Carborundum is silicon carbide, SiC, a very hard material used as an abrasive on sandpaper and in other applications. It is prepared by the reaction of pure sand, SiO2, with carbon at high temperature. Carbon monoxide, CO, is the other product of this reaction. Write the balanced equation for the reaction, and calculate how much SiO2 is required to produce 3.00 kg of SiC.


Expert Answer

Step 1

The balanced equation for the reaction of Silicon dioxide (SiO2) with Carbon (C) is as follows:

SiC + 2CO SiO2 3C

Step 2

The molar mass of SiC is 40.11 g/mol. The moles of SiC in 3.0 kg or 300...
