Thank you for the help! For part (b), please answer with the correct number of significant figures. Thank you!!

Carborundum (silicon carbide), SiC, is a very hard material used as an abrasive on sandpaper and in other applications. It is prepared by the reaction of pure sand, SiO 2, with carbon at high temperature. Carbon monoxide, CO, is the other product of this reaction. (a) Write the balanced equation for this reaction. (Omit states-of-matter from your answer. Use the lowest possible whole number coefficients.) (b) Calculate how many kilograms of SiO2 are required to produce 3.51kg of SiC
