Chapter 4, Problem 4.35PAE

4.33 Silicon carbide, an abrasive, is made by the reaction of silicon dioxide with graphite (solid carbon):

   ${\text{SiO}}_{\text{2}}+\text{ C }\stackrel{\Delta }{\to }\text{SiC }+\text{ CO }\left(\text{balanced}?\right)$

We mix 150.0 g of SiO₂ and 101.5 g of C. If the reaction proceeds as far as possible, which reactant is left over? How much of this reactant remains?
