Polyvinyl Chloride Lab Report

355 Words2 Pages

Polyvinyl chloride is obtained by chain polymerization. Double bonds of vinyl chloride monomer get opened up. Since monomers possess a double bond between two of their carbon atoms in their structures, those get activated in the presence of tiny concentrations of starters. In this way, double bonds get open and monomers react rapidly so they associate with each other by forming macromolecules chains. Polyvinyl chloride polymerization is a highly exothermic reaction, where a high amount of heat is broken away (1525 kJ/kg). This reaction is shown below: n C2H3Cl  (-C2H3Cl-) n As it could be observed in previous reaction, the only product that is formed in this stage is suspension PVC, whose medium size goes from 50 to 200 microns. Suspension

    From the data obtained in Tables 1-3, we were able to plot multiple graphs using excel. These graphs give a better representation of the data as seen in Figures 1-9. It can be seen that each figure shows a slight increase in CO2 production, which signifies a possible change in metabolic rate. Figures 4 and 7 show a relatively large change between the control and fox urine. The changes in slope between theses two are 0.0267 for Figure 4’s slopes and 0.0192 for Figure 7’s slopes.

    Suppose you need to find the fractional European call and the fractional European put options. Let the Hurst parameter be $H=0.85$, the $\sigma=0,25$, $r=0.10$, $S_{fbm} = 100$, $K = 95$, we have \begin{eqnarray*} d_1^{fBm} & = & \frac{\ln{\frac{S}{K}} + \frac{1}{2}(r( T - t) + \frac{(1)\sigma^2{( T^{2H} - t^{2H})}}{2})}{\sigma{\sqrt{T^{2H} - t^{2H}}}}\\ & = & \frac{\ln(\frac{105}{100}) + (0.10(0.25 -0) + \frac{(1){0.25^2}{0.25^{2(0.85)} - (1)0.25^{2(0.85)}}}{2}}{(0.25){\sqrt{0.25^{2(0.85)} - 0}})} \end{eqnarray*} we obtain $d^{fBm}_1= 1.0558$. We find in the normal distribution that $N(1.0558)= 0.8544$ and $N(-1.0558) = 0.1456.$

    The purpose of this report is determine if sodium chloride is a viable option as a deicer on winter roads. To determine this, one must compare a multitude of factors. In this lab, the freezing point depression of water, enthalpy of dissolution, cost, and environmental impact will be discussed. A large factor in how effective a substance is as a deicer is it’s ability to decrease the freezing point of water. If the freezing point of water can be lowered, the outside temperature must be much colder to reach this new freezing point, resulting in less ice on the roads.

    The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

    Transformations Presented in E. Coli Using the pGlo Gene Introduction In biology, genetic transformations involve the transfer of a gene into an organism to give that organism a new gene to express (Blaber, 2004). Genetic transformations can be used for therapy, vaccinations, and in tissue renewal (Rivera,2014). In 1928, a man named Frederick Griffith discovered the term genetic transformations and their use (Griffiths,2000). To test these new genetic transformations a substance called pGlo is used to allow for replication and to see the results because of the bioluminescence.

    As seen in table 1, the theoretical yield was .712 g of C_17 H_19 NO_3. The % yield of this experiment was 7.51 % of C_17 H_19 NO_3. . This low yield can be explained from a poor recrystallization technique combined with potential contamination. Throughout the experiment, the mixture changed color from green, orange, to yellowish lime, and eventually clear.

    INTRODUCTION A gas chromatograph (GC) can be utilized to analyze the contents of a sample quantitatively or in certain circumstances also qualitatively. In the case of preparative chromatography, a pure compound can be extracted from a mixture. The principle of gas chromatography can be explained as following: A micro syringe is used to inject a known volume of vaporous or liquid analyte into the head or entrance of a column whereby a stream of an inert gas acts a carrier (mobile phase). The column acts as a separator of individual or chemically similar components.

    Equal parts of both monomers are combined with water in a reactor. This mixture is then crystallised to make nylon salt, which has specifically stoichiometric equivalents. The nylon salt formed then goes into a reaction vessel which is where the polymerisation process takes place in either in batches or continuously. Removing water drives the reaction n HOOC-(CH2)4-COOH + n H2N-(CH2)6-NH2 → [-OC-( CH2)4-CO-NH-(CH2)6-NH-] n + 2n H2O to polymerisation through the acid and amine functions forming amide bonds.

CaCO3, commonly referred to as limestone, is an organic substance and is, in a sense, the crystallised “carbonic salt” of the element, calcium2. In addition to being a salt, the pH level of Calcium Carbonate is 9.91, and it is therefore, a basic substance, due to the fact that it is comprised of a pH level higher than 7, which is neutral3. HCl, however, is the bodily acid found in the stomach of human beings.

    Abstract The unknown concentration of benzoic acid used when titrated with standardized 0.1031M NaOH and the solubility was calculated at two different temperatures (20◦C and 30◦C). With the aid of the Van’t Hoff equation, the enthalpy of solution of benzoic acid at those temperatures was determined as 10.82 KJ. This compares well with the value of 10.27KJ found in the literature.
