Half-ReactionE°(volts)Cd(OH)2(s) + 2 e¯ ---> Cd(s) + 2 OH¯(aq)- 0.809NiOOH(s) + H2O(l) + e¯ ---> Ni(OH)2(s) + OH¯(aq)+ 0.490a) Write a balanced equation for the process that produces electricity ina nicad battery and specify the half-reaction that occurs at the anode.b) Calculate the potential expected for a nicad battery.c) If such a battery produces a current of 50 milliamps for a period of 6.00 hours, how many electrons will be transfered?d) What mass of cadmium will undergo oxidation (or reduction) during the process in part (c)?5. (14%) Write net equations for each of these reactions. Use appropriate ionic and molecular formulas for the reactions andproducts and omit formulas for all ions or moleculs that do nottake part in a reaction. Write structural formulas for all organicsubstances. You need not balance the equations. All reactions occur in aqueous solution unless otherwise indicated.
