Titanium is a high-strength transition metal extracted from its ore via the Kroll process. In the final stage of this process, titanium(IV) chloride, TiCl4\text{TiCl}_4TiCl4, is reduced by magnesium metal at high temperatures:
TiCl4+2Mg→Ti+2MgCl2 \text{TiCl}_4 + 2\text{Mg} \rightarrow \text{Ti} + 2\text{MgCl}_2 TiCl4+2Mg→Ti+2MgCl2What is the percentage atom economy for the production of titanium in this reaction?
Use the following relative atomic masses (ArA_rAr): Ti=47.9\text{Ti} = 47.9Ti=47.9, Cl=35.5\text{Cl} = 35.5Cl=35.5, Mg=24.3\text{Mg} = 24.3Mg=24.3.
