The document discusses different types of chemical reactions such as combustion, synthesis, and decomposition. It then explains concepts related to combustion such as the fire triangle, activation energy, and heat energy. Specific examples of combustion engines are provided, including cooktop stoves, internal combustion engines, and NASCAR car engines. Nitrous oxide is described as increasing the oxygen available for combustion when injected into an engine. A brief history of nitrous oxide use and cheating in NASCAR is also mentioned.
2. Different type of chemical reaction Combustions Synthesis Decomposition Single displacement Double displacement Acid base
3. The fire triangle Is a simple model for understanding the ingredients necessary for most fires. http://en.wikipedia.org/wiki/Fire_triangle
4. Activation energy is a term introduced in 1889 by the Swedish scientist Svante Arrhenius, that is defined as the energy that must be overcome in order for a chemical reaction to occur.
5. Heat energy Its important because its raises the material of to its ignition temperature without sufficient energy. http://physics.about.com/od/glossary/g/heat.htm
6. Cooktop stove When the gas from gas tank comes out to the outside of the cook top then it connects energy to make a fire. http://www.pickyourown.org/productpics/img8D.jpg
7. Combustion engine Is an engine in which the combustion of a fuel (generally, fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber
8. Combustion engine works The principle behind any reciprocating internal combustion engine: If you put a tiny amount of high-energy fuel (like gasoline) in a small, enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gas. http://auto.howstuffworks.com/engine1.htm
9. Nascar car Dodge provides the engine block and cylinder head for the engine. They are based on a 340 cubic inch V-8 engine design that was produced in the 1960s. The actual engine blocks and heads are not made from the original tooling, they are custom made race engine blocks, but they do have some things in common with the original engines. http://auto.howstuffworks.com/question588.htm
10. Nitrous oxide It turns out that nitrous oxide (N20) works exactly the same way. 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. http://auto.howstuffworks.com/question259.htm
11. Cheating on nascar In this country during 1950s the famed stock car racer Smokey Yunickrediscoverd nitrous oxide injection as one of his many schemes for winning races until discovered and outlawed by NASCAR. Neverthesless, there have been several nitrous oxide cheating scandals in NASCAR over the years and it is probably still used today by the slowest of backmarkers. In the late-70s/early-80s nitrous oxide was "rediscovered" by drag racers and hot rodders. http://www.idavette.net/hib/nitrous.htm
