About This Chapter
Basic Concepts of Chemistry - Chapter Summary
In these lessons, you'll learn about basic concepts of chemistry. Topics covered include early atomic theory and Gay-Lussac's law. After completing the chapter, you should be prepared to:
- Assess accuracy vs. precision in chemistry
- Understand dimensional analysis in chemistry
- Explain early atomic theory according to Dalton, Thomson, Rutherford, and Millikan
- Discuss the laws of conservation, definite proportions, multiple proportions, and reciprocal proportion
- Interpret gas pressure and temperature relationship according to Gay-Lussac's law
Our subject matter experts present the information in these short videos in an engaging manner. The video timeline can be used to jump straight to the topics of greatest interest. A brief multiple-choice quiz is available for each lesson. You can also print the lesson quizzes out as worksheets.
1. Accuracy vs. Precision in Chemistry: Definitions & Comparisons
Accuracy and precision are words that are often used interchangeably, but in science they have very specific and different definitions. In this lesson, we will explore the ways in which these terms are used in chemistry as well as explore comparisons and differences.
2. What Is Dimensional Analysis in Chemistry? - Definition, Method & Practice Problems
Learn about units of measurement in chemistry and the common metric prefixes you will see used with those units. Practice converting units of measurement using Dimensional Analysis.
3. Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan
Imagine firing a bullet at a piece of tissue paper and having it bounce back at you! You would probably be just as surprised as Rutherford when he discovered the nucleus. In this lesson, we are going to travel back in time and discuss some of the major discoveries in the history of the atom.
4. The Law of Conservation of Mass: Definition, Equation & Examples
Read about the law of conservation of mass, its role in chemistry, and its importance in the universe. Learn the equation, review examples, and test your knowledge of the material with a short quiz.
5. The Law of Definite Proportions: Definition & Examples
Have you ever had to double a baking recipe? The trick is to always keep the ingredient proportions the same as in the original recipe. This cooking principle follows the Law of Definite Proportions in chemistry, which is the focus of this lesson.
6. Law of Multiple Proportions: Definition & Examples
We often deal with different combinations of the same things every day. The same thing goes for chemistry, where elements can combine to form two or more compounds. This is possible according to the law of multiple proportions, which we will discuss in this lesson.
7. Law of Reciprocal Proportion: Definition & Examples
Jeremias Richter discovered the Law of Reciprocal Proportion in the late 18th century. In this lesson we will learn what this law is and how it is used by looking at some examples.
8. Gay-Lussac's Law: Gas Pressure and Temperature Relationship
You may know that you aren't supposed to put an aerosol can in a fire because it could explode, but do you know why? In this lesson, we will explain Gay-Lussac's law, which shows the relationship between the temperature and pressure of a gas.
