Question: Consider the following reaction 2H2 g O2 g 2H2O l H

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 mole 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 × 108 L at 1.0 atm and 25oC. How much heat was evolved when the Hindenburg exploded, assuming all of the hydrogen reacted?
