Chemical decomposition

Interpretation 1. Theoretical Lab Discussion This lab occurs due to enzyme kinetics, and the kinetics molecular theory. Enzyme kinetics is the study of chemical reactions that are catalysed by enzymes, and during the experiments, the reaction rate was measured by the effects of the varying conditions the substrate was in. Influence of Catalase Concentration The higher the concentration of the enzyme catalase, the function of the enzyme occurs better. As the number of disks increased, the…

1. Which one of the following would make the most suitable catalyst in the decomposition of hydrogen peroxide (H2O2)? A. Carbon dioxide (CO2) B. Sodium chloride (NaCl) C. Magnesium oxide (MgO) D. Manganese dioxide (MnO2) 2. If the temperature of a reaction is decreased, what effect will this have on the rate of reaction? A. It will have no effect. B. The reaction will stop. C. The rate of reaction will increase. D. The rate of reaction will decrease. 3. Given the equilibrium reaction in a closed…

Analysis Questions: 1. The primary reaction catalyzed by catalase is the decomposition of hydrogen peroxide to form water and oxygen, which occurs spontaneously, but not at a very rapid rate. Write a balanced equation for this reaction. Label the reactant and the product. (Remember that catalase is not a reactant or a product and can be written over the arrow separating the reactant from the products.) I will help you with the equation. Catalase 2H2O2…

Introduction Desulphurization of steel at ladle treatment of metal is one of the important technological operations. The successful course of the desulfurization process is provided by fire refining slag with specific chemical composition, usually based on calcium oxide. The duration of mixing of the metal with the slag in inert gas, the early formation of refining slag, then optimization of the metal oxidation providing the formation of iron oxide FeO in the slag to be less than 0.5 % able…

a priority when conducting labs. Especially when handling chemicals, the ideal setup of labs should avoid any obstructions and potential hazards that may occur. This is due to the possible dangers: flammable and combustible chemicals (alcohol, sodium), oxidation (hair dye), bio hazardous products (which causes AIDS, rabies), toxic items (lead, benzene), poison (carbon monoxide), corrosive compounds (bleach), dangerously reactive chemicals (fluorine) and compressed gas (propane, CO2). Regarding…

intake can result in the disruption of human metabolism, and how it can degenerate the biological well being of ecosystems. The experiment was performed in order to demonstrate that a specific amount of copper could undergo a series of different chemical reactions, and in the end revert back to its original solid state and quantity. A percent yield was calculated at the end of the experiment to display the amount of copper that was lost or gained after the series of reactions had taken place.…

The objective of Chapter 6: Compounds and Elements was to determine how to synthesize and decompose pure substances, distinguish the difference between compounds and elements, and to determine the difference between complete and incomplete reactions. Previous chapters that contained valuable background knowledge were Chapter 2: Mass Changes in Closed Systems and Chapter 5: The Separation of Mixtures. The Law of Conservation of Mass, which was tested in Chapter 2, proved to be vital in this…

the material Scheme 1. Substitution of 3-(m-tolyl)propan-1-ol to form 1-(3-bromopropyl )-3-methylbenzene. Aromatic materials used in this reaction has high boiling point thus the reaction was heated carefully and gently to avoid burning and decomposition of other reagents. Byproduct such as E2 elimination seen often with good leaving groups and basic nucleophiles or rearranged products, expected with alternative mechanism were unable to observed by gas chromatography or H NMR. The initial…

Weakness Explanation Suggestion(s) for improvement Not measuring the temperature of the liver cubes that are the sources of the enzyme catalase. Although the hydrogen peroxide solutions were at the desired temperatures, it was uncertain whether their paired liver cubes had the same temperatures. This places concern on whether the froth height was close to being accurate, hence reliable. If the temperature of a liver were lower than the desired temperature, the enzymes would be less likely to…

This is shown in the balanced chemical equation by the products of water and the solid copper chloride. The observation of the liquid turning clear represents the water and seeing the particles represents the precipitate. The yield of copper chloride is 1.49 grams. This demonstrates the…
