Carbon disulfide is prepared by heating sulfur and charcoal. The chemical equation is

S₂ (s) + C (s) → CS₂ (s).

Explanation:

Carbon disulfide is prepared by heating sulfur and charcoal. The chemical equation is:

S₂ (s) + C (s) → CS₂ (s).

1 mol of S₂ (s) reacts with 1 mol of charcoal (C (s)) to produce 1 mol of CS₂ (s).
