7. Answer the following question about this stoichiometry problem. Aluminum metal reacts with aqueous nickel(II) sulfate to produce aqueous aluminum sulfate and nickel as a precipitate. In this reaction, 75 grams of aluminum were combined with 330 grams of nickel(II) sulfate to produce 208 grams of aluminum sulfate. Find: the limiting reactant, theoretical yield, and percentage yield Plan: Next use mass-mole and mole-mole conversions of the two reactants to find the limiting reactant. Then use a mass-mole, mole-mole, and mole-mass conversion to determine the theoretical yield. Last, calculate the percentage yield. What is the theoretical yield?
