Many computer chips are manufactured from silicon, which occurs in nature as SiO2. When SiO2 is heated to melting, it reacts wit
Feliz [49]

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%

) determine the theoretical yield and the percent yield if 21.8 g of k2co3 is produced from reacting 27.9 g ko2 with 29.0 l of c
Airida [17]
The Balanced Chemical Equation is as follow;

                         4 KO₂  +  2 CO₂    →    2 K₂CO₃  +  3 O₂

First find out the Limiting Reagent,
According to equation,

         284 g (4 moles) KO₂ reacted with  =  44.8 L (2 moles) of CO₂
So,
                  27.9 g of KO₂ will react with  =  X  L of CO₂


Solving for X,
                          X  =  (44.8 L × 27.9 g) ÷ 284 g

                          X  =  4.40 L of CO₂

Hence, to consume 27.9 g of KO₂ only 4.40 L CO₂ is required, while, we are provided with 29 L of CO₂, it means CO₂ is in excess and KO₂ is is limited amount, Therefore, KO₂ will control the yield of K₂CO₃. So,

According to eq.

         284 g (4 moles) KO₂ formed  =  138.2 g of K₂CO₃
So,
         27.9 g of KO₂ will form  =  X g of K₂CO₃

Solving for X,
                        X  =  (138.2 g × 27.9 g) ÷ 284 g

                        X  =  13.57 g of K₂CO₃

So, 13.57 g of K₂CO₃ formed is the theoretical yield.

%age Yield  =  13.57 / 21.8 × 100

%age Yield  =  62.24 %
