Transcribed Image Text:Which of the following represents a balanced half-reaction for the following when
balanced in acidic conditions?
MnO2(aq) → Mn²(aq)
SH+MnO,(aq)→→ Mn2+ (aq) + 4H₂O(el) + Se-
SH*+MnO2(aq) + 7e → Mn²+ (aq) + 4H₂O(el)
SH*+MnO2(aq) + Se →
Mn²+ (aq) + 4H₂O(el)
4H* + MnO2(aq) + 3e → Mn2+ (aq) + 2H₂O(el)
SH*+MnO(aq) → Mn(aq) + 4H₂O(el) + 7e-
