In this chapter we will learn how to write the formulas of chemical compounds, how to name chemical compounds and all about chemical reactions.


Chemical reactions are all around us, even within us. Chemical reactions involve the formation of new substances and the formation of new chemical bonds. Why do bonds form, and reactions occur? The bottom line is that reactions occur so that the products will be at a lower energy than the reactants. Bond formation involves the electrostatic attraction between two atoms.

There are many different kinds of reactions, but we will concentrate on just a few kinds of reactions in this course.

There are four fundamental observations that indicate the occurrence of a chemical reaction. We have seen gases being produced, as well as temperature changes and color changes.

Chemical reactions are represented by balanced chemical equations. Equation balancing is an acquired skill and it takes practice to do it correctly and quickly. Practice exercises. Here is a link to some chemical equations to balance in the form of some interactive games with immediate feedback. Here are some additional practice problems.

Earlier, we found out how nitric acid acts upon copper. How does nitric acid act upon other metals? Do other acids act upon copper? Do other acids act upon other metals and even salts in solution?
