(a)

Answer to Problem 11PP
The balanced chemical equation is shown below:
Explanation of Solution
The given chemical equation is shown below:
The coefficient of two is multiplied with methane and carbon disulfide and the coefficient of four is multiplied with hydrogen sulfide to balance the chemical equation.
(b)
Interpretation:
The
Concept introduction:
According to law of conservation of mass it is not possible to form the mass or to destroy the mass. The mass always remains conserved.
The number of moles is calculated as shown below:
(b)

Answer to Problem 11PP
The number of moles of carbon disulfide produced is
Explanation of Solution
The balanced chemical equation is shown below:
The above equation shows that two moles of methane reacts with one mole of octasulfur to form two moles of carbon disulfide and four moles of hydrogen sulfide.
Therefore, the number of moles of carbon disulfide produced is,
