    6. The first step in metabolism of ethanol in humans is the oxidation of ethanol to acetyldehyde by the enzyme alcohol dehydrogenase (ADH). At 298 K and pH=7.0, ethanol is incubated with ADH and the concentration of ethanol and acetyldehydee is measured over time. a. Using the results above, calculate the standard free energy change (ΔGº’) for this reaction. Explain your calculations. The standard free energy change can be expressed through the formula ΔGº’=-R(gas constant) T(temp in Kelvin) lnK’eq. K’eq is equal to the products of a reaction over the reactants of a reaction, or Products/Reactants. So, K equilibrium of this question would be 3.5 (Acetaldehyde)/6512.3 (Ethanol) because this is where equilibrium is reached. So the K’eq=5.37x10-4. So to determine the ΔGº’, -R= -1.987 cal/mol K, T=298 K, and lnK’eq=-7.53. This would make the equation= -1.987(298)ln(7.53). ΔGº’ comes out to equal ~-1195. b. After dinner and a few drinks, the concentration of ethanol in a cell is measured to be 3412 mol/L and the concentration of acetaldehyde is measured to be 1.4 mol/L. Calculate ΔG’ and explain…

    (Un) substituted-2-phenyl-4H-3, 1-benzoxazin-4 one (1, 2) was converted to 3-amino-2-phenylquinazolin-4(3H)-one and its substituted analog under reflux for 6-7 hr with hydrazine monohydrate in ethanol. The concentrated solution was poured into ice cold water to obtain a solid product. The obtained solid was washed with water, filtered, dried and recrystallized from ethanol1. Synthesis of 3-(benzylideneamino)-2-phenylquinazolin-4-(3H)-one 5 (a-j) A mixture of 3-amino-2-phenyl-3H-quinazoline-4-one…

    When Ethanol is burned the some of its matter is burned causing the Ethanol to lose mass. This is supported by the fact that on average the mass of the ethanol after burning was 2.245 kg less than before burning. Another way we can see that the ethanol was losing mass was was that after 20 minutes we could see a product of the ethanol burning, we could see some water vapor on the box covering the Ethanol and BTB. Because matter can not be created or destroyed to get water in the box some of the…

    the fuel source, Ethanol. Whether you support the idea or not, it’s at nearly every gas station across the state. Ethanol burns cleaner emissions, lowers gas prices, and is a renewable source of energy. But some think it’s not worth creating Ethanol because it raises food prices, it requires too much energy to create than what is being yielded, and there are better ways to save oil. The truth is, these are partially true, but they still aren’t enough to stop Ethanol production. America should…

    overwhelming sense of pride seemed to deflate a little when I filled the tank on my 1999 Nissan frontier for the first time. I could hardly believe my eyes when I saw the total $40. This shocking experience not only scared me for life but also made me determined to find a cheaper way to fuel my truck. That is where I found ethanol. Ethanol is a biofuel derived from corn that can be used to fuel cars and trucks that are flex fuel compatible. “In 1908, Ford Motor Company’s first car, The Model T,…

    let the technology drive its own economics. If ethanol is technically viable, it will discover its own place in the economy. When it is highly subsidized, there is no way to tell where it’s true economic strength lies. “Ethanol is propped up by more than 200 tax breaks and subsidies worth at least $5.5 billion a year” (Goodell). And unfortunately biofuel production is such a huge part of the U.S. economy that removing the financial support could cause an economic meltdown the full extent of…

    An essay about Environmental, economic and energetic costs and benefits of biodiesel and ethanol biofuels. By Jason Hill et al. The authors try to determine whether ethanol, produced from corn grain, and biodiesel, produced from soybeans provide benefits over the petroleum-based fuels they displace. To be a viable alternative to fossil fuels, a biofuel (ethanol or biodiesel) should provide a net energy gain, have superior environmental benefits, be economically competitive with fossil fuels and…

    This paper reviews articles that report on research and studies of the effect of increased use of corn ethanol on our country and global warming in the United States. When first introduced the production of ethanol from corn was a very popular idea. This favored alternative was meant to reduce carbon dioxide emissions, bring about energy independence, to raise the income of farmers, and to produce more rural employment. Recently, however, corn ethanol has been the topic of heated debate on…

    Corn ethanol or sugarcane ethanol? for most people who haven't heard of these two fuel resources, it sounds like something almost impossible to do, powering your vehicle with sugar cane and corn. A question that is slowly coming to light due to the high demand for eco-friendly vehicles. These are both fuel resources that have recently been introduced into our list of choices for fuel. Throughout the following paragraphs, we will discuss the differences or similarities between these two fuel…

    billion internal combustion powered vehicles on the planet and they all run on oil. It takes uncounted barrels of oil to make those cars and engines in the first place, and you cannot plug any new technology into an internal combustion powered engine. Plus there’s seven gallons of oil in every tire. Nobody will ever make a billion new internal combustion anything because there isn’t going to be enough oil. Ethanol Ethanol is an absolute joke. First of all, a very brilliant scientist, David…
