The Effect Of Ethanol On The Production Of Ethanol

he experimental variable in this experiment was the changing number of Alka Seltzer tablets that were put into the 250mL beaker of vinegar. Some of the control variables in this experiment were that the same beaker and thermometer were used for each trial, the same type of vinegar and Alka Seltzer were used for each trial, and the same amount of vinegar. The original Hypothesis was that more Alka Seltzer would increase the temperature of the vinegar was not correct. After analyzing the data it can be seen that for the first trial the temperature did not change as it stayed at 24 degrees Celsius before and during the reaction with 1 tablet, also for trial two with two tablets the temperature stayed the same at 23 degrees Celsius and did

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

Planning My aim for this experiment is to see the energy produced from different alcohols. This investigation involves burning alcohol in the air. ‘GCSE Chemistry’ by B.Earl and L.D.R Wilford says that "alcohols form, another homologous series, with the general formula Cn H2n+1OH ". The alcohol reacts with the oxygen in the air to form the products water and carbon dioxide.

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

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).

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.

When conducting the experiment the results for each alcohol were where they were anticipated to be supporting the

In the United States of America, corn ethanol is the main raw material we use to move our vehicles to accomplish our daily goals. Obviously, corn ethanol is presenting ethanol by corn. The biomass in the ethanol adds fermentation, a system that breaks down any chemicals or other substance in any liquid. Additionally, it is added distillation, the action of purifying the process of heating and cooling. This is how corn ethanol is made.

Ethyl Alcohol or Ethanol is the ingredient found in beer, and wine that causes drunkenness. Alcohol is formed when

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.

Ethanol fuel is typically just made from plant biomass by pretreatment, fermentation, and distillation, which is very much the same way that beer and liquors are produced.

Beaker B had the slowest rate of fermentation due to the temperature being the lowest (see table; Temperature and Time). However, both Beaker B and C were still going through a color change when time for the experiment ran out. It is unclear how long the experiment would have to be continued in order to see a full color change, but it can be predicted or hypothesized that Beaker B would have the greatest amount of time until a full color change occurred. Beaker C had the second greatest rate of fermentation occur due to the temperature being the second highest in the experiment. The results did support the hypothesis for this lab which stated that test tube that was introduced to the highest temperature would have the greatest rate of fermentation

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.

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.

drop one of them and it was to shatter, you must not pick it up
