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 + SF6
A 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) + heat
The result is water vapor.
What else can I help you with?
Is more oxygen used in an incomplete combustion than a complete combustion?
Yes, more oxygen is used in incomplete combustion compared to complete combustion because incomplete combustion results in the partial burning of the fuel, leading to the formation of more byproducts like carbon monoxide and soot. This requires additional oxygen to combine with these byproducts, using up more oxygen overall.
How can combustion take place?
Combustion , or the ignition of the fuel-air mixture , occurs within the engine's piston cylinders ~ see related link below to a video tutorial .
What term is most used in reference to a combustion reaction?
Combustion reactions are exothermic processes. When substances are burned, heat is given off. An example of this occurs in many homes during the winter. Families burn wood in their fireplaces. This releases energy in the form of heat causing the temperature of the surroundings to increase and warm up the house. In other words, burn is the answer to your questions
What is it called when hot smoke gases up and go to the chimmeny?
This process is called "flue gas exhaust," where hot smoke gases from a fire or combustion process are directed up a chimney or flue to be released into the atmosphere.
4 types of gases?
Oxygen: essential for respiration and combustion. Carbon dioxide: emitted through respiration and combustion, also a greenhouse gas. Nitrogen: makes up the majority of Earth's atmosphere and is crucial for plant growth. Hydrogen: a light and highly flammable gas, often used in fuel cells and as a rocket propellant.
What gas in the air is burning up in burning?
Combustion consumes oxygen.
What happens to the mass of gas after the gas is used up?
After gas is used up, its mass is typically converted into other forms of matter or energy through combustion or chemical reactions. For example, in a car engine, carbon dioxide and water can be produced after the gasoline is burned.
After initial start up how long would you wait until combustion occurs?
7 seconds
Occurs when a gas heats up?
expansion
What causes a the flame to roll out on a gas furnace?
A flame roll-out on a gas furnace typically occurs when there is a blockage in the venting system, causing combustion gases to back up and not exit properly. This can lead to an unsafe condition where the flames extend beyond the burners. Other potential causes include improper air-to-gas mixture, malfunctioning safety controls, or a dirty burner that affects combustion efficiency. Regular maintenance and inspection are essential to prevent this hazardous situation.
When I am cruising down the road not pressing my gas I notice that my car is losing it's power then you press on the gas and then it seems like your car is getting the power back why is this?
Pressing on the gas pedal sends more gas to the combustion chamber for the combustion process which sends more pressure to the engine for your car to pick up speed.
How much useful energy does a gas boiler waste?
Probably about 25 percent of the heat of combustion goes up the stack
What will a burning splint do in nitrogen?
It will go out. Nitrogen, which makes up 79% of the Earth's atmosphere, does not support combustion.
Is more oxygen used in an incomplete combustion than a complete combustion?
Yes, more oxygen is used in incomplete combustion compared to complete combustion because incomplete combustion results in the partial burning of the fuel, leading to the formation of more byproducts like carbon monoxide and soot. This requires additional oxygen to combine with these byproducts, using up more oxygen overall.
Overall efficiency in internal combustion engine?
Not very. only about 15% of the energy is used to drive your car on the road. 62% of the energy is used up in the engine itself, converting the gas to energy. 17% is used when the vehicle idles. 5% is expended in the transmission 2% is used for accessories.
Why does the nitrogen gas has higher amount than that of oxygen gas?
Nitrogen gas makes up around 78% of Earth's atmosphere, whereas oxygen gas accounts for about 21%. This difference is due to the nitrogen-fixing abilities of certain bacteria and the fact that oxygen is more reactive and is often consumed through processes like respiration and combustion.
