Stoichiometry/Limiting/Excess/Percent Yield

Front

What does percent yield indicate?

Back

The efficiency of the lab.

Front

Theoretical yield = 73g; Actual yield = 62g. Calculate the percent yield.

Back

85%.

Front

What is a limiting reactant?

Back

The reactant that determines how much product can be made.

Front

True or False: Some product may be lost during filtering causing your actual yield to be less than your theoretical yield.

Back

True.

Front

Theoretical yield = 13g; Actual yield = 12.5g. What is the percent yield?

Back

96%.

Front

Define stoichiometry.

Back

The calculation of reactants and products in chemical reactions.

Front

What is the excess reactant?

Back

The reactant that is not completely consumed in a reaction.

Front

How do you calculate percent yield?

Back

(Actual Yield / Theoretical Yield) x 100.

Front

What is theoretical yield?

Back

The maximum amount of product that can be produced from a given amount of reactants.

Front

What is the significance of a low percent yield?

Back

It indicates that the reaction was not efficient.
