Carbon disulfide is an important industrial solvent. It is prepared by the reaction of carbon (called coke) with sulfur dioxide.

Carbon monoxide is also produced (as a byproduct) of this reaction. (a) Write the equation that correctly demonstrates this reaction and balance it. (b) How many moles of carbon are needed to produce 45.90 moles of carbon disulfide?

Answer:

A. The balanced equation is given below:

5C + 2SO2 —> CS2 + 4CO

B. 229.5 moles of carbon.

Explanation:

A. Step 1:

The equation for the reaction is given below:

C + SO2 —> CS2 + CO

A. Step 2:

Balancing the equation.

The above equation can be balanced as follow:

There are 2 atoms of S on the right side and 1 atom on the left side. It can be balance by putting 2 in front of SO2 as shown below:

C + 2SO2 —> CS2 + CO

There are 4 atoms of O on the left side and 1 on the right. It can be balance by putting 4 in front of CO as shown below:

C + 2SO2 —> CS2 + 4CO

There are a total of 5 atoms of C on the right side and 1 atom on the left. It can be balance by putting 5 in front of C as shown below:

5C + 2SO2 —> CS2 + 4CO

Now the equation is balanced

B. Determination of the number of moles of carbon needed to produce 45.90 moles of carbon disulfide.

This is illustrated below:

5C + 2SO2 —> CS2 + 4CO

From the balanced equation above,

5 moles of C produced 1 mole of CS2.

Therefore, Xmol of C will produce 45.90 moles of CS2 i.e

Xmol of C = 5 x 45.90

Xmol of C = 229.5 moles

229.5 moles of carbon is needed to produce 45.90 moles of carbon disulfide.

Calculate the entropy change for the surroundings of the reaction below at 350K: N2(g) + 3H2(g) -> 2NH3(g) Entropy data: NH3
krek1111 [17]

Answer : The entropy change for the surroundings of the reaction is, -198.3 J/K

Explanation :

We have to calculate the entropy change of reaction (\Delta S^o).

\Delta S^o=S_{product}-S_{reactant}

\Delta S^o=[n_{NH_3}\times \Delta S^0_{(NH_3)}]-[n_{N_2}\times \Delta S^0_{(N_2)}+n_{H_2}\times \Delta S^0_{(H_2)}]

where,

\Delta S^o = entropy of reaction = ?

n = number of moles

\Delta S^0{(NH_3)} = standard entropy of NH_3

\Delta S^0{(H_2)} = standard entropy of H_2

\Delta S^0{(N_2)} = standard entropy of N_2

Now put all the given values in this expression, we get:

\Delta S^o=[2mole\times (192.5J/K.mole)]-[1mole\times (191.5J/K.mole)+3mole\times (130.6J/K.mole)]

\Delta S^o=-198.3J/K

Therefore, the entropy change for the surroundings of the reaction is, -198.3 J/K

Which of the following statements about the formation of a solution is true?
bekas [8.4K]

<span>In the formation of a solution, energy is required to overcome the forces of attraction between the solvent particles. The first step is for the solvent particles to move in order for solute particles to enter the system. This process is endothermic where energy flows into the system. The second step is when solute particles must separate from other solute particles. Lastly, the solute should move between solvent particles.</span>
