Question

2
select the correct answer.
carbon disulfide is formed by the reaction of coke (carbon) with sulfur dioxide. how many moles of cs₂ will be generated if 8.0 moles of coke react with a surplus of sulfur dioxide?
5c + 2so₂ → cs₂ + 4co
○ a. 0.8 moles
○ b. 1.6 moles
○ c. 3.2 moles
○ d. 6.4 moles

Explanation:

Step1: Identify mole ratio

From the balanced equation \(5C + 2SO_2
ightarrow CS_2 + 4CO\), the mole ratio of \(C\) to \(CS_2\) is \(5:1\).

Step2: Set up proportion

Let \(x\) be the moles of \(CS_2\). Using the ratio \(\frac{5\space mol\space C}{1\space mol\space CS_2}=\frac{8.0\space mol\space C}{x}\).
Cross - multiply: \(5x = 8.0\times1\).
Solve for \(x\): \(x=\frac{8.0}{5}=1.6\).

Answer:

B. 1.6 moles
