Introduction: Biological organisms are classified uniformly in order to easily categorize and identify organisms. This classification‚ or taxonomy‚ uses the genus name followed by the species name‚ in Latin. By having a universal method of identifying bacteria allows for all scientists from any part of the world to identify the same species in an identical manner allowing for a precise of classification. Bacteria are distributed throughout the world in almost every conceivable habit. Bacteria are

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

Condition‚ if any‚ is written generally above the arrow. When hydrogen reacts with oxygen‚ it gives water. This reaction can be represented by following chemical equation. In first equation words are used and in second symbols of substances are used to write the chemical equation. For convenience‚ symbol of substance

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

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

the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially harmful oxidizing agent‚ to
