Background: Cumberland Metal Industries (CMI) was one of the largest manufacturers of curled metal products in the country.Their sales grew from $250‚000 in 1963 to over 18‚500‚000 by 1979.It originally custom fabricated components for chemical process filtration and other highly technical applications. The company’s philosophy soon evolved from selling the metal as a finished product to selling products that used it as a raw material . Earlier CMI used to sell exaust gas recirculation(EGR) valves

EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled

Acid Rain Acid rain occurs when Sulphur Dioxide (SO2) is released into the atmosphere by electricity generation‚ motor vehicles‚ factories and by wildfires and volcanoes. Once released‚ the sulphur dioxide reacts with water to produce sulphuric acid. This has a pH of approximately 2-3 pH. This has a dramatic effect on water dwelling wildlife. Most water dwelling creatures can’t withstand water more acidic than pH 5. This causes the mass loss of life of animals such as trout‚ perch‚ frogs and mayflies

CHAPTER 1 Introduction Background of the Study Like many other hygiene convenience‚ shoe polish or can also be called boot polish is usually a wax ‚ cream or paste used by people to shine‚ water proof and restore the appearance of leather shoes. This extends the footwear’s life. This is made up of many kinds of chemicals and because of this; it can cause irritations‚ allergies to us. In our generation‚ shoe polish is used every day and companies produce a lot of it to meet the demands of

Preparation of an Ionic Compound from Aluminum Metal October 6‚ 2010 The purpose of this laboratory project was threefold‚ in that it presented three main objectives. The first objective was to prepare the ionic compound alum from aluminum powder. The alum was produced from the reduction-oxidation reaction of aluminum with potassium hydroxide and sulfuric acid in water. The second objective was to then analyze the alum product for water crystallization; that is‚ to determine the value of x in

effect of heavy metals lead and cadmium (0.05 mM and 0.3 mM) on growth and antioxidant enzymes of seedlings of 2 mung bean genotypes (NM 19-19 and Azri mung-2006). Results revealed that germination percentage and seedling length decreased when compared with the control for both genotypes. However‚ seedling length and germination percentage was better in NM 19-19 as compared to Azri mung-2006. Elevated levels of protein were observed under metal stress in both genotypes. Heavy metals induced oxidative

How to Remove Heavy Metal Toxins with Oral Chelation Do you currently have heavy metal toxins damaging the inside of your body? The answer is unfortunately "yes" for over 99% of us! So what is a “heavy metal” and what do I need to know? If you’re thinking of Ozzy Osbourne‚ KISS‚ or Ted Nugent‚ you’re not alone. The truth is that most people do not fully understand the real dangers of heavy metal poisons and just how common they are in our modern world. Fortunately‚ you can take steps to understand
