Physical and Chemical Properties

The purpose of this lab is to have the opportunity to investigate the physical and chemical properties of pure chemical substances.

Procedure:
For this lab I had to get everything out first so there was no mess and so it would not be dangerous. Since I saw I was using burner fuel for this lab I had to do my lab in a safe place away from things that could catch on fire. After I got everything out I followed the procedure in my lab manual. I followed each direction perfectly so I would not make any miscalculations. After I finished I cleaned up and put everything away.
