Introduction:
In this unit we will be working with chemicals and reacting them together. We will study the basic reaction types and discuss the how and why these reactions occur.
In addition, there are a few quanitities with which you need to familiarize yourself. The most important of these is the mole. Atoms are incredibly tiny. So small, in fact, that any noticable chemical reaction that takes place involves numbers of atoms in the billions of billions of billions. That's where the mole comes in. It is a chemist's versions of a dozen, only much much larger. Rather than working with numbers of atoms when performing chemical reactions, which would be cumbersome due to the huge numbers involved, we work with mole to establish the proper ratios. It is my hope that you gain a pretty good feel for what a mole is by chapter's end and become competitent in performing a few of the calculations that involve the mole.
