enzyme normally found in many plant and animal tissues. Its purpose is to destroy toxic substances which may be introduced into cells. Also‚ some cells use catalase to destroy cellular debris or worn out organelles. In this lab‚ we will use a catalase solution from potatoes and determine the effect of temperature and pH on the action of this enzyme. The substrate of the enzyme will be 3% hydrogen peroxide (H2O2). Catalase works by the following mechanism: 2 H2O2 ------------------>____2 H2O+ O2 Materials:

Copper vs Fiber They are two major types of cables used in networking‚ copper and fiber. Each cable are used in different application regarding to its usage. They also have different strengths cause of the material they are made of. Copper is the most common out of the two cables. Not as powerful as Fiber‚ but are ideal for buildings up to 100m. Fiber is mostly used for longer distances that copper can’t reach. For example‚ Fiber is ideal for high-rise buildings. Both cables do have their weakness

When trying to decide between copper and fiber cabling‚ there are several things to think about for which one best will fit your needs. A few things you will need to take into consideration when making your decision are what do you need your cable to be capable of‚ how far do you need your cable to run from point to point‚ what is your budget‚ and always think about the future with room to expand your business. Both copper and fiber cabling have pros and cons. Copper cabling has been around ever

Purpose Determine which kinds of reactions involve electron transfer as the driving force. Background Redox (reduction-oxidation) reactions include all chemical reactions in which atoms have their oxidation state changed. So‚ when a metal and a nonmetal react‚ there is an ionic bond formed‚ which means one of them loses electrons while the other gains them. Since this reaction involves the exchange of electrons it is termed as a redox reaction. The oxidation states in a metal- nonmetal are simple

The Stock Market Reaction to Oil Price Changes Sridhar Gogineni Division of Finance Michael F. Price College of Business University of Oklahoma Norman‚ OK 73019-0450 March 13‚ 2008 Abstract I explore the reaction of the stock market as a whole and of different industries to daily oil price changes. I find that the direction and magnitude of the market‟s reaction to oil price changes depend on the magnitude of the price changes. Oil price changes most likely caused by supply shocks have a

DETERMINATION OF THE THICKNESS OF ZINC ON A PIECE OF GALVANIZED METAL Department of Biology‚ College of Science‚ University of the Philippines Baguio ABSTRACT The experiment was performed to be able to determine the thickness of zinc on a piece of galvanized metal. It also aimed for the students to be introduced to the reactivates of metals with acids as well as for them to develop some feeling for the size of an atom. In determining the thickness of the zinc coating on the metal‚ students

Redox reactions (Redox terminology‚ galvanic cells‚ standard electrode potentials‚ strength of oxidizing/reducing agents‚ corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents‚ such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions

Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6.36 grams of
