Part A Ammonia reacts with oxygen according to the equation 4NH3(g)+5O2(g)?4NO(g)+6H2O(g),?Hrxn=?906 kJ Calculate the heat (in kJ) associated with the complete reaction of 155 g of NH3.

Part B What mass of butane in grams is necessary to produce 1.5×103 kJ of heat? What mass of CO2 is produced? Assume the reaction to be as follows: C4H10(g)+132O2(g)?4CO2(g)+5H2O(g),?Hrxn=?2658 kJ
