    Experiment 1: Preparation of 1-Bromobutane and Reactivity of Alkyl Halides Objective: The purpose of this lab is to prepare 1-bromobutane from 1-butanol in an acid-catalyzed substitution reaction. While the reaction would be expected to occur as SN2 due to the primary nature of the substrate‚ because H2SO4 is used as a solvent‚ the conditions are very polar and the reaction can proceed via an SN1 reaction. The main objective is to obtain test results to determine the mechanism of the reaction

    Review: Csaba Szalay‚ Ildikó Ábrahám‚ Szilárd Papp‚ Gábor Takács‚ Balázs Lukáts Ágnes Gáti‚ and Zoltán Karádi‚ (2010). Taste reactivity deficit in anorexia nervosa. Psychiatry and Clinical Neurosciences‚ 64: 403–407. Basis for the research question in past research and theory: Hypogeusia‚ the reduced ability to taste‚ and dysgeusia‚ the distortion of the sense of taste‚ mainly involving the sour‚ bitter and salty tastes‚ have already been demonstrated in anorexia nervosa patients in literature

    Constant Density: Displacement of Zinc and Tin Introduction: Density is the concentration of molecules within an object on relation to its size. The formula for measuring density is mass/volume. In the experiment preformed for this lab report‚ calculating the density of a regular object (a wooden block) and two other irregular objects (zinc and tin) were found by a process known as water displacement. The purpose of this experiment was to prove that the density of an object remains the same

    Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy Curtis M. Franklin Thursday‚ February 14‚ 2013 ABSTRACT An ice calorimetric measurement was used to determine that a reaction involving solid magnesium metal and 1.00M sulfuric acid produces an experimental a value of ∆H = -226 ± 28 kJ/mol at 0°C. This is about 48.4% lower than the expected value reported at 25°C.  Introduction Many chemical reactions exhibit themselves by exchanging heat energy‚ either be absorbing

    Linear Variable Displacement Transducer (LVDT): A very basic transducer which is always useful in the field of instrumentation‚ I have studied about this in my college days. Now let me explain about the LVDT with its Principle of Operation and I will explain how it is constructed for its well known operation and you can understand the working of LVDT. Principle of LVDT: LVDT works under the principle of mutual induction‚ and the displacement which is a non-electrical energy is converted into an
