Physical Properties of Organic Molecules Abstract Identifying the physical properties of compounds can be useful in several ways. It helps us to determine the structure of certain compounds‚ the purity of substances and if a substance is not pure we can figure out how to separate contaminating substances from a compound. In this experiment‚ I learned how to determine a solid’s melting point and why some melting point ranges may be broader than others.

Abstract Ever since there has been crime there has been Crime Scene Investigations (CSI). Throughout the 1900’s and continuing into current day‚ technological advancements in CSI have been taken for granted. In the past‚ law enforcement (LE) agencies and investigators were not capable of having regular access to the tremendous amount of information that can be found and analyzed from a crime scene. Present days CSIs typical “tools of the trade” range from flat out boring every day devices to the

The first property of water is that it is an excellent solvent. This is because of the chemical composition and physical attributes of water. Since water is polar‚ it allows water molecules to become attracted to different molecules. The attraction can be so powerful that it can disrupt the attractive forces of the different molecules. For example‚ water can be heavily attracted to salt that it can disrupt the forces that hold sodium and chloride‚ therefore dissolving it. The second property of water

This essay assesses property dualism‚ a theory of mind. It proclaims the existence of a single‚ physical substance (unlike Cartesian dualism)‚ but argues that this single substance has two potential properties: physical and mental states that are not reducible. The idea that mental states are non-reducible properties of brain states is the central tenant of a theory of mind called property dualism. However‚ before we can assess the theory we must be aware that the question assumes the existence

| Crime Scene Investigation | Case Study #1 | | | 1/26/2013 | OBTAINING and RECORDING PHYSICAL EVIDENCE When it comes to identifying people that have committed a criminal act‚ the most positive means is through fingerprints. When we are born‚ our fingerprints stay with us until we die and our bodies start decomposing. To the human eye our fingerprints look the same‚ however‚ further investigation will show that each of us have a unique set of friction ridges that comprise our

In this paper‚ I will give the Department of Defense (DoD) definition of accountability and responsibility while explaining the importance of maintaining positive physical security of a Common Access Card (CAC) which is a piece of the “intelligence puzzle” and vital to Operational Security (OPSEC). The paper will give examples of how the lack of positive security of a CAC can‚ not only‚ diminish a soldier’s ability to perform daily tasks‚ but also limit their access to information pertinent to the

Jordan Toschak Kevin Hannon and Megan Blanford Physical Properties of Clusters of Galaxies Monday (4/15/2013) Procedure For this experiment‚ a photograph of the Virgo Cluster of Galaxies will be needed to observe. The photograph will be sectioned into specific areas with coordinates like a map. Locate the area and identify the galaxies. Classify the galaxies as elliptical‚ spiral‚ or irregular. An elliptical galaxy will appear solid with not real defined “arms” or spirals coming from the

Crime Scene Investigations by First Responders Crime scenes contain the forensic evidence required to apprehend criminals. The proper collection and processing of physical evidence is of primary importance to most police investigations. Evidence can not only establish the fact of the offense and identify the perpetrator; it may even lead to a conviction. In collecting this evidence we must be conscious of the public’s Fourth Amendment rights and not violate them in this collection of evidence. Unfortunately

Time does fly so fast that today’s innovation is inclusive. With these innovations‚ some creates originally and some just imitates these originals. And with the intellectual property law‚ owners are granted certain exclusive rights to a variety of intangible assets.

Properties of Substances- Gr.12 Chemistry Final Lab Report Lab: Properties of Substances M. Nguyen SCH4U April 27‚ 2012 Abstract The purpose of this experiment was to use a variety of tests to identity the type of bonds which are present in each solid. Various substances (paraffin wax‚ sucrose‚ sodium chloride‚ tin‚ and silicon dioxide) were experimented and identified with tests for hardness‚ solubility‚ conductivity‚ and the time for the solid to melt with a candle and Bunsen burner
