What's included:
- Plain text response
Organometallic chemsitry - Explain the fact that most complexes of Zn2+ are colorless.
Coordination chemistry: reactions and mechanisms - Which of the two complexes W(CO)6 or IrCl(PPh2)2(CO) should undergo the most labile exchange with 13CO. Explain.
Organometallic chemistry - The Pt-Rh catalyst in catalytic converters is dispersed on a ceramic substrate rather than as a thin foil. Why is this the case?
Working with half lives to determine the time required to reach a certain percentage of its initial concentration. - A first order reaction has a half-life of 157 seconds. How much time is required for the reactant to be reduced to 12.5% of its initial concentration?
Identifying ligands and their charges. - Identify the ligands and their charges in Co(en)2(CN)2+.
