In the manufacturing process of sulfuric acid, sulfur dioxide is reacted with oxygen to produce sulfur trioxide. Using the equat

ion, 2SO2 (g) + O2 Imported Asset 2SO3 (g), if 64.06g of sulfur dioxide is given an opportunity to react with an excess of oxygen to produce 75.00 g of sulfur trioxide, what is the percent yield of this reaction? 46.83% 60.25% 75.55% 93.68%

Answer : The percent yield of the reaction is, 93.68 %

Explanation :  Given,

Mass of SO_2 = 64.06 g

Molar mass of SO_2 = 64 g/mole

Molar mass of SO_3 = 80 g/mole

First we have to calculate the moles of SO_2.

\text{Moles of }SO_2=\frac{\text{Mass of }SO_2}{\text{Molar mass of }SO_2}=\frac{64.06g}{64g/mole}=1.0009mole

Now we have to calculate the moles of SO_3.

The balanced chemical reaction will be,

2SO_2+O_2\rightarrow 2SO_3

From the balanced reaction, we conclude that

As, 2 moles of SO_2 react to give 2 moles of SO_3

So, 1.0009 moles of SO_2 react to give 1.0009 moles of SO_3

Now we have to calculate the mass of SO_3

\text{Mass of }SO_3=\text{Moles of }SO_3\times \text{Molar mass of }SO_3

\text{Mass of }SO_3=(1.0009mole)\times (80g/mole)=80.072g

The theoretical yield of SO_3  = 80.072 g

The actual yield of SO_3  = 75.00 g

Now we have to calculate the percent yield of SO_3

\%\text{ yield of the reaction}=\frac{\text{Actual yield of }SO_3}{\text{Theoretical yield of }SO_3}\times 100=\frac{75.00g}{80.072g}\times 100=93.68\%

Therefore, the percent yield of the reaction is, 93.68 %

The formula for chlorine acid is
fenix001 [56]

The correct terminology for chlorine acid is Hydrochloric Acid. The formula for that is HCl. This is because H has an ionic charge of +1 and Cl has an ionic charge of -1. Thus, they will combine to form HCl. Also, H is in front because almost all acids will have H in front.

The wavelength of light : 4.14 x 10⁻⁵ m

<h3>Further explanation </h3>

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

\large{\boxed{\bold{E\:=\:h\:.\:f}}}

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

The energy of the light = 4.8 x 10⁻²¹ J

The wavelength of light :

\tt E=h.\dfrac{c}{\lambda}\\\\\lambda=\dfrac{h.c}{E}\\\\\lambda=\dfrac{6.626.10^{-34}\times 3.10^8}{4.8.10^{-21}}\\\\\lambda=4.14.10^{-5}~m

Vesna [10]
You just need to convert it into moles per Liter (mol/L).

0.0815mol / 0.550L = 0.148mol/L
