PPT-LES REACTIONS DE COMBUSTION

11 Définition La combustion est une réaction chimique au cours de laquelle un combustible ou carburant est oxydé par un comburant généralement le dioxygène de lair avec un grand dégagement . DEFINITIONS AND TYPES. Revision:. DO NOT WRITE- FOR YOUR INFO ONLY. We have looked at the period table, what atoms are, elements and compounds. You have learnt that atoms can join to make compounds or molecules and that we can mix compounds to make new compounds…..these are chemical reactions. Fundamentals and Combustion Systems. Part I. Chemical Equilibrium. Chemical . Kinetics. Fuels. Part II. Flames. Gas-Fired furnace combustion. Premixed-charge engine combustion. Part III. Spray formation and droplet size. Physical Properties of Alkanes. Non polar compounds. Insoluble in water. Less dense than water and so will float on top of the water. Dissolve in organic solvents . . (. eg. dry cleaning fluid) and in each other (. WILLIAM h. . gREEN. .  . Co-Authors:. . Shamel . S. Merchant. 1. , Aaron G. Vandeputte. 1. , Connie W. Gao. 1. , Nick M. Vandewiele. 1,2. , Nathan W. Yee. 1. , Marko R. Djokic. 2. , Kevin M. Van Geem. Hydrocarbon ignited in a condition of excess oxygen will combust (oxidize). Forms carbon dioxide, energy and water. Combustion is an exothermic reaction (so the net reaction involves the net output of heat energy). Oxidation Reactions. Exothermic vs Endothermic. Exothermic. Endothermic. A chemical reaction that gives off energy.. The reactants have more energy than is needed to form the products so they release it.. Lecture slides by. Mehmet . Kanoglu.

It always produces carbon dioxide and water vapor.. Example:. CH. 4. + 2 O. 2. .  CO. 2. + 2 H. 2. O. Many times the compound also contains oxygen. Example:. 2C. 3. H. 4. O. 3. +. . 4. Redox Reactions. Oxidation-Reduction (Redox) Reactions. Redox reactions involve an electron transfer.. These reaction occur between metals and nonmetals.. Ionic reactions are redox reactions.. The name. . In a combustion reaction, a candle burns using the oxygen in the air.. Learning Goal . Identify . a reaction as a combination,. decomposition, single replacement, double replacement. , or . combustion.
