CHAPTER 4 MAKE UP HOMEWORK 1. Lead ions can be precipitated from solution with KCl according to the following reaction: Pb 2+ (aq) + 2 KCl (aq) PbCl 2 (s) + 2 K + (aq) When 28.5 g KCl is added to a solution containing 25.7 g Pb 2+ , a PbCl 2 precipitate forms. The precipitate is filtered and dried and found to have a mass of 29.4 g. Determine the limiting reactant, theoretical yield of PbCl 2 , and the percent yield for the reaction. 2. Calculate the molarity of each of the following solutions. a. 0.11 mol LiNO 3 in 5.2 L of solution b. 61.3 g C 2 H 6 O in 2.44 L of solution c. 15.2 mg KI in 102 mL of solution 3. Write the balanced complete ionic and net ionic equations for each of the following reaction. a. HCl (aq) + LiOH (aq) H 2 O (l) + LiCl (aq) b. MgS (aq) + CuCl 2 (aq) CuS (aq) + MgCl 2 (aq) c. NaOH (aq) + HNO 3 (aq) H 2 O (l) + NaNO 3 (aq) d. Na 3 PO 4 (aq) + NiCl 2 (aq) Ni 3 (PO 4 ) 2 (s) + NaCl (aq) 4. Complete and balance each of the following equations for acid-base reactions:
