Fun Facts about Polypropylene: In 2013, the global market for polypropylene was around 55 million metric tons. Invented in 1954 by Giulio Natta of Milan, Italy It can be represented by this symbol: Objects made of polypropylene Electric cables Food packaging Plastic bottles Carpet backing Corrugated boards Structure of Polypropylene Chemical Formula: (C3H6)n Polypropylene is a polymer* with a crystalline structure. - For the crystalline region, many monomer propylene will bond together…

Nutrients and Health Providing appropriate sustenance supplies the body with essential materials for biological processes. A calorie-controlled diet including a variety of nutrient dense foods from each major food group sets the framework for optimal health. By following recommendations set by the United States Food and Drug Administration (USDA), individuals can promote fitness and reduce disease. Adequate daily intakes of macronutrients, vitamins, and minerals through healthy food sources is…

Literature Review Temperature The greatest source of heat in water is solar irradiance by direct absorption (Wetzel and Likens, 2000). We might assumed that heat will remain at where it was absorbed and temperature will decrease exponentially with depth, just with the light and may remain constant at the hypolimnion (Lampert and Sommer, 2007). Water has the properties of high heat capacity, thus the larger lake might tends to moderate the local climate and provide the longer growing season for…

In recent years, policymakers and medical experts have expressed alarm about the common incidence of the genetic disorder sickle cell all over the world. While most parties agree that the issue deserves attention, consensus revolves around how to respond to the problem. This review paper examines the disorder, sickle cell, its signs and symptoms, mode of transmission and treatment methods. The information gathered for this paper was obtained from the work of various researchers and their…

Unknown Scheme: You can use this scheme as a guide when you are making your own. Don't just show up to class with this though. **SCHEME FOR UKNOWN 2:** Unknown Scheme: 2 I. Description A) Phase, solubility, color, odor, shape II. Flame Test A) Orange flame  Na+ present (possibly K+, NH4+) B) Red flame  Ca2+ present (no Na+) C) Purple flame  K+ present (possibly NH4+) D) No change in flame color  Ca2+, K+, Na+ absent (possibly NH4 present) III. pH Test A) Add a little…

Alison Crist 10/18/15 Period 6 In order to maintain homeostasis, cells must produce energy by allowing the necessary nutrients into the organelles while eliminating wastes that could be harmful to them. The cell membrane is also known as the phospholipid bilayer because of the fact that there are two layers formed by phospholipid molecules. The phospholipid has a phosphate and a lipid portion. "The phospholipids lie with their hydrophilic heads at the membrane surface and their hydrophobic…

extraction method and the acid-base reaction technique. Using the acid-base reaction technique, the acid and base are neutralized, producing salt and water. By using the liquid-liquid extraction method, two different liquids were isolated based on their solubility in two liquids. Following that, and using the procedures in the instructions reference below, 2.9 mg of benzoic acid were recovered, with a percent recovery of 5.9% and a melting point range of 120.7 oC- 124.1 oC. 30 mg benzocaine were…

and stomach acid has a pH of approximately 2. The purpose of this investigation is to discover whether the pH of a solution will affect the time needed to dissolve the ibuprofen. Hypothesis If the pH of a liquid is increases, then the solubility rate of Ibuprofen will decrease because acidic liquid breaks down Ibuprofen at a quicker pace. This means that vinegar should dissolve the pill at the fastest rate and the soap water should dissolve it at the slowest rate.…

employed technique for this purpose is called chromatography. 1 There are many different types of chromatography, including gas-liquid, paper, column and so on. 1 Chromatography differentiates by allowing the differences in polarity, vapor pressure, solubility and so on of different substances to be observed. 1 In our endeavor, we will be using specific types of chromatography, termed Thin-Layer Chromatography (TLC) and column chromatography. Essentially, TLC is an adsorption aspect of…

Outgassing of carbon dioxide (CO2) from inland waters has been estimated to offset approximately 20% of net uptake of carbon into the terrestrial biosphere. However, this calculation is based on estimates of source strength at the air-water interface that is highly uncertain [Ciais et al., 2013]. One of the largest unknowns is the accuracy and precision of freshwater partial pressure of CO2 (pCO2) estimates. To better understand observational uncertainty in CO2 flux from inland waters, here we…
