Lecture Help Pages with Solutions-CSUDH Chemistry Department
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.
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.
