All material covered in these lessons meet grade 7-12 standards and will prepare you to answer relevant questions found on the TExES Chemistry exam. The following are indicative of successful review of these lessons:

  • Writing balanced chemical equations
  • Determining mole ratios
  • Understanding the calculations of moles and masses
  • Making stoichiometric calculations
  • Calculating limiting reactant
  • Using equations to determine actual and percent yield
  • Comparing empirical and chemical formula
  • Defining hydrate and anhydrate

Learning these complex topics is made easy with the use of these short videos. By taking the accompanying quizzes, you can practice answering questions in the multiple-choice format that you will encounter on the TExES Chemistry 7-12 exam.

TExES Chemistry: Chemical Notations & Equations Objectives

The TExES Chemistry exam assesses your comprehension of middle to high school chemistry concepts. In the Chemical Notations & Equations chapter, you will review various chemical equations and formulas. You will find questions pertaining to these topics on the matter and energy domain of the TExES Chemistry 7-12 exam. This domain accounts for 41% of the 100-question test.

Entry-level teachers in Texas take TExES exams to achieve general educator certification as well as certification in core and specific content areas. The tests measure their understanding of the subject material and their ability to teach the concepts within each area. A minimum of 240 is required to pass a TExES exam.

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 about limiting and excess reactants and how to determine which reactant is the limiting one in a chemical reaction when given the amount of each reactant, and also 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.
