    conducted involved a process called the Maillard Reaction. When it comes to cooking meats, heating the food causes the proteins, especially those nearest the surface of the meat, to denature. These denatured proteins become more chemically reactive to other molecules in their environment. One of the primary reactions that occur when browning meats and many other foods is called the Maillard Reaction. The Maillard Reaction is a non-enzymatic chemical reaction between amino acids and reducing…

    replaced by halogens, they become an alkyl halide compound which can also be called haloalkanes. There are two types of reaction within the alkyl halides. When another atom replaces the halide ion, the reaction becomes a substitution reaction, and when the halide ion leaves with another atom or ion, it becomes an elimination reaction (Weldegirma, 2015). The substitution reaction can be divided into either electrophilic substitution or nucleophilic substitution. In the nucleophilic substitution,…

    In this experiment, a Wittig reaction was performed in order to synthesize a mixtures of (E)- and (Z)-stilbene. Photoisomerization was then performed to isolate (E)-stilbene by transforming (Z)-stilbene into (E)-stilbene. The presence of the products throughout the experiment was monitored by 1H NMR. The final product was then characterized by 1H NMR, IR and its melting point. During synthesize of the product, the appearance of the reaction mixture changed. The main solution…

    In our experiment, to look deeper into exothermic reactions, we first had to create our own calorimeter. We did this using 3 separate 8 ounce Styrofoam cups, one for each compound. We then used cardboard to create a lid for each cup and taped it to the sides so the seal would be as tight as we could make it. We also needed a 150mL beaker to measure out the 50 mL of distilled water that we used in each trial to dissolve each compound in. To weigh out each compound we also needed an electronic…

    Aqueous-Minerals Reactions: Chemical reactions involving aqueous species and mineral species are heterogeneous and slower compared to aqueous species reactions, thus modeled as rate dependent chemical reactions. This means that when mineral species (N_m ) are not is equilibrium with the aqueous species, the minerals can either dissolve or precipitate. As shown in equation R11 of an example of calcite dissolution/precipitation, a mineral species (Calcite) is involved in a reaction with only…

    Scenario 1 describes the reaction that takes place between H2 and I2 to form the acid HI. This reaction involves very intricate and steps that are critical to understanding the concept of equilibrium as a whole. First, an important concept to understand when describing any reaction is the idea of collision probability. When we examine gas molecules in a 1 cm3 container, there can be billions of collisions per second between neighboring molecules, and even then, maybe only one of these collisions…

    Scheme 3. Substrate scope of the Mannich reaction of 5 to α-amido sulfone 3. Reactions were performed with 5 (0.1 mmol), 3 (0.12 mmol), KF (0.3 mmol), and (R)-1b (10 mol%) in o-xylene (1.5 mL) at 25 °C. The yield was determined after chromatographic purification, and the ee value was determined by HPLC analysis using a chiral stationary phase. Diastereomeric ratio was determined by 1H NMR. To demonstrate the scalability of the process and the application potential of the resulting chiral Mannich…

    rate of reactions are affected by volume affects and determine which chemical affects the solution rate of reaction. Temperature was also a factor in discovering how it will affect the speed of the reaction. This was done by gathering certain chemicals and mixing them into a test tube then recording how long it took to change color. Temperature was tested by placing the test tube in ice water over a hot plate and slowlying increasing the temperature. Sodium thiosulfate slows the rate of reaction…

    The chemical reaction can be dangerous I used the, A: soap and bleach and B: soap and water. The reaction in A as the week pass the soap starts to get smaller and smaller, on the left and the right it got white a little. The chemical reaction on A is that the bleach got clear and light at the soap that have been use in the experiment. In Bowl B the water and soap that have been used in the experiment was breaking up, getting lighter. In bowl B the soap took away the walker as the week have…

    This report gives an information which is related to the reaction between acidified potassium iodide and hydrogen peroxide. Before calculating the rate of this reaction, the reaction will be carried out 3 times and values will be got. A special timer will be used to measure the time. It could be expected and argued that each time will be able differ from the others in each reaction and it can be explained by changing the quantity of hydrogen peroxide. At the final, it will be obviously observed…
