Chemistry Help Pages with Solutions
This is the entry point to
a set of pages aimed at aiding you in your studies of chemistry. The pages generate
unique problems and also provide detailed solutions. These
problems were developed by Prof. George Wiger (gwiger@chemistry.csudh.edu) at
California State University, Dominguez Hills.
Important Issues
- The pages will run properly with
Netscape 4.x and Internet Explorer 4.x or higher.
- Your screen should be set to a
minmum resolution of 1024x768. The pages will execute at lower resolutions,
but for some of them, parts of the text will overlap.
- To navigate:
- First, select a category from
the table below.
- Second, click on the
in front of the desired page.
- Several pages are not quite
ready. That fact is noted after the link.
