9. Which is more stable: Ni(NH3)2+ or Ni(en)37+? Explain your reasoning.
Which complex is more stable to acid, [Ni(en)3](BF4)2 or [Ni(macrocycle)](BF4)2? Suggest a reason.
4. Which compound is more stable? Explain your reasoning.
Arrange these complexes from most stable to least stable. [Ni(en)3]2+ [Ni(EDTA)12 [Ni(en)3]2+ [Ni(EDTA)12
1. [Ni(H20)] + 6NH3 = [Ni(NH3);]+ 6H20 K= 2. [Ni(H2O).] + 3en = [Ni(en)]2+ + 6H20 K= 3. [Ni(H2O).)** + 2dien = [Ni(dien)]2+ + 6H20 ке
6. [Ni(en)]2+ + 6NH3 = [Ni(NH3).]2+ + 3en Show calculation for this and all following K's! K = 7. [Ni(dien) P* + 6NH = [Ni(NH3)4]* + 2dien KE

2. Which would you expect to be more sol Explain your reasoning. be more soluble in water, strontium thiosultado ntium thiosulfate or calcium thiosulfate? 3. Both chlorine and bromine can act as oxidizing agents. When KCl and Br2 are combined in the presence of methylene chloride, the color of the methylene chloride layer after thorough mixing is the color of bromine. Which is the stronger oxidizing agent, bromine or chlorine? Explain your reasoning.
2. Consider the following substitution reactions: Ni(en)2Cl2 2 H20 [Ni(OH2)2(en)2] Cl2 Ni(deen)2Cl2 +2 H20INi(deen)2(0H:2}2] Cl2 where deen N, N-diethylenediamine (CH3CH2)2NCH2CH2N H2 Identify which of the two you would expect to have a faster rate and clearly explain your logic.
