– Identifying Bacteria Bacteria identification is accomplished in a number of ways. Two common tools microbiologists use to identify unknown bacteria include dichotomous key and biochemical tests. The dichotomous key is useful when a microbiologist only needs to know which group an unknown microbe belongs to on a general level. When a microbiologist needs to identify a specific bacterium‚ biochemical tests are used. PART ONE: GENERAL BACTERIA IDENTIFICATION Review the dichotomous key in Figure

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

Identification of a Hydrate Based on Percent Water Varun Wadhwa 11/19/12 Introduction The identity of an unknown hydrate was determined by massing the hydrate before and after heating and calculating the percentage of water. Procedure First‚ we cleaned‚ dried and heated an evaporating dish for five minutes on an iron ring with the Bunsen burner and massed it. Then‚ we added 2 grams of an unknown hydrate and calculated the mass of that. Next‚ we used gradually increasing heat for

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

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

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
