An electrochemical cell is constructed in which both electrodes are made of platinum, but in which one electrode is in contact with an aqueous solution containing [Fe2+]=0.0765M and [Fe3+]=0.176M while the other electrode is in contact with an aqueous solution containing [Ce4+]=0.0376M and [Ce3+]=0.0987M. The two half-cells are connected with a salt bridge of saturated KNO3.What is the potential of this cell at 35.0°C? What is K value for net cell reaction at 35.0°C?
if the reaction produces 5.72 grams of a compound called magnesium ammonium phosphate,MgNH4PO4. what is the percentage of phosphorus in the original plant food sample?
