Chemistry

__//**Welcome to Regents Chemistry!**//__

In this class we will learn all the basics theories and concepts that modern chemistry is based on, and while doing so prepare the class to take the NYS Chemistry regents in June.

On this page I will be posting all class lectures in power point form, as well as homework that is given.

All students must be very careful to keep all notes, home works, and labs, in an organized way so that they can be checked up on periodically during the course of the year.
