consider the following reaction 2H2(g)+O2(g)--> 2H2O (I) delta H= -572KJ A) how much heat is evolved when 1.00 mole of H2O (I) is produced? B) how much heat is evolved when 4.03g H2 are reacted with 40.0g of O2? C) the total volume of hydrogen gas needed to fill the Hindenburg was 2.0*10^8 L at 1.0 atm and 25 degree C. How much HEAT was evolved when the Hidenburg exploded, assuming all of the hydrogen reacted (plenty of oxygen)?

1. The reaction N2 + 3 H2 2NH3 is used to produce ammonia. When 450. g of hydrogen is reacted with nitrogen, 2550 g of ammonia should be produced. If a chemist actually obtains 1,977 g of ammonia in the lab, what is the percent yield of this reaction? Report your answer to the correct degree of certainty. Do not included units (% yield is understood). 2.Calculate the volume of 2.12 moles of nitrogen gas at temperature of 31.7 oC and a pressure of...

1.Calculate the free energy(ΔG°)of the following reactions: a)H2(g) + O2(g)→ H2O2(g) b)H2O2(g) + H2(g) → 2 H2O (g) How do the free energy values for these two reactions compare to the free energy of the combustion of hydrogen gas? Hint: (ΔG) is a state function, therefore Hess’s law is applicable.The combustion of hydrogen gas is modeled by the overall equation is 2 H2(g) + O2(g)→ 2 H2O(g). 2.Based on your calculations in the previous question and your understanding of reaction...
