Linc is extracted from $\angle n S$ by the (a) Roasting of $\angle \mathrm{nS}$ followed by aluminium reduction at $1200^{\circ} \mathrm{C}$ in a muffle furnace. (b) Roasring of $7 n 5$ followcd hy carhon monoxide rcrlucrion ar $1200^{\circ} \mathrm{C}$ in a smclrer. (c) Calcinarion of $7 \mathrm{nS}$ followes by hyedrogcn rctucrion at $400^{\circ} \mathrm{C}$ (d) Calcinarion of $7 n \mathrm{~S}$ followed by carbon dioxide reduction.
The carbon-based reduction method is NOT used for the extraction of [Adv. 2013] (a) Tin from $\mathrm{SnO}_{2}$ (b) Iron from $\mathrm{Fe}_{2} \mathrm{O}_{3}$ (c) Aluminium from $\mathrm{Al}_{2} \mathrm{O}_{3}$ (d) Magnesium from $\mathrm{MgCO}_{3} \cdot \mathrm{CaCO}_{3}$

The Hall process is an important method by which pure aluminum is prepared from its oxide (alumina, $\mathrm{Al}_{2} \mathrm{O}_{3} )$ by indirect reaction with graphite (carbon). Balance the following equation, which is a simplified representation of this process. $$\mathrm{Al}_{2} \mathrm{O}_{3}(s)+\mathrm{C}(s) \rightarrow \mathrm{Al}(s)+\mathrm{CO}_{2}(g)$$
