Generally ethanol is an alcohol found in alcoholic drinks. At 100% concentration, it is pure and a colourless liquid with a strong odour (due to weak Van der Wall forces :D. Ethanol is produced by the fermentation of carbohydrates in yeast cells and is used frequently as a solvent.
Alcoholic beverages are the only consumable products in the U.S. that do not have nutrition labels. Consumers are being kept in the dark about serving size, alcoholic content, calories, carbohydrates, fats, protein, cholesterol and other nutrition information. Alcohol, specifically ethyl alcohol or ethanol, is produced by fermenting the starch or sugar in various fruits and grains. Alcoholic beverages produced by fermentation and distillation include beer that is usually about 4 to 6 % alcohol, wine that is usually 7 to 15% alcohol, and hard liquor which is about 45% alcohol.
Alcohol has long been a subject of controversy. Long before man understood the indications and contraindications of alcohol there has been laws against this drug. Classifying alcohol as a drug may not be suited for a majority of the population because people like to partake in drinking. Imbibing in alcohol is a tradition in many parts of the country. We use alcohol for celebrations, traditions, socialization and combining food flavors with specific alcohols. Forgetting that too much can lead to many issues and problems like alcoholism, liver disease and contraindications with other medications. Alcohol was extremely detrimental to the native Americans of this land.
In the words of John McCain, “corn-based ethanol has been a case study in the law of unintended consequences” (Stossel 00:00:43-00:00:48). This news would astonish most because the general public has been told that ethanol is beneficial for the United States, due to it being a renewable resource, however, that is not true. When one thinks of the qualities of a renewable resource, they think of it being beneficial to the environment, having a positive energy balance, not requiring subsidies, mandates, and tariffs to function, and should not raise the price of its main input. Most renewable resources meet these goals, corn ethanol, however, does not meet any of these goals. It is safe to call ethanol a false economy because it does not have any
Are you tired of paying those high fuel prices at the pump every time you go to fill up your vehicle? The ever-rising price for a barrel of foreign oil has most American citizens really watching where they drive. A majority of the people is not aware that there is an alternative to the problem. It is startling to think that there is a fuel source here on our own soil that most people pass everyday and do not even think about it.
Alcohol or ethanol, is an intoxicating ingredient found in beer, wine, and liquor. Alcohol is produced by the fermentation of yeast, sugars, and starches. This fermentation of fruits, grains have been used for thousands of years by humans to make alcoholic drinks and beverages .
Overall, there was much to be learned from this experiment – even including the error that was seen throughout the experiment in our incorrect data points as we attempted to find the percent ethanol in Busch’s, Busch’s Light, and Busch’s nonalcoholic beers – of which we did not get close to in the slightest. The calibration method resulted in a number that made sense for the extraction sample of an original 5% in water solution, 3.46%. The week two experiment resulted in a large amount of error, meaning that the conclusions drawn were not accurate, even though theoretically the standard addition solution should have had more accurate results. The main problem set out to be solved is finding ethanol percent in solutions of which the ethanol
Figure 5 - Michaelis Menten Graph of Ethanol (pH 9.0) Representing the Velocity versus Substrate Concentration. Different concentrations of ethanol were used, and the absorbance reading taken through enzyme kinetics. The velocity was calculated through the conversion of the slope of the data points to abs/min. K_m was found to be 5.76×〖10〗^(-3) M, V_max 1.71×〖10〗^(-3) M/min, K_cat 2.85×〖10〗^(-2) 〖min〗^(-1), and K_cat/K_m 4.94 〖min〗^(-1) M^(-1).
There are two common methods to make ethanol from corn (Rendleman 6). They mostly differ in the way that the corn is prepared. The first step is to grind the corn. In wet milling, the starch-containing kernels of corn are separated from the other parts before grinding, since the starch is the only part of the corn that will convert to ethanol
Ethanol or as we know as alcohol in our beverages can be made from any fruit or vegetable that performs photosynthesis which produces glucose shown As required as the reactant of the previous equations.
When conducting the experiment the results for each alcohol were where they were anticipated to be supporting the
In the world of global warming, all kinds of pollution and fuel shortages going on, renewable and clean/ green energy is increasingly the ideal solution of energy related problems we have to solve one way or another. Biofuel is one of the mainstream and highly supported solutions nowadays, an idea to make renewable fuel by living organisms such as fiber, corn, vegetable oil or sugar cane. Unlike nonrenewable fossil fuels over extracted by people causing various environmental problems like generating a considerable amount greenhouse gas, current technology already lets renewable fuel like biofuels to shrink a certain amount of greenhouse gas production, making it a more ‘clean’ source of energy.
