8 Lessons in Chapter 15: Holt Physical Science Chapter 15: Chemical Compounds
Covalent Compounds: Properties, Naming & Formation

1. Covalent Compounds: Properties, Naming & Formation

Learn about covalent bonds, how covalent compounds are formed and the properties inherent to covalent compounds, such as low melting and boiling points, in this lesson. Also, learn what rules to follow to name simple covalent compounds.

Ionic Compounds: Formation, Lattice Energy and Properties

2. Ionic Compounds: Formation, Lattice Energy and Properties

In this lesson, you'll learn about ionic compounds and how they form. Additionally, you'll learn the properties of ionic compounds, such as their high melting and boiling points, their ability to conduct electricity, and the fact that they form crystals.

Acids and Bases

3. 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.

Weak Acids, Weak Bases, and Buffers

4. 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.

Neutralization and Acid-Base Reactions

5. Neutralization and Acid-Base Reactions

From this lesson, you will understand the neutralization process between acids and bases. Learn how a hydroxide ion from a base reacts with a hydronium ion from an acid to neutralize each other and form water. Discover what conjugate acids and bases are and what the definition of amphoteric is.

The pH Scale: Calculating the pH of a Solution

6. The pH Scale: Calculating the pH of a Solution

Learn the history of the pH scale, how to describe it and why it is used by scientists. Discover how to calculate the pH of an acid or base solutions given either the hydroxide ion concentration or the hydronium ion concentration. Learn how to start with the pH and calculate the hydroxide and hydronium ion concentrations.

Organic Molecules: Alkanes, Alkenes, Aromatic Hydrocarbons and Isomers

7. Organic Molecules: Alkanes, Alkenes, Aromatic Hydrocarbons and Isomers

Learn more about carbon and hydrogen and see how these atoms come together to form distinct molecules. Also, study the difference between saturated and unsaturated molecules.

Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids

8. Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids

Bacterial cells have complex macromolecules built from simple molecules. In this lesson, we will look at the major elements in the building blocks of proteins, nucleic acids, carbohydrates, and lipids.
