a) b) Solve the following queries. Make sure to show complete procedure Calculate the standard emf of a cell that uses the Mg/Mg2+ and Cu/Cu²+ half-cell reactions at 25°C. Write the equation for the cell reaction that occurs under standard-state conditions. Consider the following half-reactions: MnO4 (aq) + 8H+ (aq) + 5e¯ →→Mn²+ (aq) + 4H₂O(1) NO3(aq) + 4H+ (aq) + 3e¯ →NO(g) + 2H₂O(1) Predict whether NO3 ions will oxidize Mn²+ to MnO4 under standard-state conditions. The equilibrium constant for the reaction c) Sr(s) + Mg2+ (aq) →→→→Sr²+ (aq) + Mg(s) is 2.69 x 10¹2 at 25°C. Calculate Eº for a cell made up of Sr/Sr²+ and Mg/Mg²+ half- cells.
