In this chapter, you'll find answers to questions including:
- What are the parts of an atom?
- What are covalent, hydrogen, ionic and polar covalent bonds?
- How is a solute different from a solvent?
- What happens during the chemical processes of osmosis and saturation?
- How do acids, bases and buffers differ?
- What are the laws of thermodynamics?
- What happens during oxidation-reduction reactions?
- How are equations used to describe chemical reactions?
1. The Atom
Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?
2. The Electron Shell
You may be familiar with the role of electrons in electrical devices, but did you know that electrons also determine the chemical reactivity of everything around you?
3. 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.
4. 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.
5. 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.
6. 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.
7. Properties of Water
Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.
8. Solutions, Solutes, and Solvents
Oh no! Your friend Ben just drank chili oil on a dare, and now his mouth is burning. Should he drink the ice water or vegetable oil to cool his mouth? Quick. Watch this lesson if you aren't sure.
9. Osmosis, Diffusion and Saturation
The cells in our bodies are in constant flux through the processes of osmosis and diffusion. Learn about how saturation levels force change, and why we're lucky they do.
10. Acids and Bases
Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.
11. 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.
12. 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.
13. 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.
14. 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.
15. Chiral vs. Achiral: Definition & Examples
Identifying chiral and achiral objects, including molecules, requires looking at many pictures, which is what you'll do in this lesson. You'll also learn the definitions of these terms and use the definitions to distinguish between chiral and achiral molecules.
16. Diprotic Acid: Definition, Formula & Examples
In this lesson, we will define polyprotic acids and diprotic acids. We will take a closer look at the mechanism of diprotic acids by studying the dissociation of carbonic acid.
17. Monoprotic Acid: Definition & Examples
Monoprotic acids are considered to be part of the Bronsted Lowry family of acids. In this lesson, explore the role of monoprotic acids in acid base reactions, and learn how to identify them in various examples.
18. Nucleophile: Definition & Examples
Nucleophiles are at the core of an important group of reactions in organic chemistry. In this lesson, we explore the definition of nucleophile as well as look at some examples to develop our understanding of the topic.
19. What is Polymerization? - Definition, Types & Examples
In this lesson, learn about the process of polymerization. Explore the two major types, common polymers, and some of the chemistry involved with this biologically and commercially important chemical reaction.
20. Cohesion in Water: Definition & Example
Cohesion in water is the property that makes water molecules attracted to one another. Learn more about why this happens and quiz yourself at the end of the video.
21. Osmosis: Definition & Examples
Water moves across cell membranes by osmosis to try to equalize the concentration of solutes on both sides of the membrane. In this lesson, learn how osmosis works and examine some examples of its importance in biology.
