The following thermodynamically favored reaction takes place in an acidified galvanic cell.

O2(g) + 2 H2S(g)  2 S(s) + 2 H2O(l)

a. What is the half reaction that takes place at the anode?

b. What is the half reaction the takes place at the cathode?

c. Calculate the standard cell potential, Eo

cell.

d. What must the partial pressures of the reactants be in order to produce the

voltage in part c?

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks. energy was destroyed inside the blocks. energy was absorbed into the blocks from outside the system. energy was transferred from the warmer block to the cooler block.
