What is the limiting reactant in the reaction shown?
A limiting reagent (or limiting reagent) of a chemical reaction is a substance that is completely consumed upon completion of a chemical reaction. This means that the reaction stops once the limiting reagent is completely consumed. As the name suggests, the limiting reagent limits the amount of product produced.
How does a limiting reactant affect a reaction?
The presence of a limiting reagent reduces the amount of products that a given reaction can form. A reagent that acts as a limiting reagent is consumed in the reaction first, essentially leaving the other reagent(s) behind. This means that the amount of product the reaction produces will depend on the limiting reagent.

What is the benefit of having a limiting reagent?
The limiting reagent for a chemical reaction is a substance that is completely consumed when the chemical reaction is completed. For example, the advantage would be that if you cancel the response in step c, the product can still be shipped.

Part 3 of 3: Calculate the interest rate. Read more about the yield percentage. The theoretical return you calculated assumes that everything went perfectly. Record the actual conduct of the experiment. If you did the experiment yourself, collect the purified product of your reaction and weigh it on a scale for calculation. Divide the actual yield by the theoretical yield.

How can a percent yield be more than 100 percent?
However, a yield of more than 100% is possible if the measured reaction product contains impurities that would make its mass greater than it would actually be if the product were pure.
