Answer» Solution :`(Ato4),(Bto3),(Cto1,5),(Dto2)` (A) Leclanche cell: It is ALSO known as ddry cell. In which CYLINDER of Zn is used, which is ANODE and on anode has oxidation reactiong according to option number 4, which is as follows: `Zn_((S)) to Zn^(2+)+2e^(-)` (B) Ni-Cd cell : it is a secondary cell. Which can be recharge. (C) Fuel cell : In this cell, combustible ENERGY (Chemical energy) of fuels like hydrogen, methane, methanol etc. is directly converted into the electrical energy. * In Hydrogen fuel cell, in concentrated aqueous solution of NaOH, when hydrogen and oxygen gas is passed, then the following redox reaction is as follows: `2H_(2(g))+O_(2(g))to2H_(2)O_((L))` |
