One of the primary substances used in sandpaper is Silicon carbide, SiC. It is produced by heating silicon dioxide, SiO2, with Carbon in a high intensity furnace. The other product is carbon monoxide, CO. What is the percent yield when 180 grams of SiC is produced from the reaction of 258.9 grams of carbon with 379 grams of SiO2? 1SiO2 (s) + 3C (s) → 1SiC (s) + 2CO (g)
