question 263

Multiple Choice

What are appropriate methods for the generation of H₂S? Reaction 1: FeS(s) + 2 H⁺(aq) → H₂S(g) + Fe²⁺(aq)
Reaction 2: CH₃C(CS) NH₂(aq) + H₂O(l) + heat → CH₃(CO) NH₂(aq) + H₂S(aq)
Reaction 3: 3 S(g) + 2 H₂O(g) → SO₂(g) + 2 H₂S(g)
Reaction 4: 2 SO₂(g) + 2 H₂O(g) → 2 H₂S(g) + 3 O₂(g)
