About This Chapter

As you study the lessons in this chapter, you will reinforce your knowledge on chemical compounds and reactions. By completing the activities in this chapter, you will have a much deeper understanding of the concepts that are reviewed in this chapter.

Chemical Compounds & Reactions- Chapter Summary

This chapter will give you material you need to know about chemical compounds and reactions. Watching our video lessons will present you with the different types of chemical reactions that are seen in science. Going through this chapter will help you recall the following topics:

  • Examples of chemical compounds
  • Conservation of matter law
  • Five typical chemical reactions
  • How enthalpy determines the type of reaction
  • Factors that affect the rate of a reaction
  • Relationship between chemical reactions and reaction rate and equilibrium

These lesson videos are taught by our expert instructors who can answer any questions you might have. In addition to watching the lessons, you can further fortify your retention of the material presented by taking lesson quizzes. When you get the immediate results of these quizzes, you have the chance to go back into the lessons and review anything you have missed by the video tags and transcripts.

What Is a Chemical Compound? - Definition & Examples

1. What Is a Chemical Compound? - Definition & Examples

Very few single chemical elements are encountered in everyday life. In this lesson, you will learn about chemical compounds through some examples to gain a better understanding of what they are and how they form.

Chemical Reactions and Balancing Chemical Equations

2. Chemical Reactions and Balancing Chemical Equations

In this lesson, you'll learn how to balance a chemical reaction equation using the conservation of matter law. You'll also learn how to write both word and formula equations, what the subscripts after a letter mean and what the numbers in front of compounds mean.

Common Chemical Reactions and Energy Change

3. Common Chemical Reactions and Energy Change

This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.

Endothermic and Exothermic Reactions

4. Endothermic and Exothermic Reactions

Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.

Rate of a Chemical Reaction: Modifying Factors

5. Rate of a Chemical Reaction: Modifying Factors

Why are some reactions much faster than others? Is it possible to change how fast a reaction occurs? In this lesson, you will learn what the rate of a chemical reaction is. You will also discover how factors such as temperature, concentration, surface area, and catalysts impact reaction rates.

Chemical Kinetics, Reaction Rate Constant & Equilibrium Constant

6. Chemical Kinetics, Reaction Rate Constant & Equilibrium Constant

Are formulas, rate constants, and chemical reactions getting you down? Don't worry, this lesson will explain how reaction rate and equilibrium constants are related to chemical reactions.
