things you need from this course for courses down the road and
exams you may some day take to get into graduate or professional school.

You do meet for lab the first week if you have Wed., Thur. or Fri. labs.
All labs meet the second week.  You'll find the full schedule of labs
in the lab syllabus, which is on Carmen (and my class web page as well).

For W,R,F lab sections your first lab consists of CKIN (check-in) in
which you will learn things about the lab room and lab procedures.
During this lab period you will familiarize yourself with the lab and
review the use of various pieces of glassware, lab techniques, the
notebook, etc.

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.

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 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* 
<https://www.asc.ohio-state.edu/zellmer.1/chem1220/lab/notebook_proc_1220.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).

You should bring your goggles from 1210, if you still have them.  If not you
can borrow a pair or will be given pair in lab (if you didn't take chemistry
here) so don't worry about that.

We are concerned about lab attire.  You must wear the proper lab 
attire.  Make
sure you aren't wearing sandals, shoes which expose the top of the foot 
or toes,
shorts, short skirts, spandex, leggings, yoga pants or other skin-tight 
pants,
pants with holes or tank tops.  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 even wear 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.  
Things don't go
through them easily.  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 should 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
