Methane and sulfur react to produce carbon disulfide (CS₂), a liquid often used in the production of cellophane.

2CH₄ + S₈ --> 2CS₂ + 4H₂S

Calculate the moles of H₂S produced when 2.25 mol S₈ is used.

Answers

Answer:

9 moles

Explanation:

The balanced chemical equation provided in this question is as follows:

2CH₄ + S₈ → 2CS₂ + 4H₂S

In accordance to the above balanced equation, 1 mole of sulphur (S8) produces 4 moles of hydrogen sulfide (H2S).

Therefore, if 2.25mol of S8 is used, 2.25 × 4 = 9 mol

9 moles of H2S is produced.
