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 reactions. Video is the 19th in a 29-part series.

Instructional Ideas

• Research more than one industry to find its standard for percentage yield and what is considered acceptable
• Debate if the industry standard set for amount of waste should vary based on the industry and the type of waste, i.e. is it okay for prescription manufacturers to have a lower rate when the waste is water than for the energy manufacturers when the waste is carbon dioxide?

Classroom Considerations

• Requires prior knowledge of moles, conservation of mass, atomic mass, and chemical equations

Pros

• Highlights the formula multiple times during the video
• Includes two examples with prompts to pause and attempt solving independently

Cons

• None
