Solve the all parts of given problem:
Problem: Aluminum sulfate is used in water treatment and in many chemical processes. It can be by reacting crushed bauxite (aluminum ore) with 77.7 weight percent sulfuric acid. The bauxite ore contains 55.4 weight percent aluminum oxide,, the reminder being impurities. To produce crude aluminum sulfate containing 2000 lb of sulfuric acid solution (77.7% acid) are.
Part A: Identify the excess reactant?
Part B: What percentage of excess reactant was used?
Part C: What was the degree of completion of the reaction?
Part D: Calculate the conversion of the limiting reactant?
I know the correct answer for above problem but explain how to get this answer! Thanks.
