How To Find The Amount of Excess Reactant That Is Left Over

What is excess reactant?

The excess reactant is the reactant in a chemical reaction with a greater amount than necessary to react completely with the limiting reactant. It is the reactant(s) that remain after a chemical reaction has reached equilibrium.

How many moles of the excess reactant remain unreacted?

If there is an excess number of \(\ce{Cl2}\) molecules, they will remain unreacted. We can also state that 6 moles of sodium will require 3 moles of \(\ce{Cl2}\) gas. If there are more than 3 moles of \(\ce{Cl2}\) gas, some will remain as an excess reagent, and the sodium is a limiting reagent.

How do you find theoretical yield?

How to Calculate Theoretical Yields

  • Determine the number of moles of each reactant.
  • Multiply the molecular weight by the number of moles in the equation.
  • Calculate the theoretical mole yield by using the chemical equation.
  • Multiply the number of moles of the product by the molecular weight of the product to determine the theoretical yield.

How do you solve stoichiometry?

There are four steps in solving a stoichiometry problem:

  1. Write the balanced chemical equation.
  2. Convert the units of the given substance (A) to moles.
  3. Use the mole ratio to calculate the moles of wanted substance (B).
  4. Convert moles of the wanted substance to the desired units.
