About This Chapter
Who's it for?
This unit of our High School Physical Science Homeschool course will benefit any student who is trying to learn about stoichiometry and chemical equations. There is no faster or easier way to learn about physical science. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn how to make mass-to-mass stoichiometric calculations.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need a physical science curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and a Stoichiometry unit exam confirm understanding or identify any topics that require review.
Stoichiometry Unit Objectives:
- Learn how to calculate the percentage yield.
- Calculate percent composition.
- Determine the empirical formula for an element.
- Calculate the formula of a hydrate.
- Write mole-to-mole ratios and calculations.
- Calculate relative quantities in gases and solutions.
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.
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.
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.
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.
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.
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.
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.
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.
