June 21‚ 2013 Title: Properties of Gases Purpose: To analyze a few physical and chemical properties of gases as well as using those properties to identify the gases. Procedure: * For Hydrogen I placed a piece of Zn metal into a test tube with diluted HCl. * To produce oxygen I added Hydrogen peroxide to manganese. * Next‚ I added baking soda to vinegar. This caused a quick and energetic reaction! The gas from the reaction I pumped into some Limewater. * Then I mixed Alka Seltzer

Effects of Enzyme Catalysis of H2O2 by Catalase Report by: Timmy Lin (#269164729) October 17‚ 2011 Mr. Rienzi AP Biology Problem: Measuring the effects of Catalase enzymes on hydrogen peroxide decomposition. Measuring the rate of the reaction when hydrogen peroxide and Catalase are mixed at the same ratio for different time (10‚ 20 30 60 120 180 360 seconds). Background: Enzymes are biological catalysts that carry out cellular metabolic processes with the ability to enhance the rate

your hands thoroughly with soap and water. 3. Put on the gloves. 4. Suction the tracheostomy tube. 5. Remove the inner cannula. 6. Insert the fenestrated cannula. 7. Hold the inner cannula over the basin and pour the hydrogen peroxide over and into it. Use as much hydrogen peroxide as you need to clean the inner cannula thoroughly. 8. Clean the inner cannula with pipe cleaners or a small brush. 9. Thoroughly rinse the inner cannula with normal saline‚ tap water or distilled water. 10. Dry the inside

This section analyzes and presents the results of the two trials conducted‚ including the trial in which Hydrogen peroxide(H2O2) was denatured by a cold catalase solution and the other in which the Hydrogen peroxide(H2O2) was denatured by a hot catalase solution. The experiment conducted displayed signs of experimental error as there were many situations in which the materials provided could have faulted. Theoretically speaking‚ from the inconsistent values provided for the pH levels‚ a possible

Hypothesis: I hypothesis that the enzyme concentration will affect the rate of reaction but only up until a certain point because there is a limited supply of substrate. Enzymes are protein molecule that acts as biological catalyst by increasing the rate of reactions without changing the overall process. They are long chain amino acids bound together by peptide bonds. Enzymes are seen in all living cells and controlling the metabolic processes in which they converted nutrients into energy and new

this lab students measured the height of the foam after catalysis between catalase (enzyme) and 7 other (solutions) to determine which solution had the fastest reaction rate.. The control variable of the experiment would be the solution of only hydrogen peroxide‚ water‚ and catalase. The independent variables of the experiment were the abiotic factors such as PH level‚ temperature‚ and the amount of salt within the environment. The dependent variable of the experiment would be the height of the foam(product)

INVESTIGATION INTO THE EFFECT OF TEMPERATURE ON CATALASE ACTIVITY AIM The aim of this experiment is to find out the effect of temperature on catalase or hydrogen peroxide. This will enable us to tell at what temperature hydrogen peroxide is most efficient. This (degradation) reaction will help us determine some of the catalase’s different attributes. HYPOTHESIS In this experiment it would be safe to hypothesise that no activity would take place at 1 to 20 degrees. It would be probable that a
