Consider the reaction: 2 SO2(g)+O2(g)→2 SO3(g) If 285.5 mL of SO2 reacts with 158.9 mL of O2 (both measured at 315 K and 50.0 mm
Tanzania [10]

Answer:

a. Oxygen is the limiting reagent. n_{SO_3}^{Theoretical}=8.096x10^{-4}mol SO_3

b. Y=58.9%

Explanation:

Hello,

a. Limiting reagent and sulfur trioxide's theoretical yield.

At first, we must compute the involved moles for both sulfur dioxide's and oxygen's as follows, considering the volumes in liters and the pressure in atm of 50.0mmHg*1atm/760mmHg=0.0658atm:

n_{SO_2}=\frac{PV}{RT}=\frac{0.0658atm*0.2855L}{0.082\frac{atm*L}{mol*K}*315K} =7.273x10^{-3}molSO_2 \\n_{O_2}=\frac{PV}{RT}=\frac{0.0658atm*0.1589L}{0.082\frac{atm*L}{mol*K}*315K} =4.048x10^{-4}molO_2

Afterwards, by considering the properly balanced chemical reaction:

2SO_2(g)+O_2(g)-->2SO_3

We compute the oxygen's moles that completely reacts with the previously computed 7.273x10^{-3} moles of SO_2 as follows:

7.273x10^{-3}molSO_2*\frac{1molO_2}{2molSO_2} =3.6365x10^{-3}molO_2

That result let us know that the oxygen is the limiting reagent since just 4.048x10^{-4} moles are available in comparison with the 3.6365x10^{-3} moles that completely would react with 7.273x10^{-3} moles of SO_2.

Now, to compute the theoretical yield of sulfur trioxide, we apply the following stoichiometric relationship:

n_{SO_3}^{Theoretical}=4.048x10^{-4}molO_2*\frac{2molSO_3}{1molO_2} =8.096x10^{-4}mol SO_3

b. Percent yield.

At first, we must compute the collected (real) moles of sulfur trioxide:

n_{SO_3}^{real}=\frac{PV}{RT}=\frac{0.0658atm*0.1872L}{0.082\frac{atm*L}{mol*K}*315K} =4.769x10^{-4}molSO_3

Finally, we compute the percent yield:

Y=\frac{n_{SO_3}^{real}}{n_{SO_3}^{Theoretical}} *100%

Y=\frac{4.769x10^{-4}mol SO_3}{8.096x10^{-4}mol SO_3} *100%

Y=58.9%

Best regards.

Plz help with this.....☺​
Elodia [21]

Answer:

There is this property called CATENATION which is basically the tendency of the atoms to bind to eachother. It is the MOST in the carbon after that silicon.

So the answer should Carbon atoms bond together to form groups of compounds.
