Museums are a perfect way to represent what history has unfolded for the public’s eye. Consideration needs to be made when a person is shopping for fragments of history such as arts or artifacts. A main consideration is profit; however‚ there are consequences if the museums does not make enough money. If a museum does not make enough money‚ this could suggest that people are not interested in taking tours throughout the museums anymore‚the new age of technology is taking over. What happens after

Purpose: To synthesize 1‚2‚3‚4-tetraphenylnaphthalene through a two-step synthesis. The aldol condensation reaction between benzil and dibenzyl ketone forms 2‚3‚4‚5-tetraphenylcyclopentadienone‚ which then reacts with a benzene formed by anthranilic acid and isoamyl nitrate in order to yield 1‚2‚3‚4-tetraphenylnaphthalene. Reaction Equation A: Synthesis of 2‚3‚4‚5-tetraphenylcyclopentadienone: A solution of 4 capsules potassium hydroxide (0.5g) and 5mL anhydrous ethanol was prepared

ARTICLE: NEW GREEN TECHNOLOGY AND ITS BENEFIT 1.0 INTRODUCTION Malaysian must put a ‘price’ on carbon‚ set regulations and pour money into research and development and let Malaysian ingenuity meet the market force for clean energy. This strategy would not only help the world avoid the worst of climate change‚ it will end our dependence on hostile foreign regimes that we rely for oil. Everything that we would actually do in response to climate change would make us healthier as a country

The Strings‚ the Grass‚ and the Vessel Life is very complex and often hard to define. However‚ this challenge does not stop people from trying to sum up the meaning of life in one word. In Paper Towns by John Green‚ the three metaphors the strings‚ the grass‚ and the vessel are used throughout the book to chronicle the protagonist’s‚ Quentin‚ experiences. The novel revolves around Quentin Jacobsen‚ a high school senior. When his former best friend and long time crush‚ Margo Roth Spiegelman‚ comes

of MPTP dramatically accelerates this process in the course of days and not years (Hanson et al.‚ 2015). Additionally consumption results in a reduction of glutathione content (Sian et al.‚ 1999). What have been good and bad consequences of the synthesis of MPTP? MPTP negatively affects the body by penetrating the blood-brain barrier and entering the brain cells. MPTP is not toxic‚ however when it oxidizes it forms MPP+ which is toxic. Toxic oxidation later reaches the extracellular fluid and

Although the Muji shark fin soup cannot sell in Hong Kong and Taiwan in Asia‚ we still can buy it in Japan and we all know the number of sharks is decreasing sharply. Therefore‚ we suggest that Muji should substitute the real shark fin buy some other food which has the similar texture and taste‚ just like the artificial shark fin made of edible gelatin‚ in order to reduce the number of deaths of sharks because their shark fin have to make into food. Also‚ we suggest that Muji can motivate and sponsor

Synthesis of Acetanilide By: Rick Whitely April 9‚ 2013 Organic Chemistry Lab 1; Professor J. Hutchison Recrystallization is a common method of purifying organic substances through the differences in solubility at different temperature. In this experiment‚ acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heated water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes

phenomenal creatures called aliens? The most UFOistic meaning that you have described is “an extraterrestrial intelligent being‚ someone who lives on other planets out from Earth.” (DeVore 4) With this I can agree‚ until you begin to depict an alien as a green monster with two fingers‚ three eyes‚ and the motives to take over our world. You both explain in this article that there is absolutely no way anyone or anything can live in our universe. While I can respect your theories and opinions‚ I can’t help

The purpose of this experiment is to synthesize isopentyl ester by an esterification reaction between a carboxylic acid and an ester. Carboxylic esters‚ like isopentyl acetate‚ are normally used to create artificial flavors. In the preparation of isopentyl acetate‚ esterification of acetic acid and isopentyl alcohol occurs. Esterification is an equilibrium shift to the product side using an excess of one of the starting components. In this experiment‚ the excess reagent is acetic acid because it
