Organic vs Conventional Essay Organic food‚ which was once only found in health food stores‚ is now a regular feature at most grocery stores‚ and has created a bit of a dilemma in the produce aisle. On one hand‚ you have an organically grown apple. On the other hand‚ you have an apple that was grown conventionally. Both of these apples are shiny‚ red‚ and firm. Both provide us with vitamins and fiber‚ and both are free from sodium‚ fat‚ and cholesterol. Which should you choose? For many reasons

Here’s a good example from engineering. An aerospace engineer might want to graph the lift of a wing versus the size of the wing‚ and he wants to show everything from an insect wing all the way up to a jumbo jet. A fly’s wing is maybe 0.1 inch long‚ and a jumbo jet wing might be 1000 inches long (about 80 ft). It would be pretty tough to put more than one insect on that graph - if you scale the wing length axis to fit on a sheet of paper‚ all the points for insect wings would be jammed up against

Copper and Formula of a Copper Compound Sofia Economides Date Preformed: 3/19/2012 Date Submitted: 3/26/2012 Lab Partners: Anita Smith‚ Taylor Bell‚ Derek Bourgeois 1. Purpose a. To determine the percent of copper and the formula weight of a copper compound. 2. Introduction a. Magnesium is a very active metal which can reduce copper (II) ions in a weight sample of a compound to metallic copper. The reduction of copper ions in a compound to a copper metal is caused

When it comes to organic chemistry and the synthesis of specific products there is an abundant amount of routes that can be taken and still get you the same result. For the following experiment‚ the main focus is the use of a cycloaddition reaction‚ also known as Diels-Alder. According to the lab manual‚ this reaction consists of the addition of a diene and a dienophile and that the Diels-Alder reaction builds stereospecific ring compounds with ease (Weldegirma 80). The reaction takes place between

chains the location of the hydroxyl group determines chain numbering. For example: (CH3)2C=CHCH(OH)CH3 is 4-methyl-3-penten-2-ol. Other examples of IUPAC nomenclature are shown below‚ together with the common names often used for some of the simpler compounds. For the mono-functional alcohols‚ this common system consists of naming the alkyl group followed by the word alcohol. Alcohols may also be classified as primary‚ 1º‚ secondary‚ 2º & tertiary‚ 3º‚ in the same manner as alkyl halides. This terminology
