Read the following passage and answer the next five questions based on it.
Battery or cell converts chemical energy of the redox reaction to electrical energy. In fuel cell (a galvanar cell), the chemical energy of combustion of fuels like H₂, ethanol, etc. are directly converted to electric energy. In a fuel cell, H₂ and O₂ react to produce electricity, where H₂ gas is oxidised at anode and oxygen is reduced at cathode and the reactions involved are
The number of moles of hydrogen oxidised is:
1) Question

2) Question
The number of moles of electrons produced in the oxidation of 67.2 L of H₂ at STP is:
Correct option is D
3) Question
The quantity of electricity produced in the oxidation of 67.2 L of H₂ at STP is:
Correct option is B
4) Question
If the entire current produced is used for the electrodeposition of Silver (at.wt. 108 g mol-¹) from Si solution, the amount of silver deposited will be:
Correct option is B
5) Question
The source of electrical energy on the Apollo moon flight was:
Correct option is D
The Apollo Command Module's primary source of electric power was from a set of three "fuel cells" housed in the Service Module. Each fuel cell combines hydrogen and oxygen to produce electricity and water. The water was used for drinking by the astronaut crew.
