What amount of ethanol is needed to produce the equilavent a liter of petrol energy wise?
Ethanol contains less than half the energy per litre as is contained in an equal amount of petrol (Petrol= 77.3 MJ/kg, Ethanol = 29.7 MJ/kg.) This does nor account for the higher production energy costs associated with production of fuel grade ethanol from food grade crops like wheat or corn.
You would have to burn more than twice the volume of fuel in an ethanol powered car.

What is the heat of reaction for ethanol fermentation from glucose?
The heat of reaction for ethanol fermentation from glucose is exothermic, meaning it releases heat. This is because the process of fermentation involves breaking down glucose to produce ethanol and carbon dioxide, which releases energy in the form of heat.
Is ethanol potential or kinetic?
Ethanol is a chemical compound and therefore does not have kinetic or potential energy itself. However, when ethanol is burned as a fuel, it releases energy in the form of heat, which is a form of kinetic energy.
How is electricity geneerated using ethanol?
Well ethanol is burned according to the equation: C2H5OH(g) + 3 O2(g) → 2 CO2(g) + 3 H2O(l); (ΔHr = −1409 kJ/mol) where delta h (-1409 kJ/mol) amount of energy given off per one mole of ethanol which is combusted. There are two ways to harness the energy given off: Internal combustion engine -like a car the explosion caused by ethanol and oxygen is used to move a cylinder. But for electricity the ethanol will be burned and the heat used to heat water until it turns to steam. The pressure generated by the steam is used to turn a turbine which rotates magnets around a coil of wire which generates electricity! hope it helps!
What is the Latent heat of vapourisation of ethanol?
The latent heat of vaporization of ethanol is approximately 38.6 kJ/mol at its boiling point of 78.37°C. This is the amount of energy required to transform a liquid into a gas at a constant temperature.
What happens when ethanol burns in air?
When ethanol burns in air, it reacts with oxygen to produce carbon dioxide, water vapor, and heat. This is a combustion reaction where ethanol acts as a fuel source and undergoes oxidation to release energy in the form of heat. The balanced chemical equation for the combustion of ethanol is: C2H5OH + 3O2 -> 2CO2 + 3H2O.
How much energy does it take to make ethanol fuel?
The energy required to produce ethanol fuel varies depending on the production process, but it typically takes about 0.25-0.3 kWh of energy to produce one liter of ethanol. This includes energy inputs for growing and harvesting the feedstock, processing it into ethanol, and distilling the ethanol.
How does ethanol hurt the environment?
It takes more energy to produce ethanol than the fuel itself yields.
How much energy does it take to produce a gallon of ethanol?
couple hundred
What is a major drawback of ethanol?
Two drinks and I have to get a taxi home. As an energy source, the process of concentrating ethanol consumes a lot of energy. It depends on who you believe, but the amount of energy consumed may exceed the amount of energy in the ethanol created. If that's so, then ethanol may be a useful form of energy (in the same was as electricity is), but not a useful source of energy.
What is the energy source of ethanol?
The energy source of ethanol is renewable plant material, such as corn, sugar cane, or cellulose from wood or grasses. This plant material undergoes fermentation to produce ethanol, which can be used as a fuel source.
Which material would require the least amount of energy to change 1kg from a solid to a liquid ethanol aluminum propane or water?
Water would require the least amount of energy to change 1kg from a solid to a liquid because it has a lower melting point compared to the other materials listed (ethanol, aluminum, propane).
What is the molar heat of fusion of ethanol?
The molar heat of fusion of ethanol is approximately 5.02 kJ/mol. This is the amount of energy required to convert one mole of solid ethanol into liquid ethanol at its melting point of -114.1°C.
Does petroleum produce energy?
Yes, a huge amount
What elements will be present in the substances that are created when ethanol burns?
The products of burning ethanol are carbon dioxide (CO2) and water (H2O). When ethanol undergoes combustion, it reacts with oxygen to produce these two substances along with heat and light energy.
What gas is produced when yeast respire anaerobically?
When yeast respires anaerobically it takes glucose (C6H12O6) and breaks it into ethanol, a small amount of energy, and two molecules of carbon dioxide gas (2CO2).
What is the heat of reaction for ethanol fermentation from glucose?
The heat of reaction for ethanol fermentation from glucose is exothermic, meaning it releases heat. This is because the process of fermentation involves breaking down glucose to produce ethanol and carbon dioxide, which releases energy in the form of heat.
What are examples of bad biofuels?
Corn derived ethanol. Anything that requires more energy to produce than is derived from the final product.
