Ch 10: AP Chemistry: Stoichiometry and Chemical Equations: Help and Review

About This Chapter

The Stoichiometry and Chemical Equations chapter of this AP Chemistry Help and Review course is the simplest way to master stoichiometry and chemical equations. This chapter uses simple and fun videos, plus lesson quizzes and a chapter exam to ensure students learn the essentials of stoichiometry and chemical equations.

Who's it for?

Anyone who needs help learning or mastering AP chemistry material will benefit from taking this course. There is no faster or easier way to learn AP chemistry. Among those who would benefit are:

  • Students who have fallen behind in understanding how to calculate relative quantities in a gas or solution or work with hydrate calculations
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about stoichiometry and chemical equations
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How it works:

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Stoichiometry and Chemical Equations chapter exam.

  • Determining the chemical formula of hydrates from empirical data

8 Lessons in Chapter 10: AP Chemistry: Stoichiometry and Chemical Equations: Help and Review
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.

Stoichiometry: Calculating Relative Quantities in a Gas or Solution

4. Stoichiometry: Calculating Relative Quantities in a Gas or Solution

In this lesson, learn about molar volume and how to set up and make stoichiometric calculations with gases. Then learn about solution stoichiometry and how to make stoichiometric calculations with solutions.

Limiting Reactants & Calculating Excess Reactants

5. Limiting Reactants & Calculating Excess Reactants

In this lesson, you'll learn what limiting reactant and excess reactant mean and how to determine which reactant is limiting in a chemical reaction when given the amount of each reactant. You'll also discover how to calculate the amount of product produced.

Calculating Reaction Yield and Percentage Yield from a Limiting Reactant

6. Calculating Reaction Yield and Percentage Yield from a Limiting Reactant

Learn what the theoretical yield, actual yield and percent yield are. Given the limiting reactant, learn how to calculate the theoretical reaction yield, which is also known as the ideal reaction yield and percentage yield.

Calculating Percent Composition and Determining Empirical Formulas

7. Calculating Percent Composition and Determining Empirical Formulas

Learn the difference between the empirical formula and chemical formula. Learn how to calculate the percent composition of an element in a compound. Learn how, if given a percent composition, to determine the empirical formula for a compound.

Hydrates: Determining the Chemical Formula From Empirical Data

8. Hydrates: Determining the Chemical Formula From Empirical Data

Learn the definition of a hydrate and an anhydrate in this lesson. Discover how, when given experimental data, you can determine the formula of a hydrate by following simple steps that include finding the moles of hydrate and anhydrate and comparing the two to write the formula.
