Dr. Sheets's Chem 110 Lecture Notes

 

 

Chemistry impacts every area of our lives. My goals for this course are for you to understand how what happens at the molecular level controls our macroscopic world, and how fun chemistry is. Chem 110 is a partnership between you (the student) and me (the professor). It will take a lot of work on your part—to keep up with the readings and homework. Don't go through Chem 110 alone: go to lecture, form a study group (& make some friends along the way), ask your TA questions, use the resources available on the Chem 110 website, go to the Chemistry Resource Room (211 Whitmore), go to SI (Supplemental Instruction), ask a question in class, come to my office hours... Please don't get behind in the material—we go through the material quickly at times, and we build on what comes before. I strongly recommend reading the text before lecture so that you can ask questions about material that may be unclear for you, and reviewing your notes and the text after lecture to clarify & reinforce the material. And finally, please don't start studying a couple of days a couple days before an exam(!?!).

Lecture notes for Dr. Sheets's sections of Chem 110 (sections 27-39) will be posted here for viewing or downloading as each set of lecture notes becomes available. To view a set of notes from a campus computer, simply double click on any one of the underlined lectures. From other computers, see the notes provided below. NOTE: these are not complete notes—they outline topics that will be discussed in varying detail during class. You are responsible for all of the assigned material, whether it is covered in lecture or not. Sections are intentionally left blank, and these notes serve only as an outline for the lecture: some sections may be skipped—you should fill these out from your own reading before & after lecture—and other sections may be emphasized during lecture. You should bring the notes to class and fill in missing and additional information during lecture and during your reading of the text before and after class.

These lecture notes are PDF files, which can be viewed in one of three ways:

1. Save the lecture note file, then you can view or print the notes at your leisure using Acrobat Reader*.

2. Configure your web browser to load Acrobat Reader* on start-up so that the notes are automatically loaded when you select the lecture notes for each day.

3. Paste the Adobe Acrobat plugin, which comes with Acrobat Reader*, in the plugins folder of your web browser. This will automatically load the Reader into your browser to view the notes.

You may find it useful to change the layout (under the print menu) to 2-4 pages per sheet of paper to conserve paper when printing.

*The web browsers on the campus computer labs are already configured to automatically load Acrobat Reader. If you are accessing this page from your home system, you may need to get a copy of Acrobat Reader to view PDF files. Acrobat Reader is freeware which can be downloaded from www.adobe.com . There is also online documentation there that may be helpful.
