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, 155.6kg of SiO2 is allowed to react with 78.7kg of carbon to produce 66.1kg of silicon.

Part B

Determine the theoretical yield for the reaction.

Express your answer using four significant figures

Part C
