About This Chapter

This chapter is designed to improve your basic understanding of chemical reactions and biochemistry. Complete the chapter's lessons and quizzes whenever you need to review these concepts for exams, class assignments, homework or projects.

Chemical Reactions & Biochemistry - Chapter Summary

This collection of fun video lessons explains basic biochemistry and chemical reaction topics. As you progress through the chapter, you'll define key chemical reaction terms and review relevant scientific laws, theories and principles. When you're finished working through the chapter, you should be equipped to:

  • Describe the effects of chemical reactions
  • Explain the significance of collision theory
  • Use the law of conservation of mass equation
  • Summarize LeChatelier's principle
  • Evaluate the role of carbon in living organisms

The chapter is entirely self-paced, and you can use any computer or mobile device to study. To help you reinforce your understanding of these concepts, we've included lesson quizzes and a chapter exam. If you wish to study offline, you can print the accompanying word-for-word lesson transcripts. Our instructors are also happy to answer any questions you may have about biochemistry and chemical reactions.

What Is a Chemical Reaction? - Definition & Effects

1. What Is a Chemical Reaction? - Definition & Effects

Sometimes, molecules look different on the outside, but only their physical appearance has changed. Other times, through chemical reactions, molecules change both inside and out, meaning both their physical and chemical properties have changed.

Collision Theory: Definition & Significance

2. Collision Theory: Definition & Significance

This lesson will define and explain collision theory and explore how it is related to chemical reactions and reaction rates. So if you've ever wondered how two particles combine to form a new product, read on!

The Law of Conservation of Mass: Definition, Equation & Examples

3. The Law of Conservation of Mass: Definition, Equation & Examples

Read about the law of conservation of mass, its role in chemistry, and its importance in the universe. Learn the equation, review examples, and test your knowledge of the material with a short quiz.

LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

4. LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

Learn how Le Chatelier's Principle describes the disruption and re-establishment of equilibrium. Learn to explain the factors that disrupt equilibrium, such as concentration, temperature, and pressure. Learn how each of these factors affects a system in equilibrium.

What Is Carbon? - Definition & Role in Living Organisms

5. What Is Carbon? - Definition & Role in Living Organisms

After watching this video, you will be able to explain what carbon is, how it is used in biological processes and why it is so vital to life on Earth. A short quiz will follow.
