Scene of the crash
Click here for next task
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 a material has been found. Subsequent chemical analysis of the material shows it was:C-37.01% H-2.22% N-18.5% O-42.27% The mangled 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.

1) Use the percent composition data in Table 3 to determine formulas for the compounds found with or in the passengers. Show your work on paper and record the empirical formula in the column. Match these formulas with the identity of each compound listed in Table 1. Be certain to use the number of significant figures in the analysis to determine the number of significant figures you need to use from the periodic table. For example: If four significant figures are given in the data, use four significant figures from the periodic table. 2) Use the personal data in Table 2 to make a probable identification of each passenger. - Record the identifications on the Victim Identification Form. - Include the evidence that supports your identification. The solution to the mystery is the one that the evidence points to by logical deduction. Do not insert ideas not supported by the evidence.- Determine who was murdered.- Determine who is most likely to have committed the murder.- Determine the identity of the substance that was found at the site of the explosion.
