2. Where should the police and the FBI look for Brittany Evans? Be specific as possible cite evidence for your conclusions. 3. Describe the trace evidence that was found during the investigation of the Brittany Evans abduction. Explain how each piece of evidence would have been collected and processed and how investigators would avoid contaminating the trace evidence.

4. Explain how each piece of trace evidence collected during the investigation of Brittany Evans abduction was analyzed.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
