(a) A compound with formula RuCl3 . 5 H2O is dissolved inwater, forming a solution that is approximately the samecolor as the solid. Immediately after forming the solution,the addition of excess AgNO3(aq) forms 2 mol of solid AgClper mole of complex. Write the formula for the compound,showing which ligands are likely to be present in the coordinationsphere. (b) After a solution of RuCl3 . 5 H2O hasstood for about a year, addition of AgNO3(aq) precipitates 3mol of AgCl per mole of complex. What has happened inthe ensuing time?

Reacting Cr(CO)6 with a 2 molar equivalent of PPh; produces a disubstituted chromium complex [Cr(CO)4(PPH3)2] and two molecules of CO. This complex can exist as either trans-[Cr(CO)4(PPh;)2] or cis-[Cr(CO)4(PPH3)2]. The infrared spectrum for this complex has 4 CrC-O vibrations in the metal carbonyl region. Determine which isomer has formed in this reaction.
The K, for (Cu(en),1* is much larger than the one for (Cu(NH,),]2+. This difference is primarily an entropy effect. Explain why and calculate the difference between the AS values at 298 K for the complete dissociation of the two complex ions. (Hint: The value of AH is about the same for both systems.)
