May 4, 2024 · Identify the limiting reactant (limiting reagent) in a given chemical reaction. Calculate how much product will be produced from the limiting reactant. Calculate how much reactant(s) remains when the reaction is complete.
1. What is a limiting reactant? 2. What is an excess reactant? 3. How do you determine the limiting and excess reactant for a reaction? 4. Answer the following questions using the balanced reaction below. CuCl2 + 2 NaNO3 Cu(NO3)2 + 2 NaCl. a.
To determine the amounts of product (either grams or moles), you must start with the limiting reagent. Use the amount that you have, not the amount you need. To determine the grams of excess reagent, subtract the amount you need from the amount that you have, then using the molar mass, convert the moles left to grams.
Jul 12, 2023 · Determine which reactant is limiting by dividing the number of moles of each reactant by its stoichiometric coefficient in the balanced chemical equation. Use mole ratios to calculate the number of moles of product that can be formed from the limiting reactant.
