The limiting reactant tells you how much of each reactant is formed. If you use the excess material a false answer for the calculated products will come out.

Why is it necessary to determine if a reactant is is a limiting reagent in a reaction?

The limiting reagent is entirely used at the end of a chemical reaction.


What is the definetions of limiting reactant in chemistery?

In a chemical reaction the limiting reactant is the reactant that there is the least of in the reaction; it determines the amount of product formed. In a chemical reaction it is the reactant that gets completely "used up"


After a chemical reaction starts when will a chemical reaction end?

When the limiting reactant is completely used up. A limiting reactant is the reactant that determines the amount of product. To determine this use the balanced chemical reaction with the masses of the reactants to determine the moles of product formed. The reactant that forms the least amount of product will be the limiting reactant.


How limiting reactant control a reaction?

Using an excess of another reactant limits a reactant.


Define limiting reactant?

In a chemical reaction the limitting reactant is also know as limiting reagent.it is the substance which is totally consumed when the chemical reaction is complete.the reacton can not proceed without it.


What is the reactant called that gets used up first?

Why is it necessary to determine if a reactant is a limiting reagent in a reaction?

The amount of product formed will be limited by the amount of the limiting reagent.


Why is necessary to determine if a reactant is limiting reagent in a reaction?

Why is it necessary to determine if a reactant is limiting reagent in reaction?

The amountof product form will be limited by the amount of the limiting reagent


Examples of How a limiting reactant controls the amount of product formed in a chemical reaction?

limiting reactant controls the amount of product formed in a chemical reaction because it is found in smaller quantity and consumed earlier .Due to this reason the chemical reaction stops and no additional product is formed
