Question #766de

Answer 1

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

Magnesium + iron(lll) chloride `->` Magnesium(ll)chloride + iron

`Mg + FeCl_3 -> MgCl_2 + Fe`

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

`3Mg + 2FeCl_3 -> 3MgCl_2 + 2Fe`
