1.Suppose that you are going to collect H2 gas produced from the reaction of an acid with a metal such as zinc. This reaction gives off heat, so the tem perature of the solution will increase as the reaction proceeds. You need to know the partial pressure of the H2 you generate as precisely as possible What will you need to account for in your calculation? What things would you need to measure to make accurate calculations? What information would you need to look up?

2.Three acid samples are prepared for titration by 0.066040 M NaOH. Sample 1 is prepared by dissolving 0.015 mol of HCl in 50 mL of water. Sample 2 is prepared by dissolving 0.015 mol of HCl in 60 mL of water. Sample 3 is prepared by dissolving 0.015 mol of HCl in 40 mL of water. Rank the concentratio n of the three solutions, from highest to lowest. When the titration is performed, which sample, if any, will require the largest volume of 0.066040 M NaOH for the neutralization? Explain your answer.

3.What volume of 12.4 M HCl is needed to make 250 mL of 7.7040 M HCl
