please help i cant figure them out
Consider the insoluble compound nickel(II) carbonate, NiCO3. The nickel ion also forms a complex with cyanide ions. Write a net ionic equation to show why the solubility of NiCO3(s) increases in the presence of cyanide and calculate the equilibrium constant for this reaction. Solubility product constant data is found in the Chemistry References. For Ni(CN)4?: K = 2.0 1031. Use the pull-down boxes to specify states such as (aq) or (s). A solution...
