Understanding Yields in Stoichiometry

What are the three types of yield discussed in the video?

• Theoretical, Actual, and Percent Yield

• Theoretical, Practical, and Percent Yield

• Actual, Practical, and Percent Yield

• Theoretical, Actual, and Practical Yield

In the ice cream cone analogy, what is the theoretical yield?

• Two double scoop ice cream cones

• Three double scoop ice cream cones

• Six double scoop ice cream cones

• Four double scoop ice cream cones

Why is the actual yield often less than the theoretical yield?

• Because of perfect lab conditions

• Due to loss of product during the process

• Because the theoretical yield is always underestimated

• Due to excess reactants

What is the actual yield in the ice cream cone example?

• One double scoop ice cream cone

• Two double scoop ice cream cones

• Three double scoop ice cream cones

• Four double scoop ice cream cones

How is percent yield calculated?

• Theoretical yield divided by actual yield times 100

• Theoretical yield minus actual yield times 100

• Actual yield divided by theoretical yield times 100

• Actual yield plus theoretical yield times 100

What was the percent yield in the ice cream cone example?

• 50%

• 66.67%

• 75%

• 80%

What is the first step in solving a classroom problem on yield?

• Convert grams to moles

• Determine the actual yield

• Ensure the equation is balanced

• Calculate the percent yield

In the classroom problem, what is the molar mass of oxygen gas used?

• 16.00 grams per mole

• 32.00 grams per mole

• 28.00 grams per mole

• 44.00 grams per mole

What is the theoretical yield of oxygen gas in moles in the classroom problem?

• 0.227 moles

• 0.238 moles

• 0.405 moles

• 0.341 moles

What is the percent yield of oxygen gas in the classroom problem?

• 80%

• 70%

• 60%

• 90%
