With any chemical reaction you have reactants and products, for this question I'll use the example of the formation of water from it's parts, Hydrogen and Oxygen. The equation would look like this:
2H2 (g) + O2 (g) -> 2H2O (l)
Let's say you start out with 3 moles of Hydrogen and 1 mole of Oxygen. From the reaction you can see that for every mole of O2 that reacts, 2 moles of H2 are reacted. This means that after your mole oxygen reacts, you are still left with a mole of excess Hydrogen. Thus, Hydrogen is considered the excess reactant, and Oxygen is considered the limited reactant.
In short, the limited reactant is whichever reactant you will use up in the reaction first.
What else can I help you with?
Is AgNO3 as the limited reactant or NaCl?
To determine the limiting reactant between AgNO3 and NaCl, you need to compare their stoichiometry in the reaction. Calculate the amount of product that can be formed from each reactant using stoichiometry. The reactant that produces the least amount of product is the limiting reactant.
Why is the theoretical yield of a reaction determined only by the amount of the limiting reactant?
The theoretical yield of a reaction is determined by the limiting reactant because this reactant is completely consumed in the reaction, and the amount of product that can be formed is limited by the amount of the limiting reactant available. Any excess of the other reactant does not contribute to the formation of additional product beyond what is possible with the limiting reactant.
What reactant gives the lowest yield by limiting the amount of product?
A reactant that gives the lowest yield by limiting the amount of product is called a limiting reactant. The limiting reactant will run out, so that only a limited amount of product can be made from the reactants.
For the following reactions identify the limiting reaction and excess reactant Give reasons for your choices A Wood burning in a campfire B sulfur in the air reacting with silver flatware?
A. In the wood burning reaction, oxygen is the limiting reactant because there is a finite amount present in the air compared to the potentially unlimited amount of wood. The wood is the excess reactant since it is in excess of what the limited amount of oxygen can react with. B. In the reaction between sulfur in the air and silver flatware, the limiting reactant would be the sulfur since it is present in a limited amount compared to the silver flatware. The silver flatware is the excess reactant as it is in excess of what the limited amount of sulfur can react with.
What is the reactant called that gets used up first?
The Limiting Reactant is the reactant that runs out first in a reaction.
Why is it necessary to determine if a reactant is a limited reagent in a reaction?
The amount of product formed will be limited by the amount of the limiting reagent.

How do you figure out the limited reagent?
To find the limiting reagent in a chemical reaction, you calculate the amount of product that each reactant can produce. The reactant that produces the least amount of product is the limiting reagent. You can then use this information to determine the amount of product that can be formed in the reaction.
What is the reactant called that gets used up first?
The Limiting Reactant is the reactant that runs out first in a reaction.
