Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces only nitrogen and water y transported. An industrial chemist studying this reaction fills a 500. mL. flask with 3.0 atm of ammonia gas and 3.0 atm of oxygen gas at 30. °C. He then...

E AFTER COMPLETING LAB. ANSWER IN SPACE PROVIDED. Suppose the heat of neutralization had been determined using a glass beaker instead of a polystyrene coffee cup How would the measured value have been affected? The heat of combustion of octane, C,H,. can be measured in a way similar to the method youC used to measure the heat of neutralization. The bomb calorimeter is used instead of a coffee cup. The reaction is 2C,H,1)+ 25 O, (g) 16 CO, (g) +...
