Prac 18 – Reaction Rate of Notongooglenium – Angus Dally Research Question: How does the presence of a Notongooglenium oxide catalyst effect the rate of hydrogenation of ethenol (vinyl alcohol)? Aim The aim of this experiment is to find the effect of the manganese oxide catalyst, a similar compound to Notongooglenium Oxide, on the rate of hydrogenation of ethenol (vinyl alcohol). Introduction Notongooglenium Notongooglenium is a newly discovered element with an atomic number of 24.5. Due to its…

III. RESULTS AND DISCUSSIONS: A. Characteristics of Aluminum-Graphite composites and the in-situ reaction To examine the reaction condition of carbon flakes and Al powders, 4 wt. % carbon flakes were added to Al powders. Fig. 1 shows the DSC plot obtained during heating and cooling of the green compact from room temperature to 750 0C and from 750 0C to room temperature at a heating/cooling rate of 3 0C /min under argon gas atmosphere. From the DSC heating curve it is evident that the total…

breasts, potatoes, and apples. We also used hydrogen peroxide, warm and cold, acidic and basic, and used liquid from a reaction. Hydrogen peroxide acts as a substrate for the enzymes. The reactants were the catalyst of different tissues and the variations of hydrogen peroxide. When combined, the product was water, oxygen, and any dead cells left in the liquid due to the reaction. In trial 1, we used liver and hydrogen peroxide. This was our control trial.…

Hello I am Marcus Gonzalez a chemistry student at Texas State University and my lab partner, Colten and I where instructed to see if the combination and specific concentrations of sodium thiosulfate plus sodium hypochlorite are able to produce second degree burns on a person within 10 seconds. In order for a second degree burn to be possible we must reach a temperature of at least 56°C (133°F) in order to create burns up to third degree for the time the chemical stayed on the worker. Now the…

of an invaluable chemical reaction (The Nobel Prize in Chemistry 1950). The reaction they described was for the formation of carbon-carbon bonds in a six membered ring with exceptional control of its stereochemistry in one step (Diels-Alder Reaction Gains Nobel Prize). This was an important discovery due to the fact that six membered rings are abundant natural products and man-made products. Several new compounds were synthesized as a result of the Diels-Alder reaction including: Reserpine,…

With the knowledge of single displacement reactions, it is common to assume that there will always be a reaction between chemicals that present the opportunity of (metalA) + (metalB + nonmetal) → (metalB + nonmetal) + (metalA). In this lab, this notion will be discarded as the activity series demonstrates the actual nature of single displacement reactions where the metals will only exchange if their activity series levels allow them to do so. To explain…

functionality, where n is number of equivalents of glycidol reacted with carbazole. Carbazole reacts with glycidol without catalyst. The process is exothermic and thus needs control of temperature. Reaction of carbazole with glycidol requires excess of glycidol, the best molar ratio is 1:7. When lower excess of glycidol is used, the carbazole precipitates from reaction mixture. This semiproduct obtained from carbazole and…

standards (1 Br, 2 Br) in order to determine if Markovnikov’s rule is followed. In general, Alkenes are able to undergo addition reactions due to the strength of their C-C -bond (60-65 kcal/mol) which is lower than the strength of a typical -bond (80-100 kcal/mol) between Carbon and other atoms. Adding a reagent across the double bond results in an exothermic reaction because one -bond is replaced by two higher energy -bonds. Accordingly, the addition of HBr(aq) to 1-Hexene involves the…

of Minnesota Abstract The purpose of this experiment was to evaluate magnesium chloride as a deicer. To be a good deicer, a salt must be able to lower the enthalpy when is mixed with water. This will cause an exothermic reaction and release heat. This experiment had three tests performed within it, The freezing point depression, the enthalpy of dissolution, and finding the calorimeter constant. Even though, the results in this lab had a high present of error it…

Plus has been used as the primary modelling tool. The main advantage of using Aspen Plus is that it dramatically reduces the time required for compilation and critical evaluation of properties of reaction components which underlie difficulties in process model development. As a whole, kinetics and reaction mechanisms for autothermal reforming of bio-oil or its constituents are scarce. Hence, to get started with the modelling work, methane, which is the simplest hydrocarbon, was chosen as the…
