Dow Chemical Case Question 1 Polyethylene is the world’s most widely used plastic. Polyethylene plastic’s principal application was in packaging‚ from trash bags to milk jugs. It was widely used in the manufacture of everything from trash bags‚ picnic cutlery and garbage pails‚ to plastic toys. Polyethylene also replaced glass‚ wood‚ and metal in certain applications. There were three types of polyethylene‚ Low-density polyethylene‚ High density polyethylene and Low linear density polyethylene

Question 1 Issues Arising From Case The issues are the future viability of the plant for producing EPC and the long-term effects of not upgrading this production line. The additional upgrade will result in additional production‚ but as mentioned by the sales director if there is no demand for the increase in supply and Rotterdam plants excess will be added to the Mersey side quantities the plant upgrade could ultimately result in a dropping of prices to shift supply. The transport division is also

Liquids & Solids Pre Lab Questions: 3pts 1. What are the learning goals of this lab? The learning goal of this experiment is to view and experience the melting point and boiling point of different substances. 2. Why is acetamide not allowed in contact with your skin? What precautions does one have to take to work with this chemical? Acetamide is a carcinogen‚ which can cause cancer. Therefore‚ it should not be allowed to come in contact with a person’s skin. Any person working with this chemical

Chemical Banks – Allocation of Profits Question 1. How will you resolve the due bill controversy? Due Bill Controversy: Metro Division’s service to sell the Due Bill for the Treasury division is not recognized by the Treasury department. While Metro acted like a cost center‚ Treasury acted as profit center. When Metro Bank division reviewed the profit loss statement for the Due Bills‚ it was found that Metro division was incurring loss of $26.50 for each transaction. Consequences of Due

Chapter 1: Introduction Chapter 1: Introduction Ionic liquids (ILs) can be viewed as a new and remarkable class of solvent. They are also a type of materials that have a long and useful history‚ where the earliest material that meets the current definition of IL was observed in the mid-19th century when a separate liquid phase called the “red oil” was observed in Friedel-Crafts reaction [17]. Over the following years‚ there has been a rapid growing of interest in ILs due to the realization

of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof hot-plate‚ and one using a rotovap. III. Theory Fig. 1a+1b. Figure 1a shows how water and oil separate in the separatory funnel‚ while figure 1b shows the actual apparatus. Liquid-Liquid extraction is a versatile and dependable

Task 3: The chemical tests used in order to carry out and collect these results are useful for the simple identification of colourless organic liquids and ones that are often found at the scenes of crime. The first test carried out was the Lucas test which was used to identify a variety of alcohols following the contribution of a given solution‚ from carrying this out I could then identify that primary and secondary alcohols were present with one tertiary alcohol also being present however despite

Date of Experiment October 7‚ 2012 Report Submitted: October 7‚ 2012 Title: Liquids and Solids Purpose: The purpose of this experiment is to determine the boiling point of liquids and the melting point of solids. Procedure: I got all of my materials together and set up. I poured rubbing alcohol in a beaker and rubber banded it with the thermometer. I logged the last bubble that came out of the capillary tubes. After that I crushed the acetamide and carefully put it in the capillary tube

Liquid Nitrogen Liquid nitrogen is nitrogen in a liquid state at a very low temperature. Its chemical formula is N2. Manufacturing of Liquid Nitrogen Liquid nitrogen is made by cooling and compressing air straight from the atmosphere. The type used to produce large amounts of liquid nitrogen looks vastly different but really happens is that air squashed and cooled . When you squash it‚ air molecules are forced closer together. If you also cool it down the molecules can slow down enough to
