In a fuel cell `H_(2)` and `O_(2)` react to produce electricity. In the process `H_(2)` gas is oxidised at the anode and `O_(2)` is reduced at the cathode. If 6.72 litre of `H_(2)` at NTP reacts in 15 minute, what is the average current produced ? If the entire current is used for electro-deposition of Cu from `Cu^(2+)`, how many g of Cu are deposited ?

In fuel cell H_(2) and O_(2) react to produce electricity. In the process, H_(2) gas is oxidised at the anode and O_(2) at cathode. If 44.8 litre of H_(2) at 25^(@)C and also pressure reacts in 10 minutes, what is average current produced? If the entire current is used for electro deposition of Cu from Cu^(2+) , how many grams of Cu deposited?

CaC_(2) and H_(2)O react to produce:

In a fuel cell, hydrogen and oxygen react to produce electricity. In the process hydrogen is oxidised at the anode and oxygen at the cathode. If 67.2 L of H_2 , at STP react in 15 minutes, what is the average current produced. If the entire current is used for electro deposition of copper from copper (II) solution, how many grams of copper will be deposited?
