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.

Explanation:

In the chemical formula $FeCl_2$, one iron(II) ion ($Fe^{2 + }$) is bonded to two chloride ions ($Cl^-$). The coefficient 3 in front of $FeCl_2$ indicates that there are three formula - units of $FeCl_2$. Each formula - unit consists of one iron(II) ion and two chloride ions.

Answer:

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