A stink bomb is composed of an aqueous solution of ammonium hydrosulfide. It is used as a malodorant and a riot control agent. What are the chemical reactions that lead to the compound/s responsible for the strong unpleasant smell of stink bombs?

• A. Generation of ammonium hydrosulfide:
  NH₃ (g) + H₂S (g) → NH₄SH (aq)
  Generation of stink bomb smell:
  NH₄SH (aq) → NH₄SH (g)
• B. Generation of ammonium hydrosulfide:
  NH₄ (g) + HS (g) → NH₄SH (aq)
  Decomposition of ammonium hydrosulfide:
  NH₄SH (aq) → NH₃ (g) + H₂S (g)
• C. Generation of ammonium hydrosulfide:
  NH₃ (g) + H₂S (g) → NH₄SH (aq)
  Decomposition of ammonium hydrosulfide:
  NH₄SH (aq) → NH₃ (g) + H₂S (g)
• D. Generation of ammonium hydrosulfide:
  NH₃S (l) + H₂ (g) → NH₄SH (aq)
  Decomposition of ammonium hydrosulfide:
  NH₄SH (aq) → NH₃ (aq) + H₂S (aq)

Answer: (C)
