Question

"90.0 g of FeCl₃ reacts with 52.0 g of H₂S to produce HCI and Fe₂S₃. What is

the limiting reactant? What is the mass of HCl produced? What mass of
excess reactant remains after the reaction?"

Answer 1

To find the limiting reactant between FeCl3 and H2S, we need the balanced chemical equation. With that information, the stoichiometric ratios can determine which reactant limits the amount of HCl produced and how much of the excess reactant remains.

Step-by-step explanation:

To determine the limiting reactant, the stoichiometric ratios from the balanced chemical equation must be considered. The balanced equation for the reaction between FeCl3 and H2S that produces HCl and Fe2S3 is not provided, but it is essential for calculating the limiting reactant. One needs to find the coefficients for each reactant and product in the balanced equation and then calculate moles of reactants from their given masses. Using the mole ratios from the balanced equation, one can compare which reactant is depleted first, thus limiting the amount of product formed.

Once the limiting reactant is identified, the theoretical yield of HCl can be calculated by using stoichiometry based on the amount of the limiting reactant. As for the excess reactant, its remaining mass can be found by calculating how much of it reacted with the limiting reactant and then subtracting that from the initial mass provided.

Without the balanced equation, we cannot calculate the exact mass of HCl produced or the mass of the excess reactant remaining after the reaction.
