From Wiktionary under the GNU Free Documentation License. Ethanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. It is a powerful psychoactive drug and one of the oldest recreational drugs. It is best known as the type of alcohol found in alcoholic beverages and thermometers. In common usage, it is often referred to simply as alcohol or spirits. Ethanol is a straight-chain alcohol, and its molecular formula is C2H5OH. Its empirical formula is C2H6O. An alternative notation is CH3–CH2–OH, which indicates that the carbon of a methyl group (CH3–) is attached to the carbon of a methylene group (–CH2–), which is attached to the oxygen of a hydroxyl group (–OH). It is a constitutional isomer of dimethyl ether. Ethanol is often abbreviated as EtOH, using the common organic chemistry notation of representing the ethyl group (C2H5) with Et. The fermentation of sugar into ethanol is one of the earliest organic reactions employed by humanity. The intoxicating effects of ethanol consumption have been known since ancient times. In modern times, ethanol intended for industrial use is also produced from by-products of petroleum refining. Ethanol has widespread use as a solvent of substances intended for human contact or consumption, including scents, flavorings, colorings, and medicines. In chemistry, it is both an essential solvent and a feedstock for the synthesis of other products. It has a long history as a fuel for heat and light, and more recently as a fuel for internal combustion engines. From Wikipedia under the
GNU Free Documentation License What does the compostion of ethanol and water have to do with the reason for ethanol boiling first? Q. if that makes sense, where it has to do with the hydrogen bonding and the polar/nonpolar ends that make the ethanol vaporize before the water. other wise. why does ethanol have a lover boiling point than water? Asked by Sara S - Mon Oct 1 22:50:25 2007 - - 2 Answers - 0 Comments A. ethanol is not as polar as water. Water is an extremely polar molecule, this is often described by the hydrogen bonds present in water. This causes there to be strong intermolecular forces. Since the intermolecular forces of water are much stronger than those of ethanol, it causes water to stay in the liquid form for longer. Answered by Skeez - Mon Oct 1 22:56:08 2007 How many ppm and % is 390000 mg/L of ethanol in a 200mL bottle of water? Q. I have a 200mL bottle of water that has been contaminated with ethanol. The concentration of ethanol is 39000 mg/L. What is the percentage of the bottle that is ethanol and how many parts per million of ethanol are in the bottle? Asked by jas114 - Thu Jan 10 15:57:18 2008 - - 1 Answers - 0 Comments A. Percentage and parts per million are dimensionless quantities. Assuming a solution density of 1g/mL, the ethanol percentage is calculated as follows: 39000 mg/L * 1L/1000mL * 1g/1000mg * 1g/mL= 0.39g/g Multiply the above dimensionless result by 100% for the percentage (39%), or multiply the result by 10^6 ppm for the parts per million (39000 ppm).

Q. Since E85 ethanol has a lower octane..which means it has a lower combustion temperature...does that mean the pistons have to be smaller to reach the optimum height required to propel the vehicle? Asked by narlysnow - Wed Jun 25 17:33:38 2008 - - 1 Answers - 0 Comments A. E85 is higher in octane than regular gas. If your car is a flex fuel car then nothing needs to be done. The only difference is that E85 does not have as many BTU's as straight gas Answered by kds11860 - Wed Jun 25 17:43:41 2008 From Yahoo Answer Search: "ethanol" See also:
