**All questions on top part of the problem have been answered and solved, just need the last question in blue to be answered. Thank you! Choose which direction is spontaneous for the following reaction.  (Answer is: Forward) Calculate Eo for the spontaneous reaction.(Answer is E: 1.22V)  If you now calculate E using the Nernst equation, you find that E = 1.18 eV.  Calculate the concentration of Al3+ if the concentration of Fe2+ is 2.25M. (Answer is 11.22M) If you let this battery run at 3.6 amps, how long in minutes would you have to wait to lose 1.3 grams of your anode? (Answer is 77.4 minutes) Fe2+  +  Alo  <--->  Feo  +  Al3+ how many grams would you have gained on the cathode side during the same amount of time it took to lose the 1.3 grams of anode?

[References] a. An aqueous solution contains 3.45 g of iron(III) sulfate, Fe2 (SO4)3, per liter. What is the molarity of Fe2 (SO4)3 ? Molarity = M b. When the compound dissolves in water, the Fet ions and the SO4 ions in the crystal go into the solution. What is the molar concentration of each ion in the solution? Molar concentration = M Fe+ Molar concentration = M SO Submit Answer Try Another Version 6 item attempts remaining Visited Email l
