An investigation to compare the reaction rates between potato and hydrogen peroxide against liver and hydrogen peroxide through loss in mass. Background information: Catalase is an enzyme that is found in all cells. This means that it is an intracellular enzyme. And enzyme is a biological catalyst. A catalyst is some thing that speeds up a reaction without being changed itself. Because of this enzymes and catalysts can be used again and again. Enzymes are protein chains that have a primary‚ secondary

re-fuel‚ launch‚ educate and distribute?) Benefits. No pollution: A great benefit of using Hydrogen fuel cells is that they give off no pollution‚ and in fact produce pure water as a byproduct. Even though currently engineers are concentrating on producing hydrogen from natural gas‚ it will be for a short-term. Scientists are planning to have renewable environmentally-friendly ways of producing hydrogen in the future. Efficiency: Fuel cells generate electrical power quietly and efficiently. Approximate

Biology investigation: Liver and hydrogen peroxide By Cuong Tran Abstract: The purpose of this investigation was to determine the optimum temperature for enzyme activity. The stated hypothesis was that 37oC would be the optimum temperature for liver enzymes to break down hydrogen peroxide into water and oxygen. The dependent variable was to measure the amount of foam being produced‚ while testing 4 different temperatures with 3 repetitions each. Out of the 12 trials only 2 outliers were found

relation to this dilemma. Past research has shown that hydrogen fuel cells can quite possibly replace the country’s current usage of oil while having a more positive effect on the environment. However‚ environmentalists have conducted their own contradicting research on fuel cells reflecting negative effects on the environment. Numerous articles have been published which express both sides of this debate. Although some scientists believe hydrogen fuel cells will improve the environment and rid the United

Hydrogen Fuel Cell Cars: Worth the Investment? Hydrogen is the most abundant element in the universe‚ but only recently have people been able to harness this resource and turn it into energy. Hydrogen fuel cell cars are one such advancement made in the effort to turn hydrogen gas into electricity. Fuel cells in the car are used to convert hydrogen into an electrical current‚ and thus power the vehicle. Fuel cells convert hydrogen and oxygen into water while producing electricity. Hydrogen fuel

Decomposition of Hydrogen Peroxide by Potassium Iodide Brief Description: Two solutions are mixed resulting in an eruption of foam resembling a huge stream of toothpaste. This is the classic “Elephant Toothpaste” reaction. Purpose/Goal: Procedure presents an example of a catalyzed reaction. Explanation of Experiment: The rapid evolution of oxygen gas is produced by the following reaction: 2 H2O2 (aq) = 2 H2O (l) + O2 (g) + heat The decomposition of hydrogen peroxide in the presence
