Represent the cell formed by connecting SHE with Silver electrode if the Ag electrode is standard with E^ϴAg⁺/Ag = 0.80 V.

The standard electrode potentials of two electrodes are given as E^ϴ_Zn²⁺/Zn = -0.76 V and E^ϴ_Cu²⁺/Cu = 0.34 V. Write the reactions taking place at the two electrodes, if they are coupled to form a cell ?

Identify the correct statement regarding the effect of temperature on conductance:

1. Metallic conductance increases as temperature increases
2. Metallic conductance remains constant as temperature increases
3. Ionic conductance increases as temperature increases
4. Ionic conductance decreases as temperature increases
