Ch 8: OAE - Integrated Science: Chemical Changes in Matter

About This Chapter

Every prospective Ohio science teacher of adolescents must take the OAE Integrated Science exam. This exam will have questions on the chemical changes in matter. Let us help you review these important concepts with our fun and engaging study guide.

OAE - Integrated Science: Chemical Changes in Matter - Chapter Summary

This chapter reviews the concepts of chemical changes in matters as well as writing these changes corresponding chemical equations. In preparation for the exam, go over concepts that include acids and bases, bonding, redox, percipitation reactions, and stoichiometry. Each of these lessons also features information on how to write and balance these same chemical reactions as equations. By the end of the chapter, you will have reviewed:

  • Pure and Applied Chemistry
  • Coordination chemistry
  • Bases, acids and neutralization
  • Redox reactions
  • Precipitation reactions
  • Oxidation numbers
  • A comparison between exothermic and endothermic reactions
  • Ionic equations
  • Stoichiometric calculations
  • Chemical reaction rates
  • Chemical and dynamic equilibrium

You can watch the interesting video lessons with our energetic instructors and then test your comprehension with the lesson quizzes afterwards. These lesson quizzes are very similar to the ones you will see on your upcoming exam. Practicing with these similarly formatted questions will give you the familiarity you need to succeed.

OAE Integrated Science: Chemical Changes in Matter Chapter Objectives

This chapter of the study guide links to the physical science domain of the 3-hour-long, computer-based OAE Integrated Science exam. The domain splits into six different subtopics. This chapter connects to the second subtopic, which examines your knowledge of chemical reactions and chemical bonding. By reviewing this chapter you will be preparing yourself to demonstrate your competencies in these areas.

The exam has three other domains: earth science, life science, and the nature of science. The physical science domain is the most sizable one; this section account for 37% of the 150 multiple-choice questions.

Overview of the International Union of Pure and Applied Chemistry

1. Overview of the International Union of Pure and Applied Chemistry

The International Union of Pure and Applied Chemistry is an important organization within the chemistry world. In this lesson we will go over what this organization does and why it is important.

Acids and Bases

2. Acids and Bases

Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.

Coordination Chemistry: Bonding in Coordinated Compounds

3. Coordination Chemistry: Bonding in Coordinated Compounds

Discover what a coordinated compound is. Understand how bonding occurs in coordinated compounds and some of the possible shapes coordinated compounds can be. Learn the uses in nature and industry for coordinated compounds.

Precipitation Reactions: Predicting Precipitates and Net Ionic Equations

4. Precipitation Reactions: Predicting Precipitates and Net Ionic Equations

Learn what a precipitate is and predict when it will form in an aqueous chemical reaction, usually a double-replacement reaction. Learn what an ionic equation is, how it differs from a net ionic equation and how to write a net ionic equation.

Assigning Oxidation Numbers to Elements in a Chemical Formula

5. Assigning Oxidation Numbers to Elements in a Chemical Formula

Learn the importance of oxidation in chemical reactions. Discover the rules for assigning oxidation numbers in both covalent compounds and ionic compounds. Learn how to assign the oxidation number for each element in a chemical formula.

Neutralization and Acid-Base Reactions

6. Neutralization and Acid-Base Reactions

From this lesson, you will understand the neutralization process between acids and bases. Learn how a hydroxide ion from a base reacts with a hydronium ion from an acid to neutralize each other and form water. Discover what conjugate acids and bases are and what the definition of amphoteric is.

Redox (Oxidation-Reduction) Reactions: Definitions and Examples

7. Redox (Oxidation-Reduction) Reactions: Definitions and Examples

This short video will explain oxidation-reduction reactions, or redox reactions for short. The focus is on how electrons are transferred during redox reactions. Learn some neat mnemonic devices to help you remember when an atom is oxidizing or reducing.

Balancing Redox Reactions and Identifying Oxidizing and Reducing Agents

8. Balancing Redox Reactions and Identifying Oxidizing and Reducing Agents

Learn how to identify an oxidizing agent and a reducing agent and how the loss or gain of electrons applies to each one. Learn the relationship between an oxidized or reduced substance and the oxidizing or reducing agent associated with it. Discover what steps to take to balance a redox reaction.

Basic Properties of Chemical Reactions

9. Basic Properties of Chemical Reactions

Learn how about the various components of a chemical reaction, and how those components function. Use this lesson to understand the basic properties of different kinds of chemical reactions.

Endothermic and Exothermic Reactions

10. Endothermic and Exothermic Reactions

Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.

Avogadro's Number: Using the Mole to Count Atoms

11. Avogadro's Number: Using the Mole to Count Atoms

How do we move from the atomic world to the regular world? Because atoms are so tiny, how can we count and measure them? And what do chemists celebrate at 6:02 AM on October 23rd each year? In this lesson, you will be learning how Avogadro's number and the mole can answer these questions.

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

12. 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.

Stoichiometry: Calculating Relative Quantities in a Gas or Solution

13. 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.

Mass-to-Mass Stoichiometric Calculations

14. 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.

Rate of a Chemical Reaction: Modifying Factors

15. Rate of a Chemical Reaction: Modifying Factors

Why are some reactions much faster than others? Is it possible to change how fast a reaction occurs? In this lesson, you will learn what the rate of a chemical reaction is. You will also discover how factors such as temperature, concentration, surface area, and catalysts impact reaction rates.
