Silicon is the second most abundant element (~27.2%)in the earth's after oxygen (45.5 %) Carbon. Silicon, germanium, tin and lead constitute the group 14 of the periodic table. Chemistry of silicon is distinctly different from that of carbon. For example, under standard conditions CO_(2) is a gas whereas SiO_(2) is a covalent solid. In a silicon manufacturing unit, silicon is obtained by heating 100 kg of pure sand with 45 kg of high grade coke in an electric furnace. Write the balanced equation of the reaction.
