A voltaic cell is constructed from a standard Hg2+ | Hg half cell (E° red = 0.855V) and a standard F₂F¯ half cell (Eºred = 2.870V). (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is: + The cathode reaction is: + Submit Answer The spontaneous cell reaction is: + The cell voltage is Į V. Retry Entire Group + + + 8 more group attempts remaining Previous
