An alkaline battery has the overall reaction:

Zn + MnO2 + H2O → ZnO + Mn(OH)2 E°=1.5V

Part A: How many grams of Zn would be required in an alkaline battery that could power a 10 W device for 200 hours?

Part B: What is the current (in Amps) during this discharge?

The half-reactions that occur in ordinary alkaline batteries can be written as Cathode:MnO2(s)+H2O(l)+e−→MnO(OH)(s)+OH−(aq)Anode:Zn(s)+2OH−(aq)→Zn(OH)2(s)+2e− In 1999, researchers in Israel reported a new type of alkaline battery, called a "super-iron" battery. This battery uses the same anode reaction as an ordinary alkaline battery but involves the reduction of FeO2−4 ion (from K2FeO4) to solid Fe(OH)3 at the cathode. Part A Use the following standard reduction potential and any data from Appendixes C and D to calculate the standard cell potential expected for...
