We first introduced the idea of a chemical change in a previous chapter. This idea can also be referred to as a chemical reaction. We use chemical equations to keep track of these chemical changes. In the first 3 sections of this chapter we introduce ideas about chemical equations that will be important to understand in later chapters. In section 5.4 and 5.5 we introduce ideas related to categorizing and predicting reactions. Categorizing and predicting reactions will both show up in later chapters. This is your first glimpse of something that will continue to be important going forward.

5.1: Word Equations
5.2: Chemical Equations
5.3: Balancing Equations
5.4: Types of Reactions
There are several ways to categorize chemical reactions, more than can possibly be covered in a single Chemistry textbook. This textbook will categorize reactions in a few places, and this is the first place where we will see it.
5.5: Predicting Reactions - Single and Double Replacement Reactions
A single-replacement reaction replaces one element for another in a compound. The periodic table or an activity series can help predict whether single-replacement reactions occur. A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds. A precipitation reaction is a double-replacement reaction in which one product is a solid precipitate. Solubility rules are used to predict whether some double-replacement reactions will occur.
5.E: Chemical Reactions (Exercises)
The following questions are related to the material covered in this chapter. For additional discussion on each topic, also check the links included in each heading.
