Ch 22: Balancing & Using Chemical Equations

About This Chapter

Review the basics of balancing and using chemical equations by watching the video lessons in this chapter. These lessons teach you about the major types of equations and calculations and their use in chemistry.

Balancing & Using Chemical Equations - Chapter Summary

If you would like to learn more about balancing and calculating chemical equations, go through the video lessons included here. These lessons will go over specific types of equations, such as mole-to-mole ratios and double-replacement reactions, as well as essential definitions and step-by-step examples for using them. Despite the complexity of these topics, our lesson instructors go over all relevant information in a clear and comprehensive format. Specific topics covered here include:

  • Chemical reactions and steps to balancing them
  • Mole-to-mole ratios and calculations
  • Making mass-to-mass stoichiometric calculations
  • How to write and balance combustion equations
  • Rules for assigning oxidation numbers
  • Equations and examples of neutralization, single-replacement and double-replacement reactions
  • Endothermic and exothermic reactions
  • Factors that impact the rate of chemical reactions

Each video contains tags that help you locate the most important moments in the lesson corresponding to that topic's main points. The chapter also provides you with complete transcripts of each video that you can study at your own convenience. Once you feel confident in your understanding of these topics, you can answer the questions in the chapter's practice quizzes and final exam to see how much you can remember from the lessons.

Chemical Reactions and Balancing Chemical Equations

1. 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.

Mole-to-Mole Ratios and Calculations of a Chemical Equation

2. Mole-to-Mole Ratios and Calculations of a Chemical Equation

Learn what a mole ratio is and how to determine and write the mole ratio relating two substances in a chemical equation in this video lesson. Also, learn to make mole-to-mole calculations and solve problems involving moles of substances.

Mass-to-Mass Stoichiometric Calculations

3. Mass-to-Mass Stoichiometric Calculations

Learn how to set up and make mole to mass, mass to mole and mass to mass stoichiometric calculations. Learn how the ratios of moles helps you compare and make calculations. Learn how to relate mole ratios to molar mass.

Writing and Balancing Combustion Reactions

4. Writing and Balancing Combustion Reactions

Discover what a combustion reaction is as well as what reactants are needed and what products are produced. Learn to write and balance a combustion reaction. Through the concepts of bond energies, learn how to explain why combustion reactions are largely exothermic.

Assigning Oxidation Numbers to Elements in a Chemical Formula

5. Assigning Oxidation Numbers to Elements in a Chemical Formula

Learn the importance of oxidation in chemical reactions. Discover the rules for assigning oxidation numbers in both covalent compounds and ionic compounds. Learn how to assign the oxidation number for each element in a chemical formula.

Neutralization Reaction: Definition, Equation & Examples

6. Neutralization Reaction: Definition, Equation & Examples

Have you ever had a burning feeling in your stomach after eating too much spicy food? This is due to a buildup of stomach acid and can be relieved by taking an antacid. This causes a neutralization reaction, which is what we will cover in this lesson.

Single-Displacement Reaction: Definition & Examples

7. Single-Displacement Reaction: Definition & Examples

There are so many chemical reactions that occur around us that we classify them into different types. In this lesson, we will discuss single-displacement reactions, one of the main types of chemical reactions.

Double Displacement Reaction: Definition & Examples

8. Double Displacement Reaction: Definition & Examples

When a chemical reaction occurs, bonds are broken and new bonds are formed and products have a different identity from the reactants. In this lesson, we will discuss one of the main types of chemical reactions, called a double displacement reaction.

Endothermic and Exothermic Reactions

9. Endothermic and Exothermic Reactions

Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.

Rate of a Chemical Reaction: Modifying Factors

10. Rate of a Chemical Reaction: Modifying Factors

Why are some reactions much faster than others? Is it possible to change how fast a reaction occurs? In this lesson, you will learn what the rate of a chemical reaction is. You will also discover how factors such as temperature, concentration, surface area, and catalysts impact reaction rates.
