Question

The term "3 FeCl2" in a balanced equation says A) that there are three iron(II) ions and two chloride ions bonded together. B) that there are three iron(II) ions and 6 chloride ions bonded together. C) that there are three formula units, each consisting of two chloride ions bonded to an iron(II) ion. D) that there are three particles, each consisting of three iron atoms and 6 chlorine atoms.

Answer 1

Answer : The correct option is C.

Explanation :

In $3FeCl_2$, 3 $Fe^{2+}$ ions and 6 $Cl^-$ ions are present. $3FeCl_2$ is formed when two $Cl^-$ ions bonded to an $Fe^{2+}$ ions.

Thus, the term $3FeCl_2$ in a balanced chemical equation says that there are three formula units, each consisting of two chloride ions bonded to an iron(II) ion.

Answer 2

The answer is C) that there are three formula units, each consisting of two chloride ions bonded to an iron(II) ion.
