    Silicon tetrachloride is SiCl4 and Magnesium is Mg (Reactants)
    Silicon is Si and Magnesium Chloride is MgCl2 - Magnesium is a group 2 metal so forms a 2+ ion and requires 2 chloride ions (Products)

    Therefore the first step of the equation gives: SiCl4 + Mg -> MgCl2 + Si
    Then it needs balancing to give an equal number of each atom on both sides: SiCl4 + 2Mg -> 2MgCl2 + Si
