What energy source produces carbon dioxide and water when burned?
Any fossil fuels, hydrocarbons like coal, oil and natural gas, release carbon dioxide and water when burned.
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!
Is ethanol potential or kinetic?
Since ethanol by itself is a liquid that is doing nothing, it is POTENTIAL energy. You need to take some action to extract the energy.
What happens to the hydrogen when a candle burns?
The hydrogen within the paraffin of a candle (the wax) severs its bonds with the carbon (the other element in the paraffin) because the energy the heat produces is enough to do so. The hydrogen then bonds with the oxygen atoms around it, and forms H2O. You can test this by covering a lit candle with a clear beaker. You will observe that water condenses around the flame.
When a fossil fuel is burned what energy is converted into kinetic energy?
When fossil fuels are burned they turn into mercury which released into the atmosphere
Ethanol is a fuel that can be made from corn How many kJ of heat energy are released when 3.00 kg of ethanol are burned?
-91750 - -91650 the hole thing
What energy source produces carbon dioxide and water when burned?

Do the burning of fuels such as coal release electrical energy?
The burning of coal itself does not release electrical energy, coal is burned to drive a turbine, the turbine in turn produces electricity.
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 are energy transformations in a coal fired power station?
Coal is burned to produce heat, which then is transferred to water/steam, which produces mechanical power in the steam turbine, which produces electrical power from the generator

Which is the best alcohol at producing energy and why?
Ethanol, due to it's inherent properties as a fuel. Brazil produces alot of Ethanol and is about to become energy independent because of it. But check this out: Crops such as corn, Sugar cane, beets, etc.. are converted to alcohol. In the case of corn to ethanol, it is energy negative. It takes 71% more energy to produce ethanol than is obtained from the ethanol. Also, using grain such as corn for fuel precludes it from being used as food for humans or livestock. It is also hard on the land. In United States corn production, soil erodes some 20-times faster than soil is formed. Ethanol has less energy per volume than does gasoline, so more gasoline has to be purchased to make up the difference. Also, ethanol is not environmentally friendly, as advocates would like to believe. Pimentel (1998) states: "Ethanol produces less carbon monoxide than gasoline, but it produces just as much nitrous oxides as gasoline. In addition, ethanol adds aldehydes and alcohol to the atmosphere, all of which are carcinogenic. When all air pollutants associated with the entire ethanol system are measured, ethanol production is found to contribute to major air pollution problems." With a lower energy density than gasoline, and adding the petroleum energy used to plow, plant, cultivate, and transport the corn for ethanol production, ethanol does not save gasoline nor does it's use reduce atmospheric pollution. A comprehensive study of converting biomass to liquid fuels by Giampietro and others (1997) concludes: "Large-scale biofuel production is not an alternative to the current use of oil, and is not even an advisable option to cover a significant fraction of it." Solar Energy is the only way to fly ;-)
How can corn ethanol make enough energy to power a car?
Ethanol stores chemical energy, just like gasoline does.
When fuels are burned they transfer energy what type of energy is in the fuel and what energy is it converted into when its burned?
The energy that is contained in a consumable fuel (like gasoline) is chemical energy. The energy that it is converted into when it is burned is heat energy.
What is the energy source of ethanol?
corn
How are fossil fuels used in a power station to generate energy?
fossil fuels are burned to create steam which turns these huge turbines which produces electricity hope this helped it is also a form of energy
Which conatians more energy parafine or methalted spirits?
Paraffin Wax does
