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

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

$M g + F e C {l}_{3} \to M g C {l}_{2} + F e$

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

$3 M g + 2 F e C {l}_{3} \to 3 M g C {l}_{2} + 2 F e$
