Answer 2

A) Silicon is obtained by reducing silica with coke.

SiO  2 +C→Si+2CO

B) when silicon is heated with coke in the furnace, silicon carbide is formed.  

Si+C→SiC

By reducing silica with coke, crystalline silicon is produced. In the absence of air, surplus silica is burned with coke in an electric furnace to produce dark grey-colored silicon in its crystalline form.
