Scene of the Crash

At 6:02 a.m. you and your team of medical examiners are called to the scene of a plane crash. You find evidence of a pre-crash explosion. At the site of the explosion, the following material has been found. Subsequent chemical analysis shows these percentages:C 37.01 % H 2.22 % N 18.5 % O 42.27 %Determine the empirical formula for the chemical compound that caused the plane to crash. Use the percentages listed above.The deceased passengers are found in and around the crash. They must be identified by the substances found in their belongings or in their bodies, since they are not recognizable and their dental records are not available. Upon further investigation one passenger was suspected of having been murdered before the crash: the time of death was approximated at one hour prior to the crash.

Your Job:

1. Use the percent composition data in Table 1 to determine empirical formulas for the compounds found with or in the passengers. Match these formulas with the identity of each compound listed in Table 2. 2. Use the personal data in Table 3 to make a probable identification of each passenger. 3. Figure out who was murdered and who is the most probable murderer. 4. Submit your results.

Use this data to determine the empirical formulas for each chemical compound. This can then be used to compare with Tabble 2 to name the chemical.

Use this Table to help determine which passenger had which chemicals and the Passenger Number for each person.
