Different types of chemical reactions

There are 6 types of chemical reactions1. Combustion2. Synthesis3. Decomposition4. Single displacement5. Double displacement6. Acid-Basehttp://misterguch.brinkster.net/6typesofchemicalrxn.html http://www.cdschools.org/54227011714634/lib/54227011714634/chemical_reactions.jpg

Combustion Reaction

• Burning of Complex sequence of exothermic chemical reactions between a fuel.

Fire Triangle

The fire triangle is mainly the three main things oxygen heat and fuel.

Activation Energy

The energy that should be acquired before a process can occur.

Why is heat a necessary part of the fire triangle

Without energy in the form of heat the fire cannot heat unburnt fuels.

Cook top of your stove

The cook top of your stove is an example because we need heat and fuel to cook food.

How does a combustion engine work?

The air enters the engine and helps it work faster and better.

NASCAR engines and street car engines

The engines are of a better quality and can be used for a longer period of time. While street car engines can take in only a certain amount of time.

Nitrous Oxide

Nitrous oxide has another effect that improves performance even more. When it vaporizes, nitrous oxide provides a significant cooling effect on the intake air. When you reduce the intake air temperature, you increase the air's density, and this provides even more oxygen inside the cylinder.

Examples of cheating in NASCAR

• NASCAR inspectors, preparing to do tests on horsepower numbers following Saturday's Nationwide race at Michigan International Speedway, found magnets under the gas pedals on the two Gibbs Toyotas.

• Tony Stewart, making his last Nationwide start for the Gibbs team, finished third in the No. 20, and 18-year-old rookie Joey Logano was seventh in the No. 18. The race was won by CarlEdwards  in a Ford.

• Toyota  has won 15 of 25 races this season in Nationwide, and all but one came in a Camry fielded by Gibbs. The exception was JGR driver Kyle Busch's victory at Charlotte in May in a car fielded by Braun Racing.

• In the face of such domination, last month NASCAR ordered the Toyota Nationwide teams to use a smaller spacer to cut about 15 horsepower in their motors.

• The incident Saturday was apparently an effort to keep the current numbers from looking too strong in the latest test.

• "In our post-race inspection — yesterday was the day we were going to chassis dyno cars — our inspectors discovered some shims that were placed on the gas pedal stop," Robin Pemberton, vice president of competition for NASCAR, said Sunday. "It was magnets that were about a quarter-inch thick that prevented the accelerator from going 100 percent wide open.
