Combustion of hydrogen produces electricity:
It would power a 100-watt (W) light bulb in 27.66 min.
Calculation:
At STP conditions, we know that 1 mole of any gas is contained in 22.4L.
So let's make the operation:
The volume of one mole of gas at STP is 22.4 L
Then, 13.0 L may be the volume for (13.0) /22.4 = 0.58 moles.
The total energy is released = 0.58 x 286 kJ
Total energy = 165.98 kJ
Energy = Power x time
Time = energy / power
where power = 100W = 100 J/s
Therefore, Time = 165.98 kJ/ 100J/s = 1659.8 sec
Time = 1659.8 sec / 60 min = 27.66 min
∴ Time = 27.66 min
