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.

Basic Properties of Chemical Reactions

2. 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.

Common Chemical Reactions and Energy Change

3. Common Chemical Reactions and Energy Change

This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.

Endothermic and Exothermic Reactions

4. 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

5. 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.
