what is used up in and stops a chemical reaction?\npercent yield\nlimiting reactant\ntheoretical…

Brief Explanations:

In a chemical reaction, the limiting reactant is the substance that is completely consumed first. Once it is used - up, the reaction stops as there is no more of this reactant to continue the reaction. Percent yield is a comparison of actual and theoretical yields, theoretical yield is the maximum amount of product possible, and excess reactant is left over after the reaction.

Answer:

B. limiting reactant
