To determine the limiting reagent, you must first determine moles of each reactant, and then look at the mole ratios among the reactants to see which one is in the least supply. That one will be the limiting reagent.

What is the limiting reagent when sodium hydroxide and copper chloride react?
2 Na OH + CuCl2
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.

Iron II sulfide is produced when iron is heated with sulfur what is the therotical yield of FeS if 25.0 g Fe is heated with 32.0 g S?
Fe + S = FeS ---- 1) The first thing you need to determine is whether Fe or S is the limiting reagent. To do this you need the atomic mass of both Fe and S, which can be found on the periodic table. a) Fe = 56 and S = 32 Next, divide the given mass of the substance by the atomic mass. a) Fe = (25.0 / 56) = 0.4464 (moles of Fe) S = (32.0 / 32) = 1.0 (moles of S) Next, divide the number of moles of substance by the coefficient in front of the element (see the above chemical equation) a) Fe = (0.4464/1) = 0.4464 S = (1/1) = 1 Now you can see that the final number for Fe is smaller than the final number for S. This means that Fe is the limiting reagent and S is in excess. ---- 2) Now you can do a simple stoichiometry problem using Fe and converting to FeS. Always use the limiting reagent in the stoichiometry problem. Note: FeS = 88 (25) (1) (88) = 2200 = 25 (56) (1) 88 ---- The theoretical yield of FeS is 25g.
What happens during a chemical reaction?
Electrons in atoms and molecules, etcare rearranged. This results in chemical bonds forming or being broken and thus new substances being formed.Electronsare rearranged.
What determine the effect of a limiting reagent on the mass of a product?
the amount of limiting reagent
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.
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 limiting reagent in 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 limiting reagent in a reaction?
The amount of product formed will be limited by the amount of the limiting reagent.
Which ions is the limiting reagent and which is the reagent in excess when barium sulphate is made?
When barium sulfate is made, the limiting reagent is the one that is completely consumed in the reaction and determines the amount of product formed. In this case, if barium ions (Ba2+) and sulfate ions (SO42−) are the reactants, the limiting reagent would be the one that is present in lower molar quantity. The one in excess would be the one that is present in higher molar quantity. Without the quantities of each ion provided, it is difficult to determine which is the limiting reagent and which is in excess.

Which reagent is the limiting reagent in a reaction?
The one that runs out first in a reaction - is thoroughly accurate. There are quite a few other limiting reagents in limiting reactions - as well.
Does the excess reagent determine the amount of a product?
The limiting reagent is the determinant because you can only make as much as the smallest amount can provide to react with
