A sample containing 37.4 grams of ammonia undergoes combustion with excess oxygen in a bomb (constant volume) calorimeter to form nitrogen monoxide (nitric oxide) and water gas. The heat constant for the calorimeter (Ccal) is 952 J/Â°C. The specific heat capacity for water vapor is 2.00 J/ gÂ°C. The specific heat capacity for nitrogen monoxide is 0.996 J/ gÂ°C. During the experiment, the temperature in the calorimeter changes from 22.9Â°C to 1772.9Â°C. qcal = -qrxn
qcal = Ccal Î”T

a. Give the balanced chemical equation that represents this reaction and calculate the number of grams for each product produced.
b. Calculate the amount of heat transferred during this reaction. Be certain to include units and the correct number of significant figures. Ignore the effects of excess oxygen in the bomb calorimeter.
c. Calculate the change in enthalpy in kJ/mol ammonia for this reaction.
d. Is the change in enthalpy equal to the change in internal energy for this reaction? Explain your answer.
e. How would the change in enthalpy for this reaction differ, if the reaction was allowed to occur in an open reaction vessel? Explain
