Consider a magnesium–iron galvanic cell consisting of a magnesium electrode in a solution of 1 m mgso4 and an iron electrode in a solution of 1 m feso4. each electrode and its electrolyte are separated by a porous wall, and the whole cell is at 25°c. both electrodes are connected with a copper wire.
(a) which electrode is the anode?
(b) which electrode corrodes?
(c) in which direction will the electrons flow?
(d) in which direction will the anions in the solutions move?
(e) in which direction will the cations in the solutions move?
(f ) write the equation for the half-cell reaction at the anode.
(g) write the equation for the half-cell reaction at the cathode.

Acommercial grade cubical freezer, 4 m on a side, has a composite wall consisting of an exterior sheet of 5.0-mm thick plain carbon steel (kst= 60.5 w/m k), an intermediate layer of 100-mm thick polyurethane insulation (kins 0.02 w/m k), and an inner sheet of 5.0- mm thick aluminium alloy (kal polyurethane insulation and both metallic sheets are each characterized by a thermal contact resistance of r 2.5 x 104 m2 k/w. (a) what is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 25°c and -5°c, respectively? (b) for power saving purpose, which wall material should be increased/reduced in. thickness in order to reduce 50% of the cooling load found in part (a)? redesign the thickness of the proposed material. 177 w/m-k). adhesive interfaces between the q=575.93 w
