Calculate the standard entropy change for the reaction 2H2(g) + O2(g) → 2H2O(g) given the standard entropy values of H2(g) = 130.6 J/mol K, O2(g) = 205.0 J/mol K, and H2O(g) = 188.8 J/mol K. Also, determine whether the reaction is spontaneous or not at 298 K.

A student wants to determine the concentration of silver ions (Ag+) in a solution. Using an Ag/Ag+ reference electrode, the student measures the cell potential to be +0.56 V when the solution is electrolyzed for 25 minutes at a constant current of 0.50 A. The volume of the solution is 150 mL. What is the concentration of silver ions in the solution in mol/L?
