About This Chapter
Chemical Bonds & Reactions - Chapter Summary
This chapter serves as a fantastic test preparation tool for individuals who want to better understand or get reacquainted with chemical bonds and reactions. Enhance your comprehension of the laws of thermodynamics, redox reactions, different types of chemical bonds and more. In no time, you will be able to:
- Define covalent and ionic chemical bonds
- Describe polar covalent and hydrogen chemical bonds
- List and discuss basic properties of chemical reactions
- Provide examples of hydrolysis and dehydration
- Share the definition of ionic compounds
- Differentiate between anabolism and catabolism
- Discuss weak acids, weak bases and buffers
Access the lessons in this chapter as short videos that average about 8 minutes each, or scroll down to view full transcripts you can read online or print out. Each lesson is accompanied by a multiple-choice quiz designed to test your knowledge of the concepts it covers. Clarify any topics you don't fully understand by sending your questions to our experts. When ready, gauge your overall knowledge of chemical bonds and reactions using our practice 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. 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.
7. 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.
8. 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.
9. 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.
10. 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.
11. 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.
