    Korleyfah Mouth Chem 331 Thursday 2:00pm Dr. Lijuan Li 20A Preparation of CuCl2~2DMSO 20B Preparation of RuCl2~4DMSO Abstract In order to synthesize our metal complexes‚ we were able to make both Copper and Ruthenium metals. From this‚ we combined each metal complex with DMSO by refluxing the compound. The metal complexes were analyzed through their melting point and IR spectroscopy to determine whether the metal bonded to a Sulfur atom or an Oxygen atom of the DMSO. After analyzing the IR spectrum

    Figure 1. Average Mass Specific Surface Area for Three Fish. Error bars represent standard deviation from the mean. The graph represents the mass specific gill surface area for a sample size of 6 gill arches for each of the 4 lab sections (n=24). For Mackerel‚ the mass specific gill surface area was 13.62 cm2/kg. For Whiting‚ this value was 9.34 cm2/kg. Lastly‚ for flounder this value was 2.93 cm2/kg. Results: The three different species of fish‚ Mackerel‚ Whiting‚ and Flounder‚ have distinct

    Abstract The aim of my research was to study automatic processes by replicating the previously carried out Stroop effect. The participants‚ 20 Richmond College students (10 boys and 10 girls) chosen by an opportunistic sample were taken into a quiet room separately‚ were presented with 6 lists of words‚ out of which 3 were congruent and the other 3 incongruent and the time taken for each participant to name the colour that the words were written in was measured and recorded. From

    Table of results Surface area to volume ratio Time taken for HCL acid to diffuse (seconds) 14 38 9 90 7.3 139 6.5 178 6 185 3. Do your results support your hypothesis‚ use date from your table and graph to support your answer‚ you should also identify any anomalous results. My hypothesis was ‘as the surface-area-to-volume ratio decreases the diffusion rate increases’ my results support my hypothesis‚ because in my table of results when the surface area to volume ratio is at 14 the diffusion

    affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with the acid. This is because the acid only comes in contact with the particles on the surface of the donut. But‚ if you crush

    then determined that there were four ways to increase the reaction rate: increase temperature‚ add a catalyst‚ increase surface area‚ and increase the concentration of reactants. The objective of this lab was to experimentally show how temperature and surface area impact the rate of reaction‚ so only two of these methods were tested. The evidence indicates that increasing surface area increases the reaction rate‚ and increasing temperature also increases the reaction rate. Temperature is the measure

    The Stroop Effect Experiment In 1935‚ John Ridley Stroop conducted the original experiments of the stroop effect. The stroop effect is an effect that occurs when individuals attempt to name the color of words that spell out a conflicting color. Stroop reported an interference effect when individuals were asked to report the color of words presented to them. Stroop collected his data by showing his participants a sheet of paper with printed words on it. He then asked his participant’s to name the
