Ch 55: MTEL Middle School Math/Science: Stoichiometry & Chemical Equations

About This Chapter

The lessons in this chapter will present the math calculations commonly found in chemistry, formally known as stoichiometry. Our knowledgeable instructors will guide you each step of the way as you get set for the MTEL Middle School Math/Science test.

MTEL Middle School Math/Science: Stoichiometry & Chemical Equations - Chapter Summary

This chapter covers the basics of chemical reactions and introduces common chemistry calculations. Lessons prepare you for MTEL Middle School Math/Science test questions on topics such as:

  • Chemical reactions
  • Balancing chemical equations
  • Mole-to-mole ratios
  • Mass-to-mass calculations
  • Calculations with gases and solutions
  • Reactants and their effects on reactions
  • Yield calculations
  • Empirical formula vs. chemical formula
  • Hydrates and anhydrates
  • Determining formulas from experimental data

The videos in these lessons will demonstrate the calculations step-by-step as you progress through this Stoichiometry & Chemical Equations chapter. Review as much as you like, and if it gets confusing, just ask for help. The review questions at the end of the lessons are a great way to ensure you are prepared as you move on to the other topics throughout the chapter. But remember, do the math without a calculator; they are not allowed during the test.

MTEL Middle School Math/Science: Stoichiometry & Chemical Equations Objectives

The MTEL Middle School Math/Science exam is designed to test your mastery of the science and math topics commonly taught at the middle school level when applying for teacher licensure in the state of Massachusetts. The information found in the Stoichiometry & Chemical Equations chapter are part of Subarea VII - Chemistry, which makes up approximately 8% of the MTEL Middle School Math/Science exam. The chapter explains and demonstrates the math involved in chemistry as well as an introduction to reactions and chemical equations, helping you prepare for the Chemistry questions found on the MTEL Middle School Math/Science exam. The self-assessment quizzes are a great way to review material or to ensure mastery as you study for your licensure test.

The MTEL Middle School Math/Science test is 100 multiple-choice questions and 2 open-response assignments, one exploring math concepts and the other exploring science. Your test score is is based 80% on multiple choice responses and10% on each of the two open-response questions, totaling 100%. It is computer-based, and you have four hours to complete the exam.

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.
