Tomorrow we’ll be starting our first lab describing the reaction of a quirky metal with a very powerful base. Please make sure to have your lab notebook with you (if you still need to order one, head here or here). As we discussed today, these notebooks will become very important as we move through the [...]

By 8am Wednesday (September 8, 2010 8:00 AM EST), find and blog about a compound that you think is incredibly interesting.

Today we continued our studies of Antoine Lavoisier and his importance to chemistry (and many other areas). Here is a link to the reading that we covered in class on the life of Lavoisier. Additionally, here’s a link to the Wikipedia article we discussed which has a couple of fantastic pictures relating to Mr. Lavoisier [...]

Here are the notes we started covering in class on Tuesday and will finish up on Wednesday (your homework is on the last slide): If you have trouble finding points for your homework, try clicking on Antoine Lavoisier’s and Dmitri Mendeleyev’s names at the top of slides 9 and 10. Those links will take you [...]
