Question

Which of the following chemical reactions represents Hall-Heroult Process?

Select the correct option:

$\mathrm{Cr}_2 \mathrm{O}_3+2 \mathrm{Al} \rightarrow \mathrm{Al}_2 \mathrm{O}_3+2 \mathrm{Cr}$

$2 \mathrm{Al}_2 \mathrm{O}_3+3 \mathrm{C} \rightarrow 4 \mathrm{Al}+3 \mathrm{CO}_2$

$\mathrm{FeO}+\mathrm{CO} \rightarrow \mathrm{Fe}+\mathrm{CO}_2$

$2\left[\mathrm{Au}(\mathrm{CN})_2\right]_{3 a 1}+\mathrm{Zn}(\mathrm{s}) \rightarrow 2 \mathrm{Au}(\mathrm{s})+\left[\mathrm{Zn}(\mathrm{CN})_4\right]^{2-}$

✓ Correct! Well done.
