Corrosion is the gradual destruction of materials (usually metals) by chemical reaction with its environment. In the most common use of the word‚ this means electrochemical oxidation of metals in reaction with an oxidant such as oxygen. Rusting‚ the formation of iron oxides‚ is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal. Corrosion can also occur in materials other than metals‚ such as ceramics or polymers‚ although

) The resulting solution is called an "electrolyte." Chemical Reaction When two dissimilar metals are put in an electrolyte‚ a chemical reaction called "oxidation-reduction" occurs. Because different metals have different levels of attraction for their electrons‚ one of the metals will lose electrons‚ a process which chemists call oxidation‚ and the other gains electrons‚ which is called reduction. The metal being oxidized is called the anode‚ and the one being reduced is the cathode. The entire

Name: Kristen Jackson Form: 35 Date: May 30‚ 2012 Geography Homework 1. Explain the difference in the process between carbonation and oxidation. When carbon dioxide in the air dissolves in rain‚ a weak carbonic acid is formed. This weak acid‚ while harmless to plants and animals‚ is able to dissolve some kinds of rocks‚ like feldspar and limestone‚ in a process called carbonation. Many caves begin forming during the process of carbonation. On the other hand‚ any mineral that reacts

Ludwig-Maximilians-Universita¨t Mu¨nchen‚ Munich‚ Germany . Introduction Under anaerobic conditions‚ in the dark and in the absence of electron acceptors‚ organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions‚ a process called fermentation. In fermentation‚ the organic compound serves as both electron donor and acceptor‚ and adenosine triphosphate is synthesized by substrate level phosphorylation. . Types of Fermentations . Distribution

this project is to create a game through which the user will be able to play a Sudoku puzzle. Our project deals with the task of designing a game of Sudoku using various algorithms. These are algorithms‚ both for generating games of various difficulties for the user and also for solving the puzzles provided by the user. A user will be able to ask for a random puzzle or the user will be able to manually input a puzzle. In either case‚ the software will be able to ask for a hint showing the next easiest

essential for our bodies. In the body these fatty acids are modified to make eicosanoids. These are the signaling molecules that have complex control over growth‚ inflammation‚ immunity‚ maintaining healthy skin‚ to name just a few. They are made by oxidation of twenty carbon chain fatty acids. The amount of these fatty acids in the diet will affect the body’s ability to make these eicosanoids‚ therefore having a direct effect on all of the functions the eicosanoids are responsible for‚ including growth

commercially available formalin has 10 to 12% methanol with a few impurities like aluminum and copper. Almost 21 million tonnes of formaldehyde is produced annually all around the world. Synthesis of Formaldehyde Formaldehyde is produced by catalytic oxidation of methanol. A mixture of molybdenum and iron or silver is used as a catalyst in such a reaction. But a more commonly used process is FORMAX. In this process‚ methanol and oxygen react at temperatures more than 250ºC in presence of vanadium to produce

Santo Tomas‚ Manila ABSTRACT The unknown hydrocarbon sample was differentiated and characterized by the use of three tests. The outcomes of these tests are as follows: Nitration test (negative)‚ Bromine test (positive) and Basic Oxidation test (positive). From these results the unknown sample can be classified as non-aromatic and unsaturated. INTRODUCTION Hydrocarbons are organic compounds that consist of only C and H atoms. They include the alkanes‚ alkenes‚ alkynes‚ and aromatic
