Does the term "chemical reaction" bring to mind an image like this one? In the picture, a chemist is mixing chemicals
in a lab. Many chemical reactions take place in labs. However, most chemical reactions do not. Where do they occur?
They happen in the world all around you. They even happen inside your own body. In fact, you would not be alive
if it were not for the many chemical reactions that take place inside your cells. In this chapter, you will learn about
chemical reactions, including two very important reactions that take place in living things.
