Question #766de

1 Answer

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#
