- the limiting reactant is how much of a compound or solution you need to make an experiment possible. the excess reactant is the amount left over from the other compound or solution used (the other reactant that is used)

Does a decomposition reaction decompose to a limiting reactant and a theoretical reactant?
there is a difference between decompositon reaction and to decompose the reaction mixture in (for example ice/HCl) n'mixture which for lmiting the excess reagents
How limiting reactant control a reaction?
Using an excess of another reactant limits a reactant.
The substance not completely used up in a chemical reaction is known as the?
a product
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.
Why does the amount of product formed is directly proportional to the amount of limiting reactant used?
because the limiting reactant is not in excess so it's all used up . as the limiting reactant is used up the reaction stops so no more product can be made.
Why is it necessary to identify the limiting reactant when you want to know how much product will form in a chemical reaction?
The limiting reactant tells you how much of each reactant is formed. If you use the excess material a false answer for the calculated products will come out.
What is the limiting reactant reagent and what is excess reagent in recrystallization?
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.
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.
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 is a limiting agent?
In many chemical reactions, there are two reactants. In nearly every case, one of those two reactants "runs out" first, and at that point, the chemical reaction stops, because in order for it to happen, both reactants must be present to react with each other. As soon as the one reactant runs out, the reaction is over, and you have product(s) and one left over reactant. The reactant that runs out first is the limiting reactant. The leftovers are the excess reactant.
What would happen if the reactants were removed from the equation?
The reaction stops. If you have a reactant that runs out, it's called the limiting reactant. Even if you have plenty of the other reactant (called the excess reactant), your reaction requires both, so once it runs out you will no longer be producing any product.
How many liters of hydrogen gas are formed from 6.0 g of HCl and 5.0 g of mg?
Assuming we are at standard temperature and pressure (STP), the answer is approximately 1.85L of hydrogen gas. The HCl is the limiting reactant and the Mg is the excess reactant.
