Q. When solutions of silver nitrate and calcium chloride are mixed, silver chloride precipitates out of solution according to the equation. 2AgNO3(aq) + CaCl2(aq) → 2AgCl(s) + Ca(NO3)2(aq). What mass of silver chloride can be produced from 1.14 L of a 0.125 M solution of silver nitrate? Express your answer in grams. The reaction described in Part A required 3.18 L of calcium chloride. What is the concentration of this calcium chloride solution? Express your answer in units of molarity.

Q. Redox titration are used to determine the amounts of oxidizing and reducing agents in solution. For example, a solution of hydrogen peroxide, H2O2, can be titrated against a solution of potassium permanganate, KMnO4. The following equation represents the reaction: 2KMnO4(aq) + H2O2(aq) + 3H2SO4(aq) → 3O2(g) + 2MnSO4(aq) + K2SO4(aq) + 4H2O(l). A certain amount of hydrogen peroxide was dissolved in 100. mL of water and then titrated with 1.68 M KMnO4. How much H2O2 was dissolved if the titration required 16.8 mL of the KMnO4 solution? Express your answer numerically in grams.
