5. Balance each skeleton reaction, calculate Ecell and state whether the reaction is Ecell-E camade - Eanode spontaneous: a) Cl₂ (g) + Fe2+ (aq) → Cl(aq) + Fe³+ (aq) Cl₂(g) 2Fe²(ag) 2015 (99) + 2 Fe³+ (aq) Eᵒcul = 1.398V-6.771V = +6.587 V spontaneous b) Mn²+ (aq) + Co³3+ (aq) → MnO2 (s) + Co²+ (aq) [acidic] Mn²+ (aq)+220 ²+ (aq) + 2H₂0 (2) → MnO₂ (s) + 200² (99) + 4H+ +059v spontaneous Ecell 1.82V-123V c) MnO₂ (s) + Agt (aq) →MnO4 (aq) + Ag (s) [basic] d) Co(s) + H+ (aq) → Co²+ (aq) + H₂ (g) e) 2H+ (aq) + H₂O2 (aq) +2Fe²+ (aq) → 2Fe³+ (aq) + 2H₂O (1) nằm
