Ch 16: Holt McDougal Modern Chemistry Chapter 16: Reaction Energy

About This Chapter

The Reaction Energy chapter of this Holt McDougal Modern Chemistry Companion Course helps students learn the essential chemistry lessons of reaction energy. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Reaction Energy textbook chapter.

How It Works:

  • Identify the lessons in Holt McDougal Modern Chemistry's Reaction Energy chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the reaction energy topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Thermochemical equations
  • Heat and its applications

How to Calculate Specific Heat Capacity for Different Substances

1. How to Calculate Specific Heat Capacity for Different Substances

This lesson describes specific heat capacity and explains how the specific heat capacity of water helps to maintain a relatively constant temperature in nature. Learn how to identify the specific heat capacity of other common materials and how to calculate specific heat capacity with an experiment.

Endothermic and Exothermic Reactions

2. 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.

Second Law of Thermodynamics: Entropy and Systems

3. Second Law of Thermodynamics: Entropy and Systems

In this lesson, we'll learn about the second law of thermodynamics. By studying this law, you'll understand how energy works and why we're all moving towards eventual chaos and disorder.

Thermochemical Equations

4. Thermochemical Equations

In this lesson we will learn about thermochemical equations and how we use them to tell what happens to energy in equations and if the reaction is endothermic or exothermic.

Hess's Law: Definition, Formula & Examples

5. Hess's Law: Definition, Formula & Examples

In this lesson, we learn about Hess's Law and how to use enthalpy of formation and enthalpy of combustion to calculate the change in enthalpy using Hess's law.
