    Written summary The reaction time test that had taken place involved the students to sit at a laptop and press the go button on the screen with their touch pad and wait for the stimulus to appear on the screen. When this stimulus would appear the student would then have to press on their touchpad with their writing hand and the amount of time that it took for the student to react to the stimulus and press the touchpad was the reaction time that was timed. The test was taken 3 times and the average

    Breland Crudup December 9‚ 2012 The Effects of Music on Reaction Time in Human Beings The Effects of Music on Reaction Time in Human Beings When performing many feats of physical skill‚ calculating how fast a person can perform the action has become a custom that has gained prominence in recent years. Observing how long it takes a person to perform an action‚ now known as observing the reaction time‚ has even gained enough importance to the point that it has even used in some scientific investigations

    Does age affect reaction time? Aim: To find out if age affects reaction time through the use of an online program created by Human Benchmark Background information: in a study conducted by the University of Michigan‚ the most accepted theory for the effect of age on reaction time is that older people have a slower reaction time in comparison to people of a younger age. This is because adrenaline levels and reflexes are in best condition when young. Another reason of reaction times decreasing with

    Ice Calorimeter Determination of Reaction Enthalpy Shannon Wedepohl 9/17/13 Abstract: During this experiment‚ an ice calorimeter was used to measure the change in volume in milliliters of magnesium metal and 1.00 M of sulfuric acid. We found the experimental molar enthalpy of the reaction to be ∆H = -370 ± 1 kJ/mol at 0˚C. This compares with an expected value of -466.9 kJ/mol at 25 ˚C‚ a 20.75% difference. Introduction: Many chemical reactions truly only encompass changes by

    This experiment was a Landolt Iodine clock reaction - Oxidation of Bisulphite by Iodate. It involved conducting three measured experiments. The first variable tested was concencentration. This was tested by conducting two experiments‚ each varying the concentration of either the NaHSO3 or KIO3. The varying of NaHSO3 involved using 0.1 Molar of KIO3 against decreasing concentrations of NaHSO3 (0.25 M‚ 0.125 M‚ 0.0625 M and 0.03125 M). When decreasing the concentration of KIO3‚ 0.25 M of NaHSO3 was

    The graph for run 1‚ which plotted ln(Abs at 595nm) versus time‚ a first order reaction‚ with an R^2 value of 0.99621 was the most linear. Therefore‚ crystal violet is a first order reaction. The observed rate constant from run 2‚ as shown in figure 4‚ was significantly lower then the observed rate constant from run 1‚ shown in figure 1. Therefore‚ the R^2 for the first order reaction for run 2‚ 0.946418‚ represented in figure 4‚ which is also extremely low‚ was not taken into consideration for calculations

    Title: Relativities of Alkyl Halides in Nucleophilic Substitution Reactions Introduction: The purpose of this lab was to perform a comparison of relative reactivities of various alkyl halides with two different reagents‚ sodium iodine in acetone and silver nitrate in ethanol. (Below are the reaction equations). We used different substrates‚ which were primary‚ secondary‚ and tertiary. These substrates included 2-bromobutane‚ 2-bromo-2-methylpropane‚ 1-bromobutane ∞-Bromotoluene‚ bromobenzene

    Prof. K. M. Muraleedharan Aromatic electrophilic substitution (Ar-SE) Reactions The special reactivity of aromatic systems towards electrophiles arises mainly from two factors: the presence of π electron density above and below the plane of the ring - making it nucleophilic‚ and the drive to regain the aromatic character by opting for substitution as opposed to a simple addition reaction. Preference towards addition reactions in the case of alkenes and substitution in the case of aromatic compounds

    8.07 Work File: Oxidation Reduction Reactions 1. What is the difference between an oxidizing agent and a reducing agent? The oxidation number (overall charge of the atom) is reduced in reduction and this is accomplished by adding electrons. The electrons‚ being negative‚ reduce the overall oxidation number of the atom receiving the electrons. Oxidation is the reverse process: the oxidation number of an atom is increased during oxidation. This is done by removing electrons. The electrons‚ being
