water is gas emissions: “The energy required to manufacture and transport the bottles to market severely depletes our supplies of fossil fuels and adds to greenhouse gas emissions” (Natural Life‚ 2007‚ p. 10). The plastic that makes up bottles‚ polyethylene terephthalate (PET)‚ is made from oil and generates more than 100 times the toxic emissions than other plastics. It takes 15 million barrels of oil per year to make all the plastic water bottles in the United States‚ which diminishes available

The Equilibrium Constant of an Ester Hydrolysis Reaction Julia Stanley CHM 152 LL Dr. Asmita Kane Budruk Goal of the lab: The purpose of this laboratory is to determine the equilibrium constant‚ Kc‚ for the acid-catalyzed reaction between an unknown ester and water to produce an unknown alcohol and an unknown carboxylic acid. I was using Unknown Ester #3 with a density of 0.9342 and Molar Mass of 74.08 g/mol; alcohol with density 0.7914 and Molar Mass 32.04 g/mol. Chemical

Candy‚ specifically sugar candy‚ is a confection made from a concentrated solution of sugar in water‚ to which flavorings and colorants are added. Candies come in numerous colors and varieties and have a long history in popular culture. The Middle English word candy began to be used in the late 13th century‚ coming into English from the Old French çucre candi‚ derived in turn from Persian Qand and Qandi‚ "cane sugar"‚ probably derived from Sanskrit word khanda "piece "‚ perhaps from Dravidian

1. INTRODUCTIONmcDonald¶s‚ the leader in the fast-food wars‚ faced a crossroads in the early 1990s. Domestically‚ sales and revenues were flattening as competitors like Burger King‚ Wendy¶s‚ and Taco Bell encountered new challenges Sonic and Rally¶s competed using a back-to-basics approach of quickly serving up burgers‚ just burgers‚ for timeless consumers. McDonald¶s was gathering flak from environmentalists who decried all the litter and solid waste its restaurants generated each day To counter

SOLVENT EXTRACTION Solvent extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up

BREAKDOWN IN SOLID DIELECTRIC The requirements of good dielectric: o Low dielectric loss‚ o High mechanical strength‚ o Free from gaseous inclusions‚ and moisture‚ o Resistant to thermal and chemical deterioration. Solid dielectrics have higher breakdown strength compared to liquids and gases. When breakdown occurs‚ solids get permanently damaged while gases fully and liquids partly recover their dielectric strength. Breakdown mechanism varies depending

when heated towards the liquid state. In this wider sense‚ glasses can be made of quite different classes of materials: metallic alloys‚ ionic melts‚ aqueous solutions‚ molecular liquids‚ and polymers. Of these‚ polymer glasses (acrylic glass‚ polyethylene terephthalate) are the most important; for many applications (bottles‚ eyewear) they are a lighter alternative to traditional silica glasses. Glasses play an essential role in science and industry. Their chemical‚ physical‚ and in particular optical
