Fecl2 express your answers as ions separated by a comma.

In this item, it is assume that we are to express the dissociation of the formula unit given to be FeCl₂ into its ionic components. 

As seen in the chemical formula, the unit is composed of iron (Fe) and chlorine (Cl). The dissociation is written as follows;

     FeCl₂ --> Fe²⁺ + Cl⁻

This equation is balanced by multiplying the appropriate component with a number that would equate the number of atoms in both sides of the equation.

     FeCl₂ --> Fe²⁺ + 2Cl⁻
