Silicon carbide is an abrasive used in the manufacture of grinding wheels. A company is investigating whether they can be more efficient in the construction of such wheels by making their own via the following reaction. (a) If this reaction consistently has a yield of , what is the minimum amount (in ) of both silicon dioxide and carbon needed to produce of for the manufacture of cutting wheels? silicon dioxide kg carbon kg (b) The silicon dioxide is to be obtained from sand and the carbon is derived from coal. If the available sand is by weight and the coal is by weight, and assuming the other material does not interfere with the intended reaction, what mass of coal (in ) is needed for each metric ton of sand used? () kg
