1. (20 points) Sodium Carbonate (Na2CO3) is produced by the Le Blanc Process using the following net reactions: NaCl + H,SO, +C+CaCO, → Na,CO, + CaS+HCI+CO, Staring with one ton of each reactant except for coal (C) which is available in unlimited amounts, and if 1100 pounds of sodium carbonate was obtained, determine the following: a. the limiting and excess reactants b. percent excess reactant present c. degree of completion (percent) of the reaction d. percent conversion of the excess reactants e. yield in kg of desired product per kg of limiting reactant consumed f. extent of reaction
