Answer» In MG-Al cell, the number of electrons involved in the cell reaction i s 0.25 mole of propane is subjected to combustion. If this reaction is used for MAKING a fuel,cell the number of moles of electrons involved in each HALF cell for this amount of propane will be Three litres of 0.5M `K_(2)Cr_(2)O_(7)` solution have to be completely reduced in the acidic medium. The number of faradays of electricity required will be For the Mg-Ag cell, how many times the difference between the EMF of the cell and its STANDARD EMF will change if concentration of `Mg^(2+)` ions changed to 0.1M and that of `Ag^(+)` ions is changed from 0.5M to 0.25M. Answer :A
