  • Methane-To-Methanol Reaction Report

    A. Defining Reaction Mechanisms and Catalyst Structure The methane-to-methanol reactions that we aimed to evaluate consist of four critical steps starting from the initial reactants (CH4, NH4+, oxo): C-H activation followed by a hydrogen atom abstraction (HAA) from CH4 to form some combination of the hydrogenated complex, ammonium or ammonia, and a methyl radical; a radical rebound (RR) to form a methanol adduct and ammonium; methanol dissociation from the metal; and catalysis regeneration via…

  • My First Chemistry Lab

    the cell that are more hydrophobic (water-fearing) and other parts that are hydrophilic (water-loving). The cell membrane is mostly hydrophobic and the cytosol is mostly hydrophilic. We made predictions of where the drugs would reach giving their chemical structure. This…

  • Protein Purification Practical Report

    Protein Purification Practical Report Student Name : Noel Murphy Date : 28 February 2015 UF/DF Practical Question Report Ultrafiltration (UF) and Diafiltration (DF) steps are carried out prior to every chromatography step and post the final polishing chromatography step. These UF and DF steps are vitally important, the UF step concentrates the protein product into a smaller volume of buffer, while the DF step alters the conditions the protein product is sitting in i.e. Buffer exchange.…

  • Enzymes Lab Report

    This enzyme also catalyzes the hydrolysis of a phosphate group connected to lipids in vivo or to proteins (Wilson et al., 2015). There are three major reasons that enzymes are important. The first reason is that enzymes speed up chemical reactions, and every chemical reaction…

  • Naoic Acid Reaction Lab Report

    Kinetic investigation and the Arrhenius plot The degradation of SAC in acidic, basic and oxidative mediums at different HCl (0.01, 0.05 and 0.1 M, keeping temperature 90 ºC), NaOH (0.005, 0.01 and 0.05 M, keeping temperature 40 ºC) and H2O2 (5%, 10% and 15%, keeping temperature 90 ºC) strengths was studied. Also SAC degradation was studied as a function of temperature in acidic (30, 60, 70, 90ºC and room temperature, keeping HCl strength 0.1M), basic (40, 65, 90ºC and room temperature, keeping…

  • Copper II Sulfate Lab Report

    Lab report Questions What will happen when zinc is placed in copper (II) sulfate? What will happen when copper is placed in copper (II) sulfate? Prediction It is predicted that when you place zinc and copper (II) sulfate a reaction will occur, resulting in a precipitation. The prediction about the copper (II) sulfate and copper is that nothing will happen. Hypothesis It is hypothesised that when zinc is placed in aqueous copper (II) sulfate, a single displacement reaction will occur as the…

  • Synthesis Of 3h From 2a-I Lab Report

    The synthesized molecules referred as E-and Z-isomers on the basis of NMR Spectroscopic data as reported. Conversion of E-isomer to Z-isomers take place by the process of photoisomerisation, chemical shift and differences between E-and Z-isomers in proton NMR spectral data was useful parameters for ascertaining to stereochemistry. All this synthesized molecules showed antioxidant activity using superoxide (NBT) and DPPH free radical scavenging…

  • Compare And Contrast The Reaction Between Bromine And Potassium Permanganate

    DISCUSSION There are three chemical properties will be discussed which are combustion, reaction with bromine and reaction with potassium permanganate. Combustion was used to test the unsaturation of hydrocarbon. The degree of unsaturation refers to the number of the rings and / or multiple bonds present in the hydrocarbon molecule (McMurry, 2015). Hexane was a saturated hydrocarbon, it completely combusted and emitted carbon dioxide plus water. Cyclohexene was an unsaturated hydrocarbon, it…
