melting point of benzoic acid was observed in range 122 to 125 ¨¬C. By comparing melting point of benzoic acid (121 ¨¬C) with result from part A‚ the result is little higher than the pure melting point. So I can tell it is little contaminated. Identification of an unknown sample (compare its observed melting range with known compounds). Unknown #42 was found to have a melting range of 99 to 101 ¨¬C in 1st trial and 95 to 97 ¨¬C in 2nd trial. The only one given pure compounds with similar melting ranges

BIOMETRICS IDENTIFICATION ATTENDANCE MONITORING SYSTEM Time is a special resource that you cannot store or save for later use. Everyone has the exact same amount of time each day. Time not well used cannot be retrieved. Most people feel like they have too much to do and not enough time. They blame lack of time for their poor finances‚ unachieved goals‚ stress‚ bad relationships and not exercising their body. Wise time management can help you find the time for what you desire to do or need to

Identification of a Conjugated Diene from Eucalyptus Oil Purpose: The purpose of this experiment was to prepare the Diels-Alder adduct of the unknown Conjugated diene in eucalyptus oil‚ to separate the adduct‚ and identify the unknown diene from the melting point of it¡¯s adduct. Introduction: This experiment was performed using techniques of heating under reflux‚ vacuum filtration‚ recrystallization‚ and melting point measurements. These techniques were used to separate the Diels-Alder

ACCIDENT IDENTIFICATION SYSTEM USING GSM AND GPS Objective: The main objective of this project is to design and implement an accident identification system using GSM. Scope: GSM (Global System for Mobile communications: originally from Groupe Spécial Mobile) is the most popular standard for mobile phones in the world. Its promoter‚ the GSM Association‚ estimates that 82% of the global mobile market uses the standard. GSM is used by over 3 billion people across more than 212 countries

Abstract: A qualitative analysis experiment was conducted to determine the identity of an unknown aldehyde or ketone. The tests include a Tollens test‚ a Schiff test‚ an iodoform test‚ and a derivative melting point test. The data of the first three tests was inconclusive. The final derivative melting point test was utilized to successfully determine that the unknown was the ketone‚ Propiophenone. Introduction: Qualitative analysis is a method or series of methods used to determine the

Discussion for Experiment 1 (Basic Laboratory Operations and Identification of a compound : Chemical Properties) In the first experiment‚ the precision of instrument was studied by measuring the mass of water for several times. The result shows that the mass measurement of the balance is precise since the masses of water in six trials are somewhat close. The reason that the masses of water in each trial are not identical may come from the high sensitivity of the balance that keep fluctuating due

KM Systems – Spring 2013 Task: Within an industry or subject field‚ find a taxonomy that you might employ with a KM effort in an organization within that industry/field. Tell me how you found the taxonomy/thesaurus and the features you think that make it a good choice. Identify (at least) one aspect that you might change. I chose to think about a Medical Device firm and looked for a taxonomy that might be employed. Using Google Scholar I found an article published in the Journal of Knowledge
