The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver‚ ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm‚ and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation‚ this means that the more diluted the solution of 95% ethanol was‚ the less oxygen gas collected. Controlling

A Comparative Study On The Combustibility Of Ethanol (C2H5OH) And Hydrogen Peroxide (H2O2) Mixtures As Fuel Chemistry January 31‚ 2013 Revised February 15‚ 2013 Abstract In this experiment‚ the proponents used mixtures with varied proportions of ethanol and hydrogen peroxide to know which would make a more efficient‚ clean‚ and stable combination. Compared to conventional fuels‚ ethanol contains 36% oxygen thus resulting in more complete combustion. This greatly lowers

is that corn is used in ethanol. For higher yields of corn farmers and scientists have turned to genetic engineering. Corn has a big impact on Illinois‚ corn helps our economy as a crop and as a part in ethanol production‚ and through genetic engineering of corn. Food As one should know corn can be eaten by humans. Corn has been feeding humans for a long time. Now that the

The chemical formula for fuel CH3CH2OH‚ it is also known as Ethyl alcohol and can be found as several ’Blends’. This type of energy‚ Ethanol can be used as

Subject Content Most of the objectives specified in this section relate to Knowledge with Understanding‚ although some indication has been given as to where the skills of Handling Information and Solving Problems may be developed. Teachers are reminded that‚ in the written papers‚ 40% of the marks are allocated to these higher ’thinking’ skills. In almost every section‚ students should therefore be given practice at dealing with unfamiliar situations so that these higher thinking skills can be developed

Abstract A distillation experiment was performed in attempt to separate two miscible fluids.This experiment used fractional distillation to separate ethanol from the azeotropic mixture of ethanol and water. The initial composition of the solution did not matter because the goal of the experiment was to distill the ethanol-water solution and obtain 95% ethanol in the distilled fraction. The percentage composition is obtained by the calculated density of distilled product. The azeotropicmixture was separated

alternative energy : bio fuel - "Ethanol in the Race of the Bio-Fuels " By: Thomas Dwyane Much talk has been going on about the use of the so-called alternative fuel sources in order to answer the demand of preserving the environment. One of the highest possible sources of this alternative fuel is ethanol‚ or that fuel which is derived from corn. Ethanol‚ also known as ethyl alcohol or grain alcohol or more commonly referred to simply as alcohol‚ is a flammable‚ colorless‚ and slightly toxic chemical

Physical Properties Table 1: Differences of BIT and Commercial Ethanol in Density and Smoke Emission Properties BIT (MEAN) Ethanol (MEAN) Density 300 kg/m^3 354.64 kg/m^3 Smoke Emission Clear Clear In table 1‚ the researchers compared the physical properties such as the density and smoke emission of BIT and commercial ethanol. The density of BIT which was the 300 kg/m^3 was obtained by using the formula of mass over

particular lab‚ one might have a researchable question as so: "Does ethanol effect cell membranes?" To this question many hypotheses were formed. For this personal experiment‚ if the concentration of ethanol is increased‚ then it is expected that the cell membrane of the beet root will be damaged‚ resulting in the release of more betacyanin. To test this‚ a beet root was cut into identical portions to then be soaked in various ethanol solutions for five minutes each. After the incubation‚ the absorbance
