What are the chemical reactions in internal combustion engine?
Internal combustion engines usually use some kind of hydrocarbon fuel (gasoline for example). The fuel is burned together with the oxidizer (atmospheric air in most cases with the exception of rocket engines). The result of the chemical reaction between the hydrocarbon fuel and air is H2O, CO2 and, in smaller quantities (depending on the proportions in which the fuel and air are mixed into the combustion chamber), some radicals like CO, OH, O, H maybe even C solid particles (also known as soot). The process is not as simple as it is taught in high school chemistry as there's no single reaction leading from reactants to final products. There are many reactions leading from the decomposition of the gasoline and air molecules to the formation of the final products (all of this reactions form the reaction mechanism).

How does a rocket accelerate away from earth?
A rocket accelerates away from Earth by using propellant combustion in its engines to produce thrust. By expelling exhaust gases at high speeds, the rocket follows Newton's third law of motion, which states that for every action, there is an equal and opposite reaction, propelling the rocket upward. The combination of thrust overcoming the force of gravity enables the rocket to accelerate and eventually break free from Earth's gravity.
Which is a liquid fuel used in rocket engines?
AMMONIA
What are the 2 purposes of liquid oxygen?
Liquid oxygen is used primarily as an oxidizer in rocket propulsion systems to support combustion in engines. It is also used in medical applications to treat patients with respiratory problems or in hyperbaric chambers for therapeutic purposes.
What gas is used up when combustion occurs?
Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species.In a complete combustion reaction, a compound reacts with an oxidizing element, such as oxygen or fluorine, and the products are compounds of each element in the fuel with the oxidizing element. For example: CH4 + 2O2 → CO2 + 2H2O CH2S + 6F2 → CF4 + 2HF + SF6A simpler example can be seen in the combustion of hydrogen and oxygen, which is a commonly used reaction in rocket engines: 2H2 + O2 → 2H2O(g) + heatThe result is water vapor.
The combustion reactions that occur in the engines of a rocket lead to pressure gradients that cause the gaseous products to rush out of the rocket into the atmosphere. What is created by this process?
Thrust
When combustion reactions occur inside a rocket's engine a lot of heat and pressure are released The pressure gradient is much larger inside the rocket than outside which causes the?
thrust
Is rocket engines are internal combustion engines?
YES the oxidizer and propelant are mixed into a chamber the ignited.
What is usually used as an oxidizer in a rocket engine?
Liquid oxygen (LOX) is commonly used as an oxidizer in rocket engines due to its high oxidizing power and high density, which allows for efficient combustion reactions in the engine.
Will a D battery ignite a rocket engine?
No, a D battery alone will not ignite a rocket engine. Rocket engines require specific ignition systems and propellants, which typically involve controlled chemical reactions. While a D battery can provide electrical power, it lacks the necessary components to initiate combustion in a rocket engine. Proper ignition systems are designed to handle the unique requirements of rocket fuel and its combustion process.
The combustion reactions inside the engine of a rocket cause a buildup of heat and pressure. When this heat and pressure escapes into the atmosphere, what force is created?
When the heat and pressure from the combustion reactions escape into the atmosphere, they create a force known as thrust. Thrust is the force that propels the rocket forward by expelling gases at high speeds in the opposite direction. This action follows Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Why don't car engines work in space but rocket engines will?
Rocket motors carry their own oxygen supply (oxygen is important for combustion), whereas automobile engines do not - they draw their oxygen from the air taken in from outside the vehicle.
How does fire come out of a rocket at lift off?
At lift-off, a rocket produces fire through the combustion of fuel in its engines. Liquid or solid rocket propellants are ignited in combustion chambers, creating high-pressure gases that expand rapidly. This rapid expansion forces the gases out of the rocket's nozzles at high velocity, generating thrust and propelling the rocket upward. The visible flames are the result of the burning fuel and the hot gases exiting the engine.
Where do the rocket exerts force in pressure?
Rockets exert force at the upper part of the combustion chamber. This pushes the rocket forward.
The combustion reactions inside the engine of a rocket cause a buildup of heat and pressure. When this heat and pressure escapes into the atmosphere what force is created?
Thrust (apex)
What is it called when combustion occur in a rocket's engine and releases heat and pressure making a larger pressure gradient inside the rocket than outside which causes the gaseous products?
This process is called thrust generation. The combustion of propellant in the rocket engine produces high-pressure gases that are expelled through a nozzle, creating a thrust force in the opposite direction as a reaction. This thrust force propels the rocket forward in accordance with Newton's third law of motion.
What was invented on 1912?
theory of the propeller, compressors for combustion engines, rocket engines, Kaplan turbines, chrome-nickel steel, trans-oceanic ship with a diesel engine
