Front

What is the theoretical yield?

Back

The maximum amount of product possible in a reaction, assuming perfect conditions.

Front

What is a limiting reactant?

Back

The reactant that is completely consumed in a reaction, limiting the amount of product formed.

What does a percent yield of over 100% indicate?

Back

It indicates that there may have been an error in measurement or that impurities are present.

Front

In a reaction, if 5 moles of A react with 3 moles of B, which is the limiting reactant if the reaction requires 2 moles of A for every mole of B?

Back

B is the limiting reactant.

Front

What is the actual yield?

Back

The amount of product actually obtained from a chemical reaction.

What is stoichiometry?

Back

The calculation of reactants and products in chemical reactions.
