This question is about extraction and displacement reactions.
The reduction of titanium(IV) chloride with magnesium has a high activation energy.
What is meant by 'activation energy'?
A reaction mixture contains 0.36 kg0.36\text{ kg}0.36 kg of magnesium and 1.52 kg1.52\text{ kg}1.52 kg of titanium(IV) chloride.
The equation for the reaction is:
TiCl4+2Mg→Ti+2MgCl2 \text{TiCl}_4 + 2\text{Mg} \rightarrow \text{Ti} + 2\text{MgCl}_2 TiCl4+2Mg→Ti+2MgCl2Show that magnesium is the limiting reactant.
Relative atomic masses (ArA_rAr): Mg=24\text{Mg} = 24Mg=24, Cl=35.5\text{Cl} = 35.5Cl=35.5, Ti=48\text{Ti} = 48Ti=48
Magnesium displaces copper from copper(II) sulfate solution.
Complete the ionic equation for the reaction. You should include state symbols.
Mg(s)+Cu2+(aq)→________+________ \text{Mg(s)} + \text{Cu}^{2+}\text{(aq)} \rightarrow \text{\_\_\_\_\_\_\_\_} + \text{\_\_\_\_\_\_\_\_} Mg(s)+Cu2+(aq)→________+________Explain why the reaction between magnesium atoms and copper(II) ions is both oxidation and reduction.
