Chiral” drugs (Chapter 22). We hope that when you complete this course you too will be convinced of the importance of chemistry in today’s world. We should, however, caution you on one point. Although we will talk about many of the applications of chemistry, our main concern will be with the principles that govern chemical reactions. Only by mastering those principles will you understand the basis of the applications mentioned above. 1). 2). 3). 1 Matter and Its Classifications Matter is anything that has mass and occupies space.
