Agalvanic cell cr(s)cr2 (aq) | sn2*(aq)sn(s) is constructed using a completely immersed cr electrode that weighs 34.7 g and a sn electrode immersed in 500 ml of 1.00 m sn2(aq) solution. a steady current of 0.0758 a is drawn from the cell as the electrons move from the cr electrode to the sn electrode (a) which reactant is the limiting reactant in this cell? enter symbol (b) how long does it take for the cell to be completely discharged? (c) how much mass has the sn electrode gained when the cell is completely discharged? (d what is the concentration of the sn2+(aq) when the cell is completely discharged? assume that the limiting reactant is 100% reacted.
