About This Chapter
Overview of Chemical Bonds and Reactions - Chapter Summary
Brush up on chemical reactions with a review of important terms such as reducing agent and oxidizing agent. Review material on how to write and balance chemical reactions. You'll also reaffirm your grasp of the following topics:
- The laws of thermodynamics
- Redox reactions
- Weak acids, weak bases and buffers
- Ionic compounds
- Polar and nonpolar covalent bonds
- Ionic and hydrogen bonds
This chapter contains a brief and engaging video lesson for each of the major focus areas. Once you've viewed a video, you can readily backtrack to any certain portions using the convenient video tags. You'll also find practice quizzes accompanying each lesson, as well as a more comprehensive chapter exam.
1. Chemical Bonds I: Covalent
Mom always said that sharing is caring. This lesson will explore how electrons affect the chemical reactivity of atoms and specifically the merits of sharing electrons.
2. Chemical Bonds II: Ionic
Did you know that the scientific name for table salt is sodium chloride? Find out how sodium and chlorine atoms come together to form your favorite seasoning.
3. Chemical Bonds III: Polar Covalent
Are you confused about how you can tell what kind of bond two atoms will form? This lesson will help you understand the difference between polar and nonpolar covalent bonds as well as how to predict how two atoms will interact.
4. Chemical Bonds IV: Hydrogen
This lesson defines and discusses important concepts behind hydrogen bonding. You'll learn when and why these bonds occur and which atoms are often involved.
5. The Laws of Thermodynamics
Learn about the first and second laws of thermodynamics. Find out how energy is generated, how it converts from one form to another, and what happens to energy in a closed system.
6. 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.
7. Basic Properties of Chemical Reactions
Learn how about the various components of a chemical reaction, and how those components function. Use this lesson to understand the basic properties of different kinds of chemical reactions.
8. Redox (Oxidation-Reduction) Reactions: Definitions and Examples
This short video will explain oxidation-reduction reactions, or redox reactions for short. The focus is on how electrons are transferred during redox reactions. Learn some neat mnemonic devices to help you remember when an atom is oxidizing or reducing.
9. Hydrolysis and Dehydration: Definitions & Examples
Water is an important component of cellular processes. Two of these processes, dehydration and hydrolysis, help your body build large molecules from small ones and break down large ones into usable components.
10. What Are Ionic Compounds? - Definition, Examples & Reactions
Ionic compounds are a common, yet special type of chemical compound. In this video lesson, you will learn about their formation and structure and see examples of compounds formed by ions.
11. Anabolism and Catabolism: Definitions & Examples
Metabolism breaks down large molecules like food into usable energy. This energy drives bodily processes critical to survival. In this video lesson, you will learn about the two forms of metabolism that break down and build up molecules and see examples of each.
12. Weak Acids, Weak Bases, and Buffers
This lesson covers both strong and weak acids and bases, using human blood as an example for the discussion. Other concepts discussed included conjugate acids and bases, the acidity constant, and buffer systems within the blood.
