(a)[1]
Suggest a physical property that titanium has.
(b(i))[1]
Titanium(IV) chloride, TiCl$_4$, is a colourless liquid and boils at a low temperature. Suggest the structure and bonding present in TiCl$_4$.
(b(ii))[2]
When titanium(IV) chloride reacts with water, hydrochloric acid and a precipitate of titanium(IV) oxide are formed. Write the equation for this reaction, including state symbols.
(c)[3]
Titanium is extracted by reducing TiCl$_4$ with magnesium. $\text{TiCl}_4 + \text{2Mg} \rightarrow \text{2MgCl}_2 + \text{Ti}$ Calculate the mass of titanium produced from 1000 g of TiCl$_4$. The reaction gives a 90% percentage yield. Give your answer to two significant figures. [The relative atomic mass of titanium, Ti, is 48.]
