The benzoin product was recrystallized by dissolving with a H2O/95% ethanol (2:1‚ v/v) solution and heated to reflux. Vacuum filtration was used to wash and dry the product.

alternative to oil production. K‚ Ethan.‚ Energy Refuge. Web. 2006. Energy Refuge‚ written by Ethan K.‚ is an informative article about the important role that ethanol is bringing into the automotive industry and claims that it is a sustainable source of energy for our vehicles to use. He develops this claim by talking about how ethanol would work‚ and why it can be more beneficial than oil production for vehicles. Ethan’s purpose is to bring to everyone’s attention that there are alternative products

the hydrogen peroxide. Denatured enzymes are enzymes whose shape has been altered and are no longer active (Wiggins). Ethanol is able to denature enzymes and caused the enzymes in the potato piece to be unable to function. This caused the ethanol-soaked potato to have less activity than the water-soaked potato since it did not have its enzymes denaturized like the one soaked in ethanol.

A developed country does have a moral duty to produce food over fuel crops when hunger is global issue. Allowing someone to go hungry to be able to fuel a vehicle is immoral. There is a moral duty to make sure that America is not consuming all our food sources to lessen the cost of our fuel imports. Food should be in demand and be available for the poor. It is important to be able to curve the hunger with a source that has many options for usage. Farmers grow corn to feed their animals‚ family

of the Pigmentation of an Onion Cell within 40% Ethanol and Deionized Water Purpose: To measure the amount of pigment in a solution of 40% ethanol and deionized water both containing pieces of an onion with a spectrometer. Hypothesis: 40% ethanol breaks down the cell creating less surface area and spreading out the pigment while the deionized water absorbs the pigment in a greater surface area. Procedure: Add 10ml of deionized water and 40% ethanol to a 6-dram vial Add 6g of chopped onion to the

reactivity of its double bond‚ is readily transformed into many useful products Ethylene‚ because of the high reactivity of its double bond‚ can form many useful products‚ such as plastics (polyethylene). For example‚ ethene can react with water to form ethanol‚ with a H3PO4 catalyst at 300oC. Ethene can react with oxygen in the presence of an Ag catalyst and at 250oC‚ to form ethylene oxide‚ which is further treated with dilute acid solution to form ethylene glycol. Ethene can also react with oxygen‚ with
