Balanced reaction-:
SiO2(s)+2C(s)SiC(s)+2CO(g)
(a) 1mol of SiO2 reacts to give 1mol of SiC
So 60.08g SiO2 gives 42.08g SiC
50.0g SiO2  produces=42.08g SiC60.08g SiO250.0g SiO2
=35.019g
percent yield=actual yieldtheoretical yield100%
=32.2g SiC35.019 g100%
=91.95%
(b) Mass of CO formed
=228.01g CO60.08g SiO250.0g SiO2
=46.62g CO formed
