The Effects the Decomposition of Hydrogen Peroxide An investigation into how the amount of oxygen is produced by changing one variable effects the decomposition of Hydrogen Peroxide in the presence of the enzyme. This shows us that when the H2O2 has reacted with the catalyst this is what it produces. There are many ways in which the amount of oxygen produced could be affected. I believe that, surface area of the chip, temperature of liquid that is reacting, the concentration of the liquid…

Hydrogen Cyanide Hydrogen Cyanide (HCN) is an extremely poisonous liquid discovered in 1782 by Carl Scheele, a Swedish chemist. HCN is very toxic because it stops cells from using oxygen properly thus causing death. Although HCN is a great solvent for salts, it cannot be used due to its high toxicity. Even though it is general stable, it has the capacity to combust in the company of basic substances such as ammonia or sodium cyanide. What is its structure? The structure of Hydrogen cyanide is…

Hydrogen energy and fuel cells in general will require a lot of research and development to be used at a large scale so more engineers and chemists will be demanded for. Electrical, chemical, and industrial engineers would have a whole new field to study and to specialize. This means that there would be more job opportunities to those who specialize in working with hydrogen energy and fuel cells. These engineers would have to learn how to control hydrogen to find its maximum potential…

CO2 Balanced – C5H12 + 8 O2 = 6 H2O + 5 CO2 (5 points) Score 2. Methane (CH4), ammonia (NH3), and oxygen (O2) can react to form hydrogen cyanide (HCN) and water according to this equation: CH4 + NH3 + O2  HCN + H2O…

For reactions with a medium, or “one to one”, ratio of iron (II) to hydrogen peroxide, the generation of hydroxyl radicals is also observed. In this particular ratio, the presence of organics does not seem to inhibit the effectiveness of the iron catalyst, as all the iron (II) was converted to iron (III) in a series of experiments. Without the organics present, the hydrogen peroxide reformed by reacting slowly with iron (III) to produce ferric salts, which then degrade into more hydroxyl…

NAME: Serina Alashi DATE: TITLE: Decomposition reaction: hydrogen peroxide (H2O2) decomposed into hydrogen and oxygen ( H2 and O2) RESEARCH QUESTION: How will changing the concentration of hydrogen peroxide affect the rate of reaction, that is represented by the increase in pressure over time? Introduction: Hydrogen peroxide is a chemical compound of hydrogen and oxygen. It is a very strong oxidant but weak in water solution. Hydrogen peroxide decomposes into water and oxygen when heated…

Hydrogen Peroxide Decomposition Lab Report Objective: By utilising the catalyst of potassium iodide to trigger a decomposition reaction in hydrogen peroxide, how will fluctuation in temperatures will affect the decomposition rate? Hypothesis: Due to the decomposition effect of potassium iodide on hydrogen peroxide, the increased temperature applied will also increase the decomposition rate, because of the more occurrences of collisions which causes the more energy to be produced. Independent…

Rough Draft Does Hydrogen Peroxide Help or Harm Seeds? Hydrogen peroxide (H2O2) is a common household item. It is made of two hydrogen atoms and two oxygen atoms. It is most commonly used in small concentrations to clean small cuts and scrapes by killing bacteria. This antiseptic kills the bacteria by tearing down their cell walls. In the last few years, hydrogen peroxide has been added to pesticides. This means that the food we consume has been growing in materials that contain hydrogen…

two test tubes are clearly labeled with 1 and 7, test tube 1 contains the 1 cm³ liver and test tube 7 contains the 5 mL of hydrogen peroxide. these two test tubes are in a 250 mL beaker containing approximately 125 mL of tap water and ice. The thermometer was placed in test tube 7, which contains the hydrogen peroxide to measure the temperature of the solutions. The hydrogen peroxide was poured into the test tube containing to the liver and was observed. Figure 2: Diagram of the apparatus…

Peroxisomes serve to produce hydrogen peroxide through oxidation, as well as break it down by converting it to water, or using the hydrogen peroxide to oxidize other organic compounds. They also produce energy by metabolizing fatty acids (Cooper, 2000). Peroxisomes execute various metabolic functions and create hydrogen peroxide as a byproduct from the process of oxidation. However, since the hydrogen peroxide created by the peroxisome is toxic, the organelle also produces an enzyme called…
