Practice Problems: Limiting Reagents. Take the reaction: NH 3 + O 2 NO + H 2 O. In an experiment, 3.25 g of NH 3 are allowed to react with 3.50 g of O 2. Hint. a. Which reactant is the limiting reagent? b. How many grams of NO are formed? c. How much of the excess reactant remains after the reaction? Oxygen is the limiting reagent. Solution path #2: 1) Calculate moles: sucrose ⇒ 0.0292146 mol oxygen ⇒ 0.3125 mol. 2) Divide by coefficients of balanced equation: sucrose ⇒ 0.0292146 mol / 1 mol = 0.0292146 oxygen ⇒ 0.3125 mol / 12 mol = 0.02604 Oxygen is the lower value. It is the limiting reagent. Practice some actual yield and percentage problems below. 1.

  • 1970 camaro specsTnt onlineLimiting Reagents A Limiting Reagent is the reactant that is completely used up in a reaction. This reagent is the one that determines the amount of product formed. Limiting reagent calculations are performed in the same manner as the stoichiometric equations on Worksheet #11. However, with a limiting 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. It limits the amount of the product that can be formed. Chemical reactions with stoichiometric amounts of reactants have no limiting or excess reagents.
