Ch 10: MTTC Physical Science: Chemical Reactions

About This Chapter

Review important material in this chapter on chemical reactions in preparation for the MTTC Physical Science test. The video lessons and lesson transcripts give you an effective review of related subject matter.

MTTC Physical Science: Chemical Reactions - Chapter Summary

Get the chemicals in your brain bubbling as you remember the processes involved in chemical reactions. The chemistry section is one of the largest sections on the MTTC Physical Science exam, and to be ready for such a key section, you should be familiar with the following topics:

  • Kinds of common chemical reactions
  • Oxidation-reduction reactions
  • Le Chatelier's principle
  • Electrochemistry and chemical thermodynamics
  • Neutralization and equilibrium
  • Modifying factors affecting chemical reaction rates
  • Exothermic and endothermic reactions
  • Reaction coordinate diagrams

There are many details to go over in this chapter about chemical reactions, and that is why our instructors have split up this chapter into multiple lessons. We understand that in a refresher course scenario, you may only need to brush up on a few topics, so we try to break up our chapters into one main topic per lesson. In preparation for the MTTC Physical Science exam, use the lesson menu to search for the titles you need to review. Each lesson only takes about five minutes to watch, so going through several lessons in one sitting is absolutely doable. For topics you know fairly well, you can use the transcripts and skim through the keywords as a way to keep all the terminology fresh in your mind for the assessment.

Redox (Oxidation-Reduction) Reactions: Definitions and Examples

1. 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.

Aliphatic Hydrocarbons: Definition & Properties

2. Aliphatic Hydrocarbons: Definition & Properties

Learn about aliphatic hydrocarbons and discover where you can find these types of compounds in everyday life. Understand the definition and properties of aliphatic hydrocarbons.

Neutralization and Acid-Base Reactions

3. 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.

Common Chemical Reactions and Energy Change

4. Common Chemical Reactions and Energy Change

This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.

Endothermic and Exothermic Reactions

5. 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.

Rate of a Chemical Reaction: Modifying Factors

6. 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

7. 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.

LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

8. LeChatelier's Principle: Disruption and Re-Establishment of Equilibrium

Learn how Le Chatelier's Principle describes the disruption and re-establishment of equilibrium. Learn to explain the factors that disrupt equilibrium, such as concentration, temperature, and pressure. Learn how each of these factors affects a system in equilibrium.

Electrochemical Cells and Electrochemistry

9. Electrochemical Cells and Electrochemistry

Learn to identify the parts of and be able to describe an electrochemical cell, including the electrolyte, electrodes, anodes, and cathodes. Learn how to make a homemade lemon battery and how to diagram an electrochemical cell that will light a light bulb.

Electrochemistry: Free Energy and Cell Potential Energy

10. Electrochemistry: Free Energy and Cell Potential Energy

Our modern lives are totally dependent on electricity. In this lesson, we learn about electricity spontaneously produced by electrochemical cells or batteries. We make the link between the potential energy they produce and Gibbs free energy.

Chemical Thermodynamics: Definition & Principles

11. Chemical Thermodynamics: Definition & Principles

Learn about chemical thermodynamics and explore some of its basic principles, including systems and the laws of thermodynamics. See how well you grasp the principles at the end of the lesson by taking a quick quiz.

Analyzing Energy With a Reaction Coordinate Diagram

12. Analyzing Energy With a Reaction Coordinate Diagram

In this lesson, we will learn about reaction coordinate diagrams and how they help us analyze energy in reactions. We will learn what the graph means and how to interpret it.
