The abstract below was written by Melanie Shadish. It came so close (along with its support documents) to what I wanted that I have added nothing from abstracts by other students. Yes there is some editing that needs to be done‚ but this one person understood the exercise and communicated that understanding very well.

promote production of ethanol and (b) place tariff barriers on imports of sugar cane? Who suffers as a result of these policies? ANS: Benefiters in promoting production of ethanol: -Corn producers. They get subsidies from the government and get a free way of marketing from the government. The government promotes consumption of ethanol‚ ethanol is produced out of corn‚ so indirect marketing for corn farmers that will get more demand out of policies that promote ethanol. -Ethanol sellers. -People

This doesn’t even take into consideration that it takes at least 2/3 gallon of fossil fuel‚ by the US Department of Energy’s own figures‚ to produce one gallon of ethanol. (2) (Ethanol producers do not use ethanol to produce ethanol because it is too expensive.) Why do we do this Why do we do this? Because our policy makers have come to believe that the air-born plant food carbon dioxide is a “pollutant” (3) that must be reduced or severe

organic solvents The emulsion test is a method to determine the presence of lipids using wet chemistry. The procedure is for the sample to be suspended in ethanol‚ allowing lipids present to dissolve (lipids are soluble in alcohols). The liquid (alcohol with dissolved fat) is then decanted into water. Since lipids do not dissolve in water‚ when the ethanol is diluted‚ it

The investigation was designed to determine the effect of the addition of increasing concentrations of a miscible liquid (ethanol) on the solubility of KNO3 in water. The results of the investigation support the hypothesis that water‚ which exhibits greater polarity‚ is able to dissolve a greater mass of KNO3 at lower temperatures compared to tested concentrations of Ethanol ranging from 12.5% to 30%. Furthermore‚ the results of the graph 1 show correspondence to the dielectric constant of each solvent

This is because the density of water is 1.0 g/mL‚ and the product should have had a mixture of ethanol and water‚ making the density lower. The measured weight of the vials and ethanol were incorrect due the scales.There are many factors that can cause a scale not to read the correct value. The first is the airflow underneath the weighing plate majorly affects the values read. For instance
