Question

1. Write a complete, balanced chemical equation, with state symbols, for the reaction of aluminum with an aqueous solution of hydroiodic acid.

2.This question refers to the reaction described in problem 1. Identify the limiting reactant given 0.30 mol of aluminum and 1,200 mL of 0.30 M hydroiodic acid solution. Show the steps of the least product method. Write an outline of your major steps before “plunging” into the answer.

3. A solution of ammonium chloride reacts with a solution of lead(II) nitrate. a) What is the theoretical yield, in g, of solid product if you began with 2.8 L of 0.40 M of ammonium chloride and 1.7 L of 0.31 M of lead(II) nitrate? b) What is the % yield if, at the end of the experiment, you obtained 100.23 g of the solid product. Write an outline of your steps before “plunging” into the answer.

4. A 23.5 mL sample of NaOH is neutralized with H2SO4. What is the molarity concentration of the NaOH if 11.0 mL of 0.180 M H2SO4 are required to completely neutralize the base?
