Convert the chemical names into chemical formulas. Place them based on the chemical equation.

Magnesium + iron(lll) chloride $\to$ $->$ Magnesium(ll)chloride + iron

$M g + F e C l_{3} \to M g C l_{2} + F e$ $Mg + FeCl_3 -> MgCl_2 + Fe$

Then balance the chemical equation .meaning there are equal numbers of atoms on each side.

$3 M g + 2 F e C l_{3} \to 3 M g C l_{2} + 2 F e$ $3Mg + 2FeCl_3 -> 3MgCl_2 + 2Fe$
