Was this helpful?People also askWhat is limiting reagent?What is limiting reagent?Key PointsThe limiting reagent is the reactant that is used up completelyGiven the balanced chemical equation that describes the reaction,there are several ways to identify the limiting reagent.One way to determine the limiting reagent is to compare the mole ratios of the amounts of reactants usedThe limiting reagent can also be derived by comparing the amount of products that can be formed from each reactant.Limiting Reagents | Introduction to ChemistrySee all results for this questionHow to find limiting reagents?How to find limiting reagents?In order to find the limiting reagents,excess reagents,and products in this reaction,you need to do the following:Balance the equation.Determine the limiting reagent if 100 g of each reagent are present at the beginning of the reaction.Identify the excess reagent,as well as how many grams of the excess reagent will remain when the reaction reaches completion.More itemsCalculate Limiting Reagents, Excess Reagents, and Products in ChemicaSee all results for this questionWhat is a limiting reagent problem?What is a limiting reagent problem?A limiting reactant problem where you have to convert back and forth between grams and moles. Limiting reactant or limiting reagent is the first reactant to run out in a chemical reaction,and it limits the amount of product you can make. In this advanced limiting reactant (limiting reagent) practice problem,..Limiting Reactant Practice Problem (Advanced) - YouTubeSee all results for this questionHow to do limiting reagent problems?How to do limiting reagent problems?Solution. To determine the limiting reactant, calculate the amount of product formed by each reactant. The reactant the produces the least amount of product is the limiting reactant. The sodium hydroxide formed less product than the phosphoric acid. This means the sodium hydroxide was the limiting reactant and 48 grams..Limiting Reactant Problems in Chemistry - ThoughtCoSee all results for this questionFeedback

Oct 26, 2010A limiting reagent is exactly what it says on the tin - whatever reagent is going to limit your reaction. In this case it's clear that it's going to be oxygen as you will need three times as much oxygen as hydrazine and in this case you don't even have a 1:1 ratio so your reaction will run out of oxygen long before it runs out of hydrazine.[PDF]
