Question

Use the chemical equation to answer the question.

2Ag(s) + H2S(g) → Ag2S(s) + H2(g)

Does this equation represent a redox reaction?

(1 point)

No, it does not because neither hydrogen (H) nor silver (Ag) transfers electrons.

Yes, it does because silver (Ag) undergoes reduction and hydrogen (H) undergoes oxidation.

Yes, it does because hydrogen (H) undergoes reduction and silver (Ag) undergoes oxidation.

No, it does not because sulfur (S) does not change oxidation states.

Answer 1

Yes — hydrogen is reduced and silver is oxidized. Ag goes 0 → +1 (oxidation); H goes +1 → 0 (reduction), so this is a redox reaction (choose the option stating H is reduced and Ag is oxidized).
