1. Balanced Chemical Equation:

The reaction between coke (carbon) and sulfur dioxide (SO₂) to produce carbon disulfide (CS₂) is:

```

C (s) + 2 SO₂ (g) → CS₂ (g) + 2 CO₂ (g)

```

2. Mole Ratio:

The balanced equation shows that 1 mole of carbon (C) reacts to produce 1 mole of carbon disulfide (CS₂).

3. Moles of Carbon:

* Assume "8.0 coke" refers to 8.0 grams of coke.

* Molar mass of carbon (C): 12.01 g/mol

* Moles of carbon: (8.0 g) / (12.01 g/mol) = 0.67 mol

4. Moles of Carbon Disulfide:

Since the mole ratio is 1:1, 0.67 moles of carbon will produce 0.67 moles of carbon disulfide (CS₂) .
