Hey im stuck on this sheet :) (no explanation or diagram needed)

If the concentration of OH is 2.7 × 10 mol/L, what would the pH be? a. b. C. d. Given the following half-cell reactions: (aq) + 2e → a. نه ن ن 9.43 8.63 8.57 9.36 C. e. C₁³+ (29) +1.18 V -0.30 V -1.18 V Fell + 3e¯ → Cr(s) Fe²+ (Aq) 2+ 1M Fe At 25°C, the initial cell voltage of the cell shown in the diagram above is E = -0.44 V E = -0.74V b. d. Cr Cr3+ (Aq) +0.30 V +1.34 V 1M
