Problem: Many computer chips are manufactured from silicon, which occurs in nature as SiO2. When SiO2 is heated to melting, it reacts with solid carbon to form liquid silicon and carbon monoxide gas. In an industrial preparation of silicon, 155.9 kg of SiO2 is allowed to react with 78.4 kg of carbon to produce 66.2 kg of silicon.Determine the theoretical yield for the reaction.
FREE Expert Solution
Balanced reaction will appear as:
SiO2 (l) + 2 C (s) → Si (l) + 2 CO (g)
MM of SIO2 → 60.08 g/mol
MM of C → 12.01 g/mol
MM of Si → 28.09 g/mol
Determine the limiting reactant:
