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).

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
