    INTRODUCTION TO ANTIFREEZE!: Antifreeze is a common chemical product that helps to keep the engines of the car stay cool. It is a combination of the chemical Ethylene glycol or Propylene glycol, which is 50%, and 50% water. Antifreeze is used during the winter & summer, to keep the car engine stay cool and running, and to achieve the freezing and boiling point depression, depending on the weather. Antifreeze allows the engine fuel to fully vaporize and burn better with less transmission. It also

    miles of a major waterway according to the National Resources Defense Council. The major pollutant, a substance called ethylene glycol or propylene glycol, is one of the major substances that are getting into our waterways. Glycol is used for de-icing the airplanes during the winter weather season. At 93 airports during the 1989-1991 timeframe, more than four million gallons of glycol was used for de-icing purposes. With well over 500 certified airports in the United States, the actual amount emitted

    quickly in the 0.9% NaCl plus one drop of saturated soap solution and that in the 0.9 NaCl (standard) solution there would be no hemolysis because it aids in the production of a isotonic environment. We also hypothesized that hemolysis of the 0.3 M ethylene glycol solution would be quick and 0.3 M glycerol and 0.3M glucose solutions would occur much more slowly based on their structure and hydroxyl

  • Physical And Chemical Properties Of Ethylene Glycol (MEG)

    1592 Words  | 4 Pages

    INTRODUCTION Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound with the formula (CH2OH)2. Monoethylene glycol (MEG), also known as ethylene glycol (EG) or simply glycol, is a diol mostly used for the production of polyester fibers and polyethylene terephthalate (PET) resins. It is also used in antifreeze applications and in pharmaceuticals and cosmetics. MEG is conventionally produced through the hydrolysis of ethylene oxide (EO), which itself is obtained via ethylene oxidation.

  • Plant hormones

    1573 Words  | 4 Pages

    Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others, where they are effective in very small amounts. Depending on the target tissue, a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

  • Are Bananas Curved

    1238 Words  | 3 Pages

    Most bananas are curved. Fritz Eichelberger wrote, “Bananas go through a unique process known as negative geotropism…The fruit grows against gravity, giving the banana its familiar curved shape.” (Eichelberger, 2016, para. 1). Fact, bananas are indeed curved based on the unusual way in which they grow by pulling away from gravity. An individual might be inclined to utilize this information and conclude that bananas essentially just grow in the direction of the sun. In reality this statement is really

    Think banana I have always loved bananas, and when we got this assignment, it seemed the most natural to observe my favorite fruit. It was 8:51 AM on Saturday morning when I started observing the banana. I started by being very anxious and tense, worrying about what will I be able to write about my fruit only by looking at it. I don't like writing in general, and this seemed even harder to do, how will I come up with a story about a fruit? As the minutes went by, I got more relaxed and I

  • Polyethylene: Manufacturing Cycle and Environmental Impact

    reaction necessary to separate the ethane, a thermal cracking unit (a sort of long heated tube) i.e. a plug flow reactor is used. After a series of distillations, ethylene exits the tube. Before using ethylene to produce polyethylene, the compound needs to be purified to almost 100%. In order to reach this level of purity the ethylene needs to be freed of olefins, acetylenes, dienes and water through several processes such as: driers are used to take out the water, a demethanizer is used to remove

  • Keeping Bananas Prepare The Longest?

    678 Words  | 2 Pages

    Spoiling Bananas Bananas are a very healthy food to eat, however, you have to eat them quick. Bananas go rotten and spoiled within about a week. Depended upon the type of banana, you could have 3-50 bananas in a bunch. Most bunches that you will find at your local grocery store will have 5-7 bananas. There are many methods to keeping your bananas ripe, but most people do not know which one is the best. So, this experiment will prove which method is the best for keeping bananas ripe the longest.

    faster and there are two ways to do it and they all need ethylene gas to ripen. Let’s start out with trapping ethylene gas is. This is one of the ways to ripen bananas faster (Upton, 2010) and the best thing to use to trap the ethylene gas is using a paper bag. To speed up the process of ripening, put a banana in a paper bag with another fruit such as an apple, pear, tomato, or another banana (Upton, 2010). The paper bag traps the ethylene gas from the banana and the other fruit. Putting a banana

    How Are Chemical Solutions Used In Society? Solutions are homogeneous mixtures. A chemical solution is a combination of a solvent and one or more solutes. The solvent in a solution is the majority of the solution and the solute makes up the rest of the solution. When the solvent and the solute dissolve in each other you end up with a chemical solution. Many chemical reactions are done in solutions, and solutions are also very closely related to our standard everyday lives. For example the air we

    INTRODUCTION Fracking, also known as hydraulic fracturing or hydrofracking, is the process of natural gas extraction from shale (fine grained sedimentary rock) deep within the earth, and considered a relatively new process. Although the technique of fracking has been known since the 1940s, only in the recent decade has there been a fracking boom. The process of fracking begins with a vertically drilled well, which then turns ninety degrees and continues horizontally into the shale rock layer. A mix

    Introduction: Light Olefins such as ethylene and propylene are extremely important chemical intermediates, produced through cracking of various hydrocarbon feeds, which are used to produce a wide range of chemical products, such as various polymers, as well as a wide range of smaller chemicals. After cracking, olefin molecules need to be separated from their corresponding paraffin molecules. The olefins are also important for petrochemical industries due to their use as main building blocks for
