Answer:
Theoretical yield for Si = 2586.55*28.09= 72.7 Kg
Percentage yield is =2356.71/2586.55=91.11%
Explanation:
So the chemical equation for this reaction would be SiO2 + 2C = Si + CO
so n(SiO2)=m(SiO2)/M(SiO2)=155400/60.08=2586.55 mol
n(C)=m(C)/M(C)=77400/12.01=6444.63 mol
So Carbon is in exes.
n(Si)=m(Si)/M(Si)=66200/28.09= 2356.71 mol
Theoretical yield for Si = 2586.55*28.09= 72.7 Kg
Percentage yield is =2356.71/2586.55=91.11%
