DALERIN CARTER CJ370: CRIME SCENE INVESTIGATION 2 PROF: DENISE WOMER UNIT 5 ASSIGNMENT 1/9/2013 How to identify and dead body using only teeth! In this paper we will the many methods that crime scene techs and other people identify and person identity by only having their teeth. I would like to state that it is somewhat more challenging to do this with only someone teeth do to the fact that there is no database for people teeth only their x-ray’s and that’s if they have ever even been to the

1. Summary of Experiment In this experiment we will be comparing the both SN1 and SN2 reactions using various compounds and sodium iodide and silver nitrate. We will be comparing the nature of the leaving group (Cl vs Br) in the 1-halobutanes as well as the effect of the structure of the compound. The effect of the solvent polarity and temperature will also be looked

Introduction and Theory: A two dimensional object is a figure that has both width and height. Today in physics a two dimensional lab was done to decide the distance of an ice cream cone shooter. To do this‚ the formula (d=Ví t + (1/2) at^2) has to be implemented. I decided to make my Y equal to one meter‚ so my calculations would be easy to get. I knew my acceleration for Y was -9.8‚ the velocity initial for Y was zero‚ and the time it will take for the ice cream to reach zero is .452. For X I know
