What is E° (cell) for the reaction 2 Au(s) + 3 Ca²⁺(aq) → 2 Au³⁺(aq) + 3 Ca(s)?

H₂(g) + F₂(g) → 2 H⁺(aq) + 2 F⁻(aq).

What species is/are formed at the anode of the alkaline fuel cell?

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25°C. (The equation is balanced.) 3 Cl₂(g) + 2 Fe(s) → 6 Cl^-(aq) + 2 Fe³⁺(aq) Cl₂(g) + 2 e^- → 2 Cl^-(aq) E° = +1.36 V Fe³⁺(aq) + 3 e^- → Fe(s) E° = -0.04 V

Determine E° (cell) for the reaction Al(s) + 3 Ag⁺(aq) → 3 Ag(s) + Al³⁺(aq).
