Hydrofracking is a process used by oil companies to capture resources on domestic soil. It uses various methods to extract methane mostly. Controversies are around the issue because of its many pros and cons. I believe that the cons outweigh the pros in the long run and fracking should be avoided. Hydrofracking is a way of extracting methane from rocks like shale. It uses chemicals and water under high pressure to crack these rocks that contain the wanted gas. Methane is a molecule with…

The consumption of bottled water has been significantly increased. Many people in the country today take bottled water and they do not consider its consequences. Bottled water has negative effects on the environment and people’s health. The movie “Tapped” shows the dangers of taking bottled water. It takes a close look at the bottled water industry and notes that the companies involved are not taking enough measures to reduce the negative effect that their activities have on the industry. Many…

Introduction In 1950 the Nobel Prize for Chemistry was awarded to Otto Diels and Kurt Alder for their description of an invaluable chemical reaction (The Nobel Prize in Chemistry 1950). The reaction they described was for the formation of carbon-carbon bonds in a six membered ring with exceptional control of its stereochemistry in one step (Diels-Alder Reaction Gains Nobel Prize). This was an important discovery due to the fact that six membered rings are abundant natural products and man-made…

distinct smell, thus concluding that the compound is ionic. The solubility tests indicated that the compound was soluble in water, NaOH, and HCl and non-soluble in acetone and toluene as shown in Table 1. The compound was soluble in water indicating that the compound is either polar or ionic, but not soluble in toluene or acetone eliminating it being polar or nonpolar, making our compound ionic. The compound was also soluble in both NaOH and HCl, which are contradicting because a compound…

INTRODUCTION The Love Canal episode is one of the major and most publicized environmental disaster recorded in America history. In recent time, it has been described as an epidemic. It became a focus of intensive and extensive studies on health effect, environmental studies and epidemiologic research (Friis and Seller, 2014, p.20; Jasanoff, 1998 p.83). This paper attempts to bring to light how a community is forced to bear the consequences of decision made by greedy and negligent corporate…

We were further interested to elaborate our catalytic conditions to the Friedel-Crafts reaction of indoles with α-amido sulfone 8 as a precursor of N-Boc α-imino ethyl glyoxylate. The use of imino derivatives of glyoxylates as electrophiles in aza-Friedel–Crafts reaction afforded the corresponding 3-indolyl glycine derivatives, an important class of nonproteinogenic amino acids useful for synthetic intermediates and building blocks for natural products such as dragmacidins.[14] Although some…

The employees in Vietnam were being exposed to a toxic adhesive named toluene. Toluene has been found to cause harmful effects among workers who are not properly guarded from the poison and the fume that it emits. The laws protecting the workers are ignored in favour of cutting costs and lowering health standards. This is possible…

In this lab, two methods of distillation (simple and fractional) were utilized to separate a mixture of volatile compounds (cyclohexane and toluene). As a first observation of the results and data generated, looking specifically at the simple and fractional distillation curves, it seemed that the fractional curve obtained was not as expected. In fact, it was not very different from the simple distillation curve, having a gradual positive slope. This means that there was actually not a big…

These are the household items that anyone can purchase. Industrial chemicals such as chloroform, toluene, benzene, methanol, coolants, paints, glues, and gases. These are the most dangerous, even to a first-time user. The general method of consuming solvents is called “huffing”. Initially, blood levels peak, dizziness, disorientation, light-headedness…

Since 2013, there was a wide variability in e-cigarette product engineering, including: nicotine concentrations in e-liquids, variable volumes of e-liquids in the product, different carrier compounds (propylene glycol with or without glycerin), different additives, flavors, and battery voltage. Instead of burning tobacco in conventional cigarette to release smoke that contains nicotine, users of e-cigarettes will heat a nicotine liquid and convert the liquid to a vapor then inhale it. Depending…
