I have 2 questions when I was doing homework...
1. What metal ions have ammine complex -- other than Ni, Ag, Zn, Cd, Co, Cu, Hg? (for exmple, does Pb or Fe3+ have ammine complex?) Why they differ in the number of NH3?
2. From the 4 types of chemical reactions -- redox, precipitation, acid-base, complex ion formation, which one is proper for the following reaction
LiHCO3(s)+heat-->Li2CO3(s)+CO2(g)+H2O(g)
Please give me some help. Thx!
