Question

Silicon is often used in computer chips. To obtain pure silicon, chemists can reduce SiCl4 with magnesium, as shown in the equation.

SiCl4 + 2Mg= Si + 2MgCl2

A computer chip manufacturer is interested in buying the process that a chemist is using to make pure silicon. In the demonstration of the process, the chemist uses 200.0 g of SiCl4 to produce 25.0 g of silicon. If the manufacturer wants a process that is efficient and cost effective, should it purchase the process that this chemist demonstrates?
