Problem- A: Since we are so concerned about global warming, determine the amount of heat in Joules produced by the Apollo 9 Saturn Rocket. In this problem, you will have to determine what the limiting reagent is, the fuel or the LOX; from there you may determine the ?Hf. Of course pay close attention to set up and significant figures. Problem B: Determine the Liters of Water vapor produced during the burn. Some Assumptions: Ground Temperature: 23.00 C Ground pressure: 1.00 atm Kerosene is 100% - C12H26 1 liter of kerosene = 800.00 grams Oxygen makes up 20.95% of Air
