If the question asks how much is something produced with the following equation, then you need to use the limiting reagant to answer the question because you only have a certain amount of reactants to make the products.
For example: to make a s'more, it requires 2 crackers, 1 piece of chocolate, and 1 marshmallows. But what happens if you have 4 crackers, 2 pieces of chocolate, and 1 marshmallow? How many s'mores can you make?
Answer: Only 1 because the marshmallow is limiting. You need another marshmallow to make a 2nd s'more, but you don't have enough.
I hope this makes sense...

How do you determine the limiting agent and excess?
The limiting agent in a chemical reaction is the reactant that is completely consumed first, stopping the reaction. To determine the limiting agent, calculate the amount of product each reactant can produce and identify the one that produces the least amount of product. The other reactant is then in excess.
When 15.0 g and NaCIO3 and 20.0 g Cr2O3 react which will limit the reaction?
First, calculate the moles of each reactant. Next, determine which reactant is the limiting reactant by comparing the moles of each reactant to the stoichiometry of the balanced chemical equation. The reactant that produces the least amount of product based on stoichiometry is the limiting reactant.
What is the first step in determining a limiting reactant?
The first step in determining a limiting reactant is to write a balanced chemical equation for the reaction. This will allow you to compare the stoichiometry of the reactants and products and determine which reactant limits the amount of product that can be formed.
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 happens to a chemical reaction when the limiting reactant is completely used up?
Limiting reactant is the one that limits the rate of the reaction. It is always supplied in adequate amount so that there is enough for the reaction to carry out to obtain the desired products. under ideal cases, When the reaction reaches completion there will be no limiting reactant.
Why is necessary to determine if a reactant is limiting reagent in a reaction?
The amountof product form will be limited by the amount of the limiting reagent
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.
Which reactant in the reaction of sodium carbonate and calcium chloride dihydrate is the limiting reactant if 1.00 gram of each reagent is used?
To determine the limiting reactant, calculate the moles of each reactant using their molar masses. Then, use the stoichiometry of the reaction to determine which reactant will be consumed first. Whichever reactant produces the lesser amount of product will be the limiting reactant.
How do you determine the limiting agent and excess?
The limiting agent in a chemical reaction is the reactant that is completely consumed first, stopping the reaction. To determine the limiting agent, calculate the amount of product each reactant can produce and identify the one that produces the least amount of product. The other reactant is then in excess.
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 identify the limiting reactant when you want to know how much product will form in a chemical reaction?
Identifying the limiting reactant allows you to determine which reactant will be completely consumed first, thereby limiting the amount of product that can be formed. This information is crucial for calculating the maximum amount of product that can be produced in a reaction, ensuring efficient use of reactants.
After a chemical reaction starts when will a chemical reaction end?
A chemical reaction will end when the reactants are completely consumed and the products have reached equilibrium. This can vary in time depending on the reaction rate and conditions such as temperature and pressure.
What would be the limiting reagent in the reaction show below 2H plus O2 - 2H2O?
In the reaction 2H2 + O2 -> 2H2O, the limiting reagent is the reactant that will be completely consumed first. To determine the limiting reagent, compare the moles of each reactant to the stoichiometry of the reaction. Whichever reactant produces the least amount of product is the limiting reagent.
Why is it necessary to determine if a reactant is is a limiting reagent in a reaction?
Identifying the limiting reagent is important because it determines the maximum amount of product that can be formed in a reaction. If the reactant ratio is not optimal, some reactants may be left over, leading to inefficiency and wastage. Therefore, understanding the limiting reagent helps to optimize reactions and conserve resources.
What is the reactant that runs first out in a reaction called?
The Limiting Reactant is the reactant that runs out first in a reaction.
What is the definetions of limiting reactant in chemistery?
The limiting reactant in chemistry is the reactant that is completely consumed in a chemical reaction, limiting the amount of product that can be formed. It determines the theoretical maximum amount of product that can be produced in a reaction. The amount of product formed is dictated by the amount of the limiting reactant present.
Why is it necessary to determine if a reactant is limiting reagent in reaction?
Identifying the limiting reagent is crucial to ensure maximum product yield in a reaction. It helps in calculating the exact amount of each reactant needed and prevents wasting any excess reactants. Knowing the limiting reagent also allows for accurate predictions of product quantities.
