2) Consider the following situation. A student has been asked to determine if an unknown sample is either dichloromethane (CH.Cle) or ethyl chloride (CHCI). She surmises that the two compounds have different percentages, by mass, of chlorine, so that an analysis of that percentage should afford the answer to her question. She then conducts the following reactions and collects the data as indicated below. (1) Determine whether the unknown was dichloromethane or ethyl chloride. You must show your work for full credit CO20) + H2O(g) + NaCl reaction #1: 0.420g of unknown + Na (s) + heat ---> dissolve resulting NaCl in 20.0mL of dilute nitric acid NaNO3(aq) + AGCI (s) reaction #2: NaCl(aq) + AgNO3(aq) 1.42g of silver chloride recovered
