Combustions Reactions : 

Combustions Reactions Natalie Martinez Period 1/2

What are the different types of chemical reactions? : 

What are the different types of chemical reactions? Combustion-C10H8 + 12 O2 ---> 10 CO2 + 4 H2O Synthesis-(8 Fe + S8 ---> 8 FeS) Decomposition-(2 H2O ---> 2 H2 + O2) Single displacement-(Mg + 2 H2O ---> Mg(OH)2 + H2) Double displacement-(Pb(NO3)2 + 2 KI ---> PbI2 + 2 KNO3) Acid-base-(HBr+ NaOH --->NaBr + H2O)

What is a combustion reaction? : 

What is a combustion reaction? A combustion reaction takes place when a fuel and an oxidant react, producing heat or heat and light.

What is the fire triangle? : 

What is the fire triangle? Oxygen, heat, and fuel

What is activation energy? : 

What is activation energy? Activation energy is the energy that must be overcome in order for a chemical reaction to occur.

Why is heat/energy a necessary part of a fire triangle? : 

Why is heat/energy a necessary part of a fire triangle? It is important because without heat, a fire cannot begin.

How is the cook top of your stove a real-life example of a fire triangle? : 

How is the cook top of your stove a real-life example of a fire triangle? Cook tops need heat, oxygen, and fuel to make them hot.

What is a combustion engine? : 

What is a combustion engine? It is an engine where fossil fuel occurs with an oxidizer in a combustion chamber. In this engine, the expansion of the high temperature and pressure gases directly apply a force to the pistons or turbine blades and generate mechanical energy.

How does a combustion engine work? : 

How does a combustion engine work? The fuel is burned inside the engine the gasoline goes in the combustion chamber. Once the gas of the gasoline expands, it produces energy. The more compressed the mixture of air and fuel, the higher the risk of catching fire. This is why high octane gas is recommended for high performance cars.

How are NASCAR engines different from street car engines that allow them to operate at much higher speeds? : 

How are NASCAR engines different from street car engines that allow them to operate at much higher speeds? The cubic inches of the engine in a NASCAR race care must be the same as the cubic inches of the street car engine they represent. Other than that there is virtually nothing similar to between a NASCAR engine and a street car engine. They use different engine blocks, piston, alternators, suspension, electronics, etc. NASCAR engines even run on leaded fuel still.

How does nitrous oxide help engines perform better? : 

How does nitrous oxide help engines perform better? By having more oxygen available during combustion. With more oxygen, more fuel can be injected and the engine can produce more power. Its just a simple way to give off horsepower.

Examples of cheating in NASCAR : 

Examples of cheating in NASCAR Smokey Yunick, the greatest rule-bender in motorsports history, described as slipping past NASCAR inspectors as “walking under the snakes belly” and that was long before the rule book became the airtight list of guidelines it is today. Cheating is a time-honored racing tradition, but it rarely makes as many headlines as it did at this years Daytona 500. six Nextel cup teams got collared- including the cars of Michael Waltrip, Matt Kenseth and Kasey Kahne-resulting in 5 crew chief suspensions, 500 total points docked from drivers and owners and $250,000 in fines.
