How does the maximum yield of products for a reaction depend on the limiting reactant?
The best way to answer this question is with an example. Using Calcium oxide reacting with hydrochloric acid, the reaction formula is:
CaO + 2HCl ----->CaCl2 + H2O
The molecular weight for Calcium Oxide is 56, for Hydrochloric acid is 26.5 and for calcium chloride 110. If you start with only 56g of Calcium oxide but say 10000g of hydrochloric acid, the maximum yield of the product calcium chloride can only ever be 110g. It does not matter how much hydrochloric acid is added. The limiting reactant in this example is the calcium oxide.

Why is the term limiting used to describe the limiting reactant?
The term "limiting" is used to describe the reactant that is completely consumed in a chemical reaction, thus limiting the amount of product that can be formed. It determines the maximum amount of product that can be produced based on its stoichiometry and quantity.
The substance whose mass is used to calculate the theoretical yields of the products is known as what?
If I recall my chemistry class from 10 years ago correctly, that's the limiting reagent.
When calculating the amount of product that will form during a reaction a value for the ......is obtained?
When calculating the amount of product that will form during a reaction, a value for the limiting reactant is obtained. The limiting reactant is the substance that is completely consumed first in a chemical reaction, thereby determining the maximum amount of product that can be formed. By using stoichiometry based on the balanced chemical equation, one can convert the moles of the limiting reactant into moles of the desired product.
What is the maximum mass of S8 that can be produced by combining 75 grams of each reactant?
The molar mass of S8 is 256 g/mol. To calculate the maximum mass of S8 that can be produced, first determine the limiting reactant by converting the masses of the reactants to moles. Then, use the stoichiometry of the reaction to find the mass of S8 produced from the limiting reactant.
What is the limiting reagent in a reaction?
The limiting reagent in a reaction is the reactant that runs out first. For example, if you are reacting 10 moles of HCl and 5 moles of NaOH, you will get 5 moles of H20, 5 moles of NaCl, and 5 moles of HCl, because the remaining HCl had nothing to react with. Therefore, the NaOH is the limiting reagent.
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"
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.
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.
Why does the amount of product formed is directly proportional to the amount of limiting reactant used?
The amount of product formed is directly proportional to the amount of limiting reactant used because the limiting reactant determines the maximum amount of product that can be produced in a chemical reaction. Any excess reactant beyond the limiting reactant will not contribute to the formation of additional product. Thus, the amount of product formed is dictated by the amount of limiting reactant available.
Why is limiting reactants important in stoichiometry?
Limiting reactants are the reactants that are used up first. And once they are used up, they stop, or limit, the reaction. So the amount of product that can be produced depends on the limiting reactant. The other reactant, the one in excess, would predict a larger amount of product. But once we produce the amount of product predicted by the limiting reactant. The limiting reactant is used up and the reaction stops.
Why is the term limiting used to describe the limiting reactant?

What is the limiting reactant in Mg plus HCl?
In the reaction between magnesium (Mg) and hydrochloric acid (HCl), the limiting reactant is the reactant that is consumed first, which determines the maximum amount of product that can be formed. To determine the limiting reactant, you would need to compare the moles of magnesium and hydrochloric acid to see which one is present in the lowest stoichiometric amount.

How does a limiting reagent affect how much product is formed?
The amount of product will be limited by the number of moles of the limitin... 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.
