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.


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.


What causes chemical bond to break during a reaction?

Energy is added to break bonds, so there is your simple answer. But some bonus info for you:Bond energy is the amount of energy it will take to break a bond (ironic, because it sounds like the amount of energy it will take to MAKE a bond, even though it's the opposite).Energy is released when bonds form, and the same amount of energy is released when the bond is broken.


Does the total number of atoms stay the same during a chemical reaction?

Indeed by the Law of Conservation of Mass, mass cannot be lost or gained through a reaction. Similarly, atoms cannot be lost, gained or somehow transformed themselves-only rearranged into different compounds. This means there are still going to be the same amount of Hydrogen atoms after a reaction as there were before.


A chemist interested in the efficiency of a chemical reaction would calculate the?

The chemist would calculate the reaction yield, which is the amount of product formed compared to the theoretical maximum amount that could be obtained. This provides a measure of how efficient the reaction is at converting reactants into products. Additionally, the chemist may also calculate reaction rate to determine how quickly the reaction proceeds.

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"


What happens to the amount of energy during a chemical reaction?

Do it yourself idiot.


Does the amount of energy change during a chemical reaction?

What is constant during a chemical reaction?

Amount of energy because it can not be created or destroyed.


Why don't solids and liquids affect equilibrium in a chemical reaction?

Solids and liquids do not affect equilibrium in a chemical reaction because their concentrations remain constant during the reaction. This is because the amount of solid or liquid present does not change as the reaction progresses, so they do not impact the equilibrium concentrations of the reactants and products. Only the concentrations of gases and aqueous solutions can affect the equilibrium of a chemical reaction.


When the limiting reactant in a chemical reaction is completely used the?

When the limiting reactant in a chemical reaction is completely used, the reaction stops because there are no more reactants available to continue producing products. At this point, any excess reactants or products may still be present in the reaction mixture. The amount of product formed will be determined by the amount of limiting reactant that was originally present.


Did you recover the same amount of copper you started with?

Yes, the amount of copper recovered through a chemical reaction or a purification process typically matches the initial amount that was present before the reaction or process began.


What are the salient features of catalyst?

A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.


What is the relationship between the heat of reaction and a chemical reaction?

The heat of reaction is the amount of heat energy released or absorbed during a chemical reaction. It is a measure of the reaction's energy change. The relationship between the heat of reaction and a chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat). This information helps us understand the energy changes that occur during the reaction.


Does the total amount of mass during a chemical reaction increase?

The total mass of the compounds remain constant.
