Answer 1

Answer:

Fe3(CN)6

.......... Ferrous Hexacynaide.

Answer 2

The formula of $Fe^{2+}$ ion is bound with six cyanide ions is $K_{4}Fe(CN_{6})$.

Explanation:

A chemical formula is defined as the representation which tells the number of atoms of same or different elements chemically combined together.

For example, a compound $K_{4}Fe(CN_{6})$ is known as potassium ferrocyanide. In this compound, there are potassium, iron and cyanide atoms present.

Oxidation state of iron in this compound is calculated as follows.

               4 + x + (-6) = 0

                   x = +2

Here, the $Fe^{2+}$ ion is attached with six cyanide ions.
