Ethanol is an alcohol which reacts with oxygen to form water and carbon dioxide:
C2H5OH + 3O2 = 3H20 + 2CO2 Exothermic, so heat is generated.
The reaction is initiated by heat such as match or a spark (but see below about explosive limits). The flash point of ethanol is 9C, so if liquid ethanol is heated to that temperature a spark will ignite it in the presence of oxygen. At 8C, ethanol will not ignite unless the match heats it up by at least one degree.
However, there are certain stipulations, known as the Explosive Limits
The Lower Explosive Limit of Ethanol is 3.5% v/v, meaning that there must be at least 3.5% by volume of ethanol vapor in air for it to ignite, and:
The Upper Explosive Limit of Ethanol is 19% v/v.
If the volume of ethanol vapor in air is above 19% then it cannot ignite due to there being insufficient oxygen for it to ignite. If you rapidly immersed a lighted match into pure liquid ethanol it would extinguish the match due to a lack of oxygen in the liquid.
An addition I forgot to mention:
If you look ate the chemical equation, the atomic weight of hydrogen is 1, of carbon is 12 and of oxygen is 16
So a mole of ethanol will weigh 46g and a mole of 3 oxygen molecules is 96. So you need over twice the weight of oxygen as ethanol for it to burn. If we take the respective volumes of the two molecules at average room temperature, the Upper Explosive Limit is based on the fact that you cannot have that required ratio of oxygen to ethanol if the amount of oxygen present by volume to ethanol is only 81% It must be higher for the reaction to proceed.
What else can I help you with?
When you burn ethanol what do you get?
When you burn ethanol, you get carbon dioxide and water vapor as the main products. This combustion reaction releases energy in the form of heat and light.
What do you get when you burn ethanol?
Burning ethanol produces carbon dioxide and water as byproducts, along with heat energy.
When you dry burn ethanol what does it generate?
When ethanol is dry-burned, it mainly generates carbon dioxide and water vapor as combustion byproducts, along with some carbon monoxide, depending on the conditions of the burn. It is important to note that dry burning ethanol can be dangerous and should be done with caution in a controlled environment.
What gas is given off when you burn ethanol?
When ethanol is burned, it gives off carbon dioxide (CO2) and water vapor (H2O) as the main products.
Why does ethanol burn?
Ethanol burns because it is a flammable liquid that vaporizes easily when heated. When ignited, the vapor mixes with oxygen in the air and undergoes a combustion reaction, releasing heat and producing carbon dioxide and water as byproducts.
What gas is required for ethanol to burn?
Ethanol requires oxygen to burn. During the combustion process, ethanol reacts with oxygen to produce carbon dioxide, water, and heat.
Why do you have to modify vehicles to use ethanol as a fuel?
You don't if the vehicle was designed as a flex fuel vehicle. It can safely burn E85 ethanol. You can burn a mixture of 10% Ethanol in any vehicle.
When you burn ethanol what do you get?
When you burn ethanol, you get carbon dioxide and water vapor as the main products. This combustion reaction releases energy in the form of heat and light.
Why does ethanol burn differently than ethanol and water mixed?
Ethanol burns differently than a mix of ethanol and water because water has a higher boiling point compared to ethanol. Water will absorb heat during combustion, which can lower the overall temperature and affect the efficiency of the burning process. This can lead to a slower and less complete combustion compared to pure ethanol.
What will ethanol fuel do to a 1939 Cadillac?
Burn the valves over time.
What do you get when you burn ethanol?
Burning ethanol produces carbon dioxide and water as byproducts, along with heat energy.
When you dry burn ethanol what does it generate?
When ethanol is dry-burned, it mainly generates carbon dioxide and water vapor as combustion byproducts, along with some carbon monoxide, depending on the conditions of the burn. It is important to note that dry burning ethanol can be dangerous and should be done with caution in a controlled environment.
When you boil ethanol alcohol what gas is released?
This process will only cause ethanol molecules to enter the gas phase. So, it's simply ethanol as a gas leaving the solution
What gas is given off when you burn ethanol?

How is ethanol and oil the same?
Ethanol and oil for fuel are both rather simple liquid hydrocarbons. Both can be used as fuel for internal combustion engines, turbines, and heating units. In many cases, equipment can be designed or retrofitted to burn either. Both burn to form carbon dioxide and water, but their carbon footprints are different. Petroleum is a fossil fuel, but ethanol is not. Petroleum predictably has a pretty specific carbon footprint, but the carbon footprint of ethanol varies according to how it is produced and is somewhat controversial. The production of ethanol could produce very little global warming gas, but it could also produce a lot.
What makes a car burn more gas than usual?
Possibilities:Higher proportion of ethanol in the fuelA lot of extra weight in the vehicle
