Reference no: EM13884612

Consider the following reaction: 2H2(g)+  O2(g) yields 2H2O(l); delta H=572 kJ . How much heat is evolved for the production of 1.00 mol of H2O(l )? b. How much heat is evolved when 4.03 g of hydrogen is reacted with excess oxygen? c. How much heat is evolved when 186 g of oxygen is reacted wih excess hydrogen? d. The total volume of hydrogen gas needed to fill the Hindenburg was 2.0  108 L at 1.0 atm and 25C. How much heat was evolved when the Hindenburg exploded, assuming all of the hydrogen reacted?
