Explanation Oxidation is the process whereby reactant loses one more electrons Reduction is the process whereby reactant gains one more electrons Oxidation and reduction are simultaneous process and is called redox Reaction Metals have a natural tendency to revert back to combined state and which leads to the formation of oxides. The process by which the Metals have a natural tendency to revert back to combined state is called corrosion Corrosion is a process by which the metals are destructed or decayed by the electrochemical or chemical reaction with environment Through corrosion, properties of metals are weakened Deterioration of a chemical substance by the action of environment- Corrosion Combustion is an exothermic reaction in which a rapid oxidation-reduction is occurred Combustion of fuel produces huge amount of energy Metals have a natural tendency to revert back to combined state and which leads to the formation of oxides. The process by which the Metals have a natural tendency to revert back to combined state is called corrosion. Corrosion is a process by which the metals are destructed or decayed by the electrochemical or chemical reaction with environment. The environment could be of any type such as atmosphere, water, seas water. Acids, alkalies, steam, gases, liquid metals etc. and the interaction of metal wit this environment could take place at any temperature. Through corrosion, properties of metals are weakened. Corrosion is slow process. Corrosion can be prevent by adopting certain methods. One of the method is galvanization. Process of coating the certain metals with a thin layer of zinc for protecting from corrosion is called galvanization. Galvanization is the process through which irons or steel are protected from rusting. In the galvanization, a protective zinc coatings are applied. Zinc oxidizes faster than iron and it oxidized to zinc oxide which is insoluble and inert. These insoluble inert substance protect the iron underneath it from rusting. The second method is cathiodic protection by placing the iron or corroding metal with metals. Combustion is an exothermic, rapid oxidation reduction reaction. Burning of campfire is an example of combustion. Rate of combustion is rapid on comparing to the rate of corrosion. Combustion of fuel produces huge amount of energy. Combustion of carbon containing material such as wood and fossil fuels forms carbon dioxide...
