A Description of the Chemistry Experiment, Hydrogen Peroxide Decomposition
The catalysts available are: Manganese IV oxide (MnO2) Zinc oxide (ZnO) Lead IV oxide (PbO2) Aluminium oxide (Al2O3) Iron III oxide (Fe2O3) Copper II oxide (CuO) Copper III oxide (Cu2O) More specifically, it has been decided to investigate the change in time taken to fill a full test tube with oxygen in relat...
An Experiment: The Influence of Concentration of the Substrate Hydrogen on the Enzyme Catalase
INTRODUCTION The enzyme catalase speeds up the decomposition of Hydrogen Peroxide into water and oxygen as shown here, 2H2O2-------------------*2H2O O2. It is one of the fastest known enzymes and its turnover number is 6 million, which means the number of substrate molecules which one molecule of the enzyme turns to produ...
A Research on Hydrogen Peroxide (H2O2)
(H2O2), a colourless liquid usually produced as aqueous solutions of various strengths, used principally for bleaching cotton and other textiles and wood pulp, in the manufacture of other chemicals, as a rocket propellant, and for cosmetic and medicinal purposes. Solutions containing more than about 8 percent hydrogen perox...
The Use of Hydrogen Peroxide to Increase Crop Yields
For many years, farmers have been using hydrogen peroxide to increase crop yields. They suggest mixing five to sixteen ounces of 35% hydrogen peroxide with twenty gallons of water for every acre of land. Botanists suggest mixing one ounce of 3% hydrogen peroxide with a quart of water to improve the health of plants. (Jim’s)...
The Discovery and Usage of Hydrogen
Hydrogen fuel cells were invented by Sir William Robert Grove. However, they were not put to use until the 1960s when General Electric established workable proton-exchange membrane cells used as power supplies in the Apollo and Gemini space missions. Now, many years later, there is concern within the U.S. government over th...
A Description of the Several Ways of Packaging Hydrogen
Hydrogen can be "packaged" in several ways, as a fuel gas in a H2/02 powered engine or the newly devised solid state pellet of hydrogen isotopes that contains about the equivalent of 5000 cubic feet of hydrogen and is broken down and releases gas into the second chamber where it goes to the engine for use. There a...
The Potential Markets for Non-Fossil Fuel Hydrogen
ANALYSIS The Potential Markets For Non-Fossil Fuel Hydrogen · Hydrogen, most of it produced from fossil fuels, is already widely used in the chemicals industry, notably in the manufacture of fertilizers and petrochemicals. It would therefore be possible to substitute NFFH in this market. However, the total that could be...
An Analysis of Determining the Power of Hydrogen (pH) in a Given Substance
What is the pH of the substance? Controlled Comparison: During class, our instructor set up the same lab that we were doing with 2 solutions, both of which were known acidic or basic. He placed 2ml of the known acid into 2 different test tubes, and 2ml of the known acid into 2 different petri dishes. Then using forceps, he...
