The total volume of hydrogen gas needed to fill the Hidenbrug was 2.0e8 L at 1.0 atm and 25 degrees Celsius. How much heat was evolved when the Hidenburg exploded, assuming all the hydrogen reacted?
2.0e8 L H2/22.4 L H2 = 8.9e6 mol H2
For every 2 mol H2 used -572 kJ of energy is produced
-572 kJ/2 mol H2 = -2.86e2 kJ/mol
Now what do I do?
