Consider the precipitation reaction of Lead(II) nitrate in aqueous solution with that of potassium iodide in solution producing solid Lead(II) iodide and aqueous potassium nitrate.   A. (5 points) Write the balanced molecular equation for the reaction.   B. (5 points) Identify the spectator ions and write the net ionic equation.   C. (15 points) Starting with 1 L of 0.100 M Lead(II) nitrate and 1 L of 0.100 M of potassium iodide solution, what is the limiting reagent and theoretical yield (in grams) of Lead(II) iodide for the reaction?   D. (5 points) If we are able to isolate 20.00 g of Lead(II) iodide what is the percent yield for the reaction?
