The Limiting Reactant is the smaller number once you compare the two reactants with one product. The product that you are comparing them both with must be the same. The Excess Reactant is the larger number, or the amount left over in the chemical reaction.

Can the mass of the limiting reagent be higher than the mass of the excess reagent?

it may be , the limiting reactant is that which is totally consumed during the reaction but its amount must be less than required amount with respect to excess reactant for example, H2SO4 + 2NaOH = Na2SO4 + 2H2O in this reaction suppose acid is 95 g and base is 85 g but acid with higher amount is the limiting reactant and base is in excess. Essentially, it's possible whenever the molecular weight of the limiting reagent is higher than the molecular weights of the other reagents.


What determines the effect of a limiting reagent on the mass of product?

the amount of limiting reagent


3.5 moles of TiCl4 reacts with 4.5 moles of O2 limiting and excess reactants are?

TiCl4 is limiting reagent, O2 is in excess


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.


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 a excess reagent?

In most reactions there are two types of reactant. One of them is completely consumed and the other is only partially consumed. The reactant that is only partially consumed is the excess reactant.

Does the excess reagent determine the amount of a product?

No, the excess reagent does not determine the amount of product formed in a chemical reaction. The amount of product is determined by the limiting reagent, which is the reactant that is completely consumed first. The excess reagent will remain in excess after the reaction is complete.


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 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.


What is the limiting reagent when sodium hydroxide and copper chloride react?

The limiting reagent is the reactant that is completely consumed first in a chemical reaction. To determine the limiting reagent in the reaction between sodium hydroxide and copper chloride, you would need to compare the moles of each reactant present and see which one is in excess and which one is limiting.

How do manufacturers decide which reactant to use in excess in a chemical reaction?

Manufacturers decide which reactant to use in excess based on factors such as cost, availability, and desired product yield. The reactant that is cheaper or more readily available is often used in excess to drive the reaction to completion and maximize product yield. Additionally, excess of one reactant can help to avoid side reactions or ensure complete conversion of the limiting reactant.


What steps are needed to determine the amount of excess reagent in a chemical reaction?

To determine the amount of excess reagent in a chemical reaction, first calculate theoretical values for your reaction to get an estimation of how much of your excess reagent will be left once the limiting reagent is used. Then run the actual experiment and measure!


3.5 moles of TiCl4 reacts with 4.5 moles of O2 limiting and excess reactants are?

TiCl4 is limiting reagent, O2 is in excess


What is the limiting reagent when 3.1 moles of so2 react with 2.7 moles of o2?

To determine the limiting reagent, first write the balanced chemical equation for the reaction. Then, calculate the moles of product that can be formed from each reactant. The reactant that produces the least amount of product is the limiting reagent.


Can there be a limiting reagent if only one reagent is present?

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.
