Chemical and physical properties help to identify substances. In this experiment, we will examine several physical and chemical properties of a number of elements and compounds. This will better help us to understand the chemical and physical changes that take place in things. This lab should give us a clear understanding of what chemist go through on a routine bases to find different chemical and physical properties. We will mix different chemicals and observe their change as they take place.
