Introduction and Philosophy
Episode 1 of Chemistry, 2nd Edition Course
In this first lecture, Professor Cardulla explains how any student can find success in chemistry by cultivating a meaningful understanding of the concepts and quantitative thinking operations that underlie this often challenging area of study.
Basic Concepts of Quantitative Reasoning
Episode 2 of Chemistry, 2nd Edition Course
Introductory chemistry is not mysterious: It requires simple quantitative reasoning that comes naturally to most students. You learn about the types of numbers involved in chemistry and how to solve problems commonly encountered in high school chemistry.
Elements, Atoms, and the Periodic Table
Episode 7 of Chemistry, 2nd Edition Course
In the next three lectures, you cover some fundamental topics that you'll need before you can launch into your study of chemistry. You examine the basic building blocks of matter--elements and the atoms that constitute them--and you learn how to…
Advanced Stoichiometry
Episode 18 of Chemistry, 2nd Edition Course
As you move on to more advanced stoichiometry problems, you see that they can be solved using a very simple approach. You encounter three terms often applied to chemical reactions: theoretical yields, actual yields, and percent yields.
Quantitative Reasoning in Everyday Life
Episode 3 of Chemistry, 2nd Edition Course
Only a handful of important ideas must be mastered in order to be successful at solving chemistry problems. In this lecture, you review some basic guidelines for approaching any chemistry problem and try out your skills on a few sample…
An Introduction to Stoichiometry
Episode 16 of Chemistry, 2nd Edition Course
What are the quantitative relationships between the substances in a chemical reaction? The study of stoichiometry shows you how to apply your ability to balance equations to solve problems involving chemical reactions.
The SI (Metric) System of Measurement
Episode 5 of Chemistry, 2nd Edition Course
Next, you continue to lay a strong foundation for your understanding of chemistry by learning about one of the key tools you'll be using: the International System of Units (SI), or the metric system. This lecture explains why this system…
Quantitative Reasoning in Chemistry—Density
Episode 4 of Chemistry, 2nd Edition Course
Building on the ideas explored in the first three lectures, you examine a fundamental quantitative measurement in chemistry, density, and explore the real-world meaning of this measurement. You then solidify your understanding of this concept by working some basic density…
Solving Empirical Formula Problems
Episode 14 of Chemistry, 2nd Edition Course
Continue your consideration of "classic" chemistry problems with a look at empirical formulas, and examine how empirical formulas relate to molecular formulas
Ions, Compounds, and Interpreting Formulas
Episode 8 of Chemistry, 2nd Edition Course
Learn about protons, electrons, and neutrons; how ions are formed from atoms; how these ions can combine to form compounds; and how you can determine the formulas of these compounds. Some molecular substances are discussed and you are introduced to…
Writing and Balancing Chemical Equations
Episode 15 of Chemistry, 2nd Edition Course
What happens when you combine two or more elements? Through a variety of practice problems, you learn to identify when a chemical reaction has occurred, how to write chemical equations, and how to "balance" equations to conserve the atoms.
The Mole
Episode 10 of Chemistry, 2nd Edition Course
One of the most important concepts to master in an introductory chemistry course is the concept of the mole, which provides chemists with a way to "count" atoms and molecules. Learn how scientists use the mole and explore the quantitative…
Avogadro's Hypothesis and Molar Volume
Episode 12 of Chemistry, 2nd Edition Course
After mastering the mole, you move on to a related concept: the "molar volume," or the amount of space occupied by one mole. You apply this understanding of molar volume as you examine Avogadro's Hypothesis, a principle concerning the molar…
Percent Composition and Empirical Formulas
Episode 13 of Chemistry, 2nd Edition Course
In this lecture, you encounter two "classic" types of chemistry problems and learn the basic characteristics of each. The lecture concludes with several practice problems to help you master the skill of solving percent composition problems.
Stoichiometry Problems
Episode 17 of Chemistry, 2nd Edition Course
You extend your study of stoichiometry to consider more complex problems involving volume, molecules, and energy.
Solving Mole Problems
Episode 11 of Chemistry, 2nd Edition Course
By solving problems involving moles, you refine the quantitative techniques introduced in earlier lectures while increasing your familiarity with this important chemical value.
Advanced Molarity Problems
Episode 21 of Chemistry, 2nd Edition Course
You are asked to take the concepts you learned about molarity in the last two lectures and apply them to a number of unfamiliar problems. These problems offer an opportunity to test your comprehension of the concepts you've been exploring.
Converting between Systems of Measurement
Episode 6 of Chemistry, 2nd Edition Course
Now that you have established an understanding of the SI system, put your knowledge to work as you practice converting units from one system of measurement to another. You hone your conversion skills by working several sample problems.
Solving Molarity Problems
Episode 20 of Chemistry, 2nd Edition Course
Extend your understanding of molarity by solving some typical problems encountered in the high school chemistry classroom. To foster your understanding of these problems, you are asked to draw upon the quantitative reasoning skills you previously used.
An Introduction to Molarity
Episode 19 of Chemistry, 2nd Edition Course
One important idea to master in any introductory chemistry course is the concept of concentration of a solution. Here, you explore this concept, the components that make up a solution, and learn about a basic unit of measurement for concentration,…
