9. Acid-baseWhat are the different types of chemical reactions? http://en.wikipedia.org/wiki/Chemical_reaction http://static.howstuffworks.com/gif/science-projects-for-kids-chemical-reaction-3.jpg
10. What is combustion reaction? A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic, meaning they produce heat. http://misterguch.brinkster.net/6typesofchemicalrxn.html http://t3.gstatic.com/images?q=tbn:qMg3xWWM42oY6M:http://www.colourlovers.com/uploads/2008/09/209662750_826d454af2.jpg
11. What is the fire triangle? Fire triangle is a simple model for understanding the ingredients necessary for most fires. http://en.wikipedia.org/wiki/Fire_triangle http://t1.gstatic.com/images?q=tbn:slgZRwRQ9eNbrM:http://z.about.com/d/forestry/1/5/m/G/byw_fire2.jpg
12. What is activation energy? Activation energy is the minimum energy required to start a chemical reaction. http://en.wikipedia.org/wiki/Activation_energy http://www.biologyjunction.com/images/activationenergy1.gif
13. Why is heat/energy a necessary part of the fire triangle? Without heat, a fire cannot begin, and it also cannot continue. http://t3.gstatic.com/images?q=tbn:0lDvbkzXzzq_0M:http://www.tswca.org/images/triangle_heat.gif http://en.wikipedia.org/wiki/Fire_triangle
14. How is the cook top of your stove (not electric) a real-life of a fire triangle? The cook top of your stove needs air, fuel, and heat in order to make a fire. http://www.smartmarine.co.nz/images/large/kramer%20stove.jpg http://en.wikipedia.org/wiki/Fire_classes

16. The internal 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. http://img.directindustry.com/images_di/photo-g/internal-combustion-engine-27659.jpg http://en.wikipedia.org/wiki/Combustion_engine
17. (in general) How is combustion engine work? With an internal combustion engine, fuel is burned inside the engine in what is known as a combustion chamber. The combustion chamber is an enclosed space where the gasoline goes. Once the gas of the confined gasoline expands, it produces energy. http://www.techchee.com/wp-content/uploads/2009/10/How-to-build-a-combustion-engine-using-model-making-kit-450x334.jpg http://www.dmv.org/how-to-guides/combustion-engines.php
18. In term of combustion, how are NASCAR engines different from street car engines that allow them to operate at much higher speed? 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
19. How does nitrous oxide help engines perform better? 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://2fastlane.com/blog/wp-content/uploads/2006/11/nos3.jpg http://auto.howstuffworks.com/question259.htm
20. One documented example of cheating in NASCAR in which something was done illegally to increased the combustion performance of the engine. The news of Michael Waltrip cheating in NASCAR. The officials found illegal additives had been mixed in the fuel of his car All the crews try to do something with the car to increase its performance and are involved in some degree of cheating and they know that the maximum penalty is a fine and lose of points so they just try and go that extra mile hoping that they don’t get caught. http://cache.jalopnik.com/cars/assets/resources/2007/02/73321814.jpg http://www.moto-crossing.net/Nascar-Information/Nascar-Cheating.html
