Chemical Equations & Stoichiometry - Chapter Summary

Going through these engaging video lessons on chemical equations and stoichiometry is a great way to enhance your knowledge of limiting reactants and how to calculate percentage yield. Expert instructors also help you understand the balanced chemical equation. By the end of the chapter, you should be ready to:

  • Discuss mole-to-mole ratios
  • Provide an example of a chemical equation
  • Explain how to write a balanced chemical reaction
  • Perform a mass-to-mass stoichiometric calculation
  • Describe how to calculate excess reactants
  • Use empirical data to determine the chemical formula of hydrates
  • Calculate relative quantities in a solution
  • Discuss percent composition and empirical formulas

Our instructors use an easy to comprehend teaching style that simplifies otherwise complex information to ensure your comprehension. A short self-assessment quiz is available for each lesson in this chapter, and if you find yourself wanting to revisit a topic covered in a lesson, you can click the video tag to go straight to that topic.

What is a Chemical Equation? - Definition & Examples

1. What is a Chemical Equation? - Definition & Examples

In this lesson, you will learn how chemical equations are used to represent chemical reactions. You will learn that there are many pieces of information provided in a chemical equation, and you will gain an understanding of how to interpret chemical equations.

Balanced Chemical Equation: Definition & Examples

2. Balanced Chemical Equation: Definition & Examples

A chemical equation shows the chemical formulas of substances that are reacting and the substances that are produced. The number of atoms of the reactants and products need to be balanced. In this lesson, we will discuss balancing chemical equations.

Writing Balanced Chemical Reactions

3. Writing Balanced Chemical Reactions

Chemical reactions are occurring around us all the time. We express these reactions in chemical equations, which must be balanced, meaning that while both sides may not have the same arrangement of atoms, they will have the same number and type.

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

4. 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

5. 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

6. 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

7. 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

8. 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

9. 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

10. 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.
