...1) General Halogens are a group of nonmetal elements from group 7 of the Periodic Table. It contains fluorine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At). Ununseptium (Uus) is an artificially created element and it is sometimes considered to be a halogen. Halogens have a valency of 1 and a halogen ion has a charge of 1-. Like other groups, there are similarities and trends (both physical and chemical) within the different elements in this group. Below is a table showing the electronic configuration and formula of the halogens. |Halogen |Room temperature (20 oC) |Vapour Colour | |Fluorine |Yellow Gas |Yellow | |Chlorine |Green Gas |Green | |Bromine |Red/Brown Liquid |Orange | |Iodine |Dark Grey/Violet Solid |Purple/Violet | |Astatine |Black Solid |Dark Purple | The halogens become darker as you go down the group. Fluorine is very pale yellow, chlorine is yellow-green and bromine is red-brown. Iodine crystals are shiny purple-black but easily turn into a dark purple vapour when they are warmed up. Common properties The halogens have the following properties in common: • they are non-metals • they have low melting and boiling points • they are brittle when...

...The haloform reaction is one of the oldest known reactions, it dates back to 1822 whenever Serullas accidently discovered an iodine and alkali converted alcohol into iodoform. He called this a “hydroiodide of carbon”. The reaction was not purposely discovered until Guthrie in 1831 whenever he bleach powdered an alcohol and for chloroform. In 1834 Duman formed bromoform by hydrobromite on alcohol. Duman is the one who actually gave haloforms their present name, and also determined their composition. Lieben showed the “iodoform test”, this test is one of the most useful tools for identifying alcohols and ketones. Lieben stated that a positive test will be given if a compound has a CH3CO bond present, this bond must be bonded with a carbon...

...StratSim Simulation Assessment: Firm A Team Members: Timothy McKinney, Alesh Shah, Sami Belbase, Brian Muirhead, Kayleigh Ballantyne Initial Marketing Strategy For our initial strategy we wanted to choose a product line that would be most intriguing to customers in this poor economy. To initiate this we focused our products around better gas mileage, safety, and quality. In order to do this we needed to evaluate consumers’ needs and desires when making a high involvement purchase such as a car. We believe the best target market for this type of car would be a middle class family that does not have as much disposable income due to the recession in our economy. After choosing key characteristics that we believed would make our cars more desirable than the competition, we took an economic approach to our marketing strategy. Our team knew that are best chance to gain more market share would be to go allocate our focus toward a high gas mileage car that does not eat into the pockets of the consumer. With this strategy, middle class families would be able to afford a quality car that did not impair their ability to buy other necessary goods. With this approach our cars would have an advantage in this target market over prestige priced competitors who focus more on luxury then affordability. We believed as a company we could not compete with highly established luxury brands in this market such as BMW, Audi, Lexus, and Mercedes. This leads us to believe...

...Jamie Turner, competent but capricious James Kim & Abbey McDowell Texas A&M University MGMT 372 Dr. Chiaburu 04/20/2014 Modern Lighting Industries, Inc., MLI is a family owned organization that sells lighting units and bulbs to office and warehouse. It has recently been acquired by Specialty Support Services (Triple S) from several financial setbacks due to the death of its founder. It is based outside of Chicago, with fabrication and systems assembly facilities in Illinois, Missouri, and Mexico, and sales and distribution centers in Kansas City and Chicago. There are four departments in this company which are Directing, Controlling, Marketing/Sales and Operations. The company was desperately needed for its vice president position to be filled. So, its new president followed by founder, Pat Cardullo offers to recent unemployed, Jamie Turner with bonuses and possibility of promotion. Turner accepts the offer carelessly, and problems arise. (Intro ends) Jamie Turner, 32 with MBA, started his first job at Wolf River which sellspaper products. He soon became product manager and then senior product manager in three years. He was really successful in Wolf River, but applying same procedures repeatedly made him feel like stagnating and Turner started wanting to challenge himself with autonomy. Looking for a challenge, Turner finds a position at Lambowland.com, a new Internet-based sports shop company. Blinded by new challenges that he sought and benefits such...

...1. How did Turner get himself into this particular predicament? Solution: The following reasons form the root cause of Turner being so indecisive about his position at MLI towards the end of the case: Firstly, Jamie Turner earlier worked at Wolf River, where departments such as control, budgeting, planning and similar tasks were well supported. When he was allowed autonomy and was all on his own, he could not get enough time to prepare himself for all the challenges that were posed for his position and he ended making hasty decisions based on his prior experience. Secondly, his differences with Cardullo regarding their views on the cash flow problem, pricing halogen bulbs below the break-even point with reduced margins, and their other arguments left Turner in distaste and anger. Turner’s strategy of reducing production cost and lesser margins did not go well with Cardullo who wanted higher margins for his products. Moreover, Turner was initially indecisive about joining MLI given the financial situation of the company and other complexities that a merger had created. Also, he was not really keen to go into industrial marketing. He did not weigh the positives and negatives completely before accepting the offer at MLI and started repenting his decision after just a few months into the company. All these things along with the problem of dealing with Julie Chin, lead to this particular predicament. 2. What did Pat Cardullo and Jamie Turner each initially bring to the situation...

...EVO X HID HEADLAMP BLACK-OUT HOW TO: So it was a humid 95 degree day here in Pittsburgh and it's too hot to do much. So I decided I would black out my HID headlights before I swapped them out with my halogens on my GSR. There are a few write-ups on here on how this is done, but none are very detailed. Below is a how-to which began around 11am this morning and will finish tomorrow morning after these are popped back in the oven to reseal…. Tools Required Performix Plastidip Spray Can ~ $8 from Home Depot VHT Night Shades ~ $6 from Pep Boys **optional** Philips Head Screw driver & Flat Head Screw driver 10mm socket using ¼” ratchet0 Home Oven, Cookie Sheet, Moist Towel, Gloves Clamps to hold together when resealing 1) Remove every wiring harness and connector on the rear of the headlight unit. These are all highlighted in green boxes. The ballast itself does NOT get removed from the bottom; it will be fine in the oven. Just disconnect the cable running to it. The metal bracket that holds your main harnesses gets removed entirely, it’s held on with two screws. Also remove the screws on the front of the headlight and also the big metal clip using a flat head screw driver carefully. 2) Preheat oven to 200 degrees. Once preheated, place your headlamp on the moist towel that is sitting on your cookie sheet. Set your timer for 30 minutes. Others have tried 20-25 minutes. This is simply not enough, you’ll end up putting it back in anyways, so just leave it in for 30...

...Halogen bonding, XB, is the product of a non-covalent interaction between a halogen X and a negative site B (e.g., Lewis base). The halogen, X, is usually part of an R-X molecule where R can be another halogen, an organic or an inorganic electron-donating-group. Halogen bonding (XB) is in some ways analogous to hydrogen bonding (HB). In the latter, a hydrogen atom is shared between an atom, group or molecule that “donates” and another that “accepts” it.[1-3] In halogen bonding, it is a halogen atom X that is shared between a donor R and an acceptor Y. Thus the two forms of interaction can be illustrated by: HB : R_H…Y XB : R_X…Y Because of their high electronegativity; halogen atoms in halo-organics are classically considered as sites of high...

...INTRODUCTION Haloalkanes or also known as alkyl halides or halogenoalkanes are organic compound in which one or more hydrogen atoms of an alkane have been subtitued by halogen atoms (F,Cl, Br, I) We can also assume that haloalkanes as halogen derivative of alkanes. Monohalo derivatives have the general formula, C_n H_(2n+1) X, or RX where R represents the alkyl group and X represents the halogen atom. Members of the haloalkane homologous series have the functional group C ---- R They are a subset of the general class of halocarbons. Haloalkanes are widely used commercially and, consequently, are known under many chemical and commercial names. They are used as flame retardants, fire extinguishants, refrigerants, propellants, solvents, and pharmaceuticals. Haloalkanes can be produce from alkanes, alcohols. Alkenes and carboxylic acids. Haloalkanes are reactive towards nucleophiles. They are polar molecules, the carbon to which the halogen is attached is slightly electropositive where the halogen is slightly electronegative. This results in an electron deficient (electrophilic) carbon which, inevitably, attracts nucleophiles. Nucleophiles are Lewis bases where it is electron donor. Nucleophiles are negative ions or molecules that have lone pair...

...prints. A study was made to measure the benefits and costs of using LED lights instead of traditional halogen lamps. RISKS OF LIGHTING HISTORIC PHOTOGRAPHS All lighting harms photographs. (Lavedrine 2003) It is the task of the conservator to minimize this harm so that the photographs can be viewed for a significant span of time, typically 50 to 100 years. For these reasons, historical photographs are displayed only periodically in rooms with significantly reduced lighting. These practices minimize the visitor experience and according to Hunt, reducing light levels diminishes color saturation and contrast. (Hunt 1952, 192) In all lighting systems, ultraviolet light (UV) must be eliminated as that spectrum harms photographs the most. Halogen lights must have UV filters installed which adds to their cost and effectiveness. LED lamps do not emit UV light and do not need extra filters. According to a study by the Getty Conservation Institute, fading from LED lamps does not result in any more damage than conventional halogen lamps with ultraviolet filtering. They found that it is likely using LED lamps results in less fading of photographic materials. (Druzik and Miller 2011) METHODOLOGY In the new exhibit, 12 watt PAR38 20° lamps were utilized. The temperature rating for these lamps was 2700 Kelvin. Although the LED light output was significantly less than traditional halogen lamps, some screening was still needed.
