Le Chatelier's Principle
In this video Paul Andersen explains how Le Chatelier's Principle can be used to predict the effect of disturbances to equilibrium. When a reversible reaction is at equilibrium disturbances (in concentration, temperature, pressure, etc.)...

Limiting Reactants and Percent Yield
Mr. Andersen explains the concept of a limiting reactant (or a limiting reagent) in a chemical reaction. He also shows you how to calculate the limiting reactant and the percent yield in a chemical reaction.

Limiting Regents and Percent Yield
Chemistry doesn't always work perfectly, silly. Molecules are left over when one thing runs out! Also we never get all of the products that we thought we might by doing the math. You gotta know about the limiting reagents and the percent...

Practice Problem: Limiting Reagent and Percent Yield
Once we get the hang of stoichiometric calculations, we get a curve ball. Limiting reagents? Not all of the reactants will react? We might not get as much product as we expect? Let's practice identifying the limiting reagent, calculating...

The Law of Conservation: Crash Course Engineering #7
Try creating something out of nothing—it's not possible! Scholars watch an engaging video, the seventh in the Crash Course Engineering series, to learn about the Law of Conservation of Mass. The video also covers the accumulation,...

Percent Yield
How do chemists know if they've done a good job performing a reaction? They use the percent yield equation! Introduce the calculation that often determines success (or otherwise) in the lab with a short video. The narrator explains...
Fuse School
Percentage Yield
Theory versus reality strikes again — only this time, scholars figure how close they come to each other. Video explains how to use the numbers for theoretical yield and actual yield to determine the percentage yield of various...
Fuse School
Theoretical Yield and Losses
Theory is when you know everything, but nothing works right. Video focuses on how to find theoretical yield and why the theory doesn't work in reality. It includes a practice problem for finding the theoretical yield and concludes with...

Limiting Reactants and Percent Yield
Viewers watch while the narrator explains limiting reactions through the familiar example of a recipe. He then describes why it is necessary to use moles to solve these problems rather than just relying on diagrams. The video ends...

Stoichiometry Practice
Build a solid understanding of reactants used and products produced in a chemical reaction with a lesson that begins with a basic stoichiometry problem and advances to questions involving limiting reactants and percent yields.
