2 Name______________________________ 1. (30 points) You are operating a mobile lab for the United Nations in the Middle East and you come upon a cache of material that appears to be a high explosive. The only tool you have at your disposal is a bomb calorimeter (no pun intended), and you wish to determine whether the explosive is RDX (C 3 H 6 N 6 O 6 , MW = 222) or TNT (C 7 H 5 N 3 O 6 , MW=227) The known enthalpy of combustion of RDX is –2120 kJ/mol and that for TNT is –3410 kJ/mol. The calibration constant for your calorimeter is 17000 J/ K. You very carefully place a 1.00 g sample of the unknown explosive in the calorimeter and allow it to undergo combustion. For these reactions, you may assume E H, i.e., close enough for Government work. a)
