Refresh your memory of these topics by watching the engaging video lessons in this chapter. They can be watched online and conveniently paused to allow for better comprehension. Experienced educators narrate the lessons, and you can also submit questions on chemical changes in matter to our experts. Each video's main topics can be found and accessed quickly through the timeline tags underneath the video. Self-assessment quizzes and a practice examination are also included.

MTTC Integrated Science (Elementary): Chemical Changes in Matter - Chapter Objectives

You'll complete four subareas when you sit for the MTTC Integrated Science (Elementary) examination. The fourth and final subarea covers physical science. Equal to about 25% of the test score, this subarea could include some questions on acid-base reactions, various chemical bonds, and balancing chemical equations. Test candidates have the option of taking either a paper-based version of the test or a computer-based version. There are 100 multiple-choice questions on each form, but they have different time limits. You'll be allowed four hours and 30 minutes to complete the paper test or two hours and 30 minutes to finish the computerized questions.

Acids and Bases

1. 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

2. 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

3. 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

4. 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

5. 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

6. 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

7. 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

8. 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

9. 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

10. 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

11. 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.

Rate of a Chemical Reaction: Modifying Factors

12. 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.

Equilibrium: Chemical and Dynamic

13. Equilibrium: Chemical and Dynamic

Learn the definition of chemical equilibrium and how it is dynamic. Discover what the equilibrium constant is and how it shows whether the reaction favors the reactants or products. Learn how chemists designate equilibrium in an equation and how they show the difference in reaction rate.
