# Ch 14: ORELA Chemistry: Stoichiometry & Chemical Equations

As part of your preparations for the ORELA Chemistry exam, brush up on your knowledge of stoichiometry and chemical equations when you view the engaging online video lessons in this chapter. The lessons include multiple-choice pop-up quizzes that will evaluate your retention of the material.

## ORELA Chemistry - Stoichiometry and Chemical Equations - Chapter Summary

This chapter outlines the fundamentals of stoichiometry and could enhance your ability to perform stoichiometric calculations. Some of the included examples will allow you to practice solving stoichiometry problems in four steps or write the ratios for balanced equations. In other lessons, you'll be able to learn more about the use of Avogadro's number and the process of calculating the percent yield of a particular chemical reaction. Watching these online videos before you take the ORELA Chemistry examination might help you with:

• Learning to balance and write chemical equations
• Making mole-to-mole and mass-to-mass calculations
• Describing molar volume and calculating relative quantities
• Exploring limiting reactants and calculating theoretical reaction yield
• Discovering how to determine an empirical formula
• Calculating the formula of a hydrate

Use these animated video lessons to review these topics or to learn new details about stoichiometry and chemical equations. Study at your own pace and use the ask-a-question feature in order to receive personalized support. In addition to video tags for navigating the lessons, you'll find written transcripts and handy worksheets that can be printed and studied in your spare time. The self-assessment quizzes and the practice chapter examination could prepare you for some of the questions on the ORELA Chemistry examination.

### ORELA Chemistry - Stoichiometry and Chemical Equations Objectives

The Stoichiometry and Solutions content domain is the fifth and last of the ORELA Chemistry examination's five content domains. Your understanding of stoichiometry and your familiarity with topics such as net ionic equations and limiting reactant yield will be assessed during this domain, which is worth approximately 18% of the entire assessment score. You must adhere to a three-hour-and-45-minute time limit when sitting for the computer-administered examination. There are 150 multiple-choice questions on the overall examination.
