Ch 29: Chemical Symbols, Formulas & Reactions

About This Chapter

Let us help you boost your knowledge of the formulas, reactions and symbols used in chemistry with this chapter. Use the lessons and quizzes as a convenient, flexible way to prepare and study for tests or placement exams.

Chemical Symbols, Formulas & Reactions - Chapter Summary

In this chapter, the short-hand way to identify a compound on the periodic table, its chemical symbol, is explained. The information provided by chemical formulas is detailed, as well as how to balance chemical equations using the law of conservation of matter. One type of chemical reaction called a combination reaction is defined with examples.

While making your way through the videos, you will also learn how oxidation-reduction reactions, or redox reactions for short, transfer electrons. These lessons will prepare you to:

  • Identify common elements on the periodic table with their chemical symbol
  • Differentiate between chemical formulas
  • Write both formula and word equations
  • Explain how combination reactions work
  • Use handy mnemonic devices to help you remember if an atom is reducing or oxidizing

Test your knowledge of the above topics by taking our short quizzes. If you need help as you work through the chapter, contact one of our instructors for help. These study materials are accessible to you at any time, 24 hours a day. Use each lesson's printable transcript to make a copy you can study offline as well.

Chemical Symbol: Definition & Examples

1. Chemical Symbol: Definition & Examples

In this lesson, you will learn that a chemical symbol is a short-hand way to represent an element and each element on the periodic table has a unique chemical symbol. You'll become familiar with identifying some common elements by their chemical symbol.

What is a Chemical Formula? - Definition, Types & Examples

2. What is a Chemical Formula? - Definition, Types & Examples

Chemical formulas provide a lot of information about chemical substances, such as how many and what atoms they are made of, as well as the way the atoms are arranged. In this lesson, we'll discuss the different types of chemical formulas.

Chemical Reactions and Balancing Chemical Equations

3. 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.

Combination Reaction: Definition & Examples

4. Combination Reaction: Definition & Examples

There many types of chemical reactions. In a combination reaction, you can predict the product if you know what goes into it. Find out more about combination reactions and see some examples.

Redox (Oxidation-Reduction) Reactions: Definitions and Examples

5. 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.
