Consider the insoluble compound iron(II) carbonate , FeCO3 . The iron(II) ion also forms a complex with cyanide ions . Write a balanced net ionic equation to show why the solubility of FeCO3 (s) increases in the presence of cyanide ions and calculate the equilibrium constant for this reaction. For Fe(CN)64- , Kf = 7.7×1036 . Use the pull-down boxes to specify states such as (aq) or (s).

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
