Consider the following reaction:
2H2 (g) + O2 (g) 2H2O (l) ΔH = -572 kJ
a. How much heat is evolved for the production of 1.00 mol H2O (l)?
b. How much heat is evolved when 4.03 g hydrogen is reacted with excess oxygen?
c. How much heat is evolved when 186 g oxygen is reacted with excess hydrogen?
d. The total volume of hydrogen gas needed to fill the Hindenburg was 2.0 x 10
L at 1.0 atm
C. How much heat was evolved when the Hindenburg exploded, assuming all of the
