1. Combustion reaction By: Valeria Younan http://s2.hubimg.com/u/743005_f260.jpg

2. Types of chemical reactions Combustion Synthesis Decomposition Single displacement Double displacement Acid-base http://misterguch.brinkster.net/6typesofchemicalrxn.html http://www.buzzle.com/img/articleImages/51510-36.jpg 6 types of chemical reactions Chemical reactions

3. What is a combustion reaction? A combustion is a chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. http://en.wikipedia.org/wiki/Combustion Combustion reaction Combustion reaction http://media-2.web.britannica.com/eb-media/63/124363-004-81232F4C.jpg

4. What is the fire triangle? The triangle illustrates a fire requires three elements: heat, fuel, and an oxidizing agent which is usually oxygen in many cases. http://en.wikipedia.org/wiki/Fire_triangle http://www.valleylabeducation.org/fire/images/triangle.gif The fire triangle The fire triangle

5. What is activation energy? It’s the energy that an atomic system must acquire before a process can occur. http://www.google.com/search?hl=en&defl=en&q=define:activation+energy&ei=TM5tS-2rJYjUM7KDyNUE&sa=X&oi=glossary_definition&ct=title&ved=0CAcQkAE http://www.columbia.edu/cu/biology/courses/c2005/purves6/figure06-14.jpg Activation energy activation energy

6. Why is heat/energy a necessary part of the triangle? http://www.fitsafe.com.au/images/p-fire_triangle.gif Heat is a necessary part of the triangle because without heat, the fire can not begin nor cant it continue. http://en.wikipedia.org/wiki/Fire_triangle Heat is a necessary part of the triangle Heat is a necessary part of the triangle

7. How is the cook top of the stove, a real life example of the fire triangle? The stove is a real life example of the fire triangle because the stove needs heat, fuel, and oxygen in order for it to work. http://www.kitchen-ranges.com/kr_how-range-stove-work.html http://www.tilebydesign.net/kitchen3.jpg Cook top of stove; real life example Cook top of stove; real life example

8. What is a combustion engine? It is the engine in which the combustion of a fuel occurs with an oxidizer. http://www.google.com/search?hl=en&defl=en&q=define:Combustion+Engine&ei=pdZtS-rnDJTYNtmK6dIE&sa=X&oi=glossary_definition&ct=title&ved=0CAcQkAE http://bkachinsky.transworld.net/files/2009/06/internal-combustion-engine1.jpeg Combustion engine Combustion engine

9. How does a combustion work? A fuel such as gasoline fills the chamber and then it is ignited by a spark plug. http://www.wisegeek.com/how-does-an-internal-combustion-engine-work.htm http://media-2.web.britannica.com/eb-media/72/93572-034-26C16785.jpg The combustion The combustion

10. How are NASCAR engines different from street engines that allow them to operate at much higher speeds? The displacement of NASCARS is large 358 cubic inches. Not many cars have engines this big, but the ones that do usually generate well over 300 horsepower. They have high intensity programmable ignition systems so the spark timing can be customized to provide the most possible power. http://auto.howstuffworks.com/question588.htm http://images.machinedesign.com/images/archive/2ndgenerationsm_00000037517.jpg http://images.businessweek.com/ss/07/03/0312_wikiguide/image/4-nascar.jpg NASCAR engines NASCAR engines

11. How does oxide help engines perform better? Nitrous oxide improves performance even more. When it vaporizes, nitrous oxide provides a significant cooling effect on the intake air. When you heat nitrous oxide to about 570 degrees F (~300 C), it splits into oxygen and nitrogen. So the injection of nitrous oxide into an engine means that more oxygen is available during combustion. Because you have more oxygen, you can also inject more fuel, allowing the same engine to produce more power. http://auto.howstuffworks.com/question259.htm http://www.holley.com/data/products/pictures/large02119NOS.jpg Oxide helping engines Oxide helping engines

12. Glenn Dunnaway http://static.howstuffworks.com/gif/1993-nascar-results-1.jpg Glenn Dunnaway won the race by three laps. But in further inspection, but it turned out the rear springs on the Ford were an improver. Dunnaway was disqualified form the race and Jim Roper was declared the winner instead. http://legacy.signonsandiego.com/uniontrib/20060225/news_1s25fontana.html More information pictures
