Synthesis Of Ethylene Dichloride

1. Which reactants used in this experiment are flammable? Discuss the safety precautions that are necessary when working with flammable materials in the lab?

In order to show you why these students believe the mystery mixture is a combinations of NaHCO3 & C6H8O7 I will need to show you the mixture’s chemical and physical properties. The NaHCO3 & C6H8O7 mixture is a bright white color, and has a slight airy smell. The claim also has a powdery white substance or the NaHCO3. It also has small white spheres, that resemble the mystery mixture’s, which is probably the C6H8O7. The students have also learned through experimentation that if you leave the

Found on Celebrity Airlines Flight 82181 were a number of substances brought on by passengers. Given that the crash was ruled a terrorist attack, identification of all substances found on and in the bodies and luggages of the victims needed to be made. To do this, empirical and molecular formulas were put into use when determining substance identities. Each substance was tested to find the percent composition of carbon, hydrogen, nitrogen, and oxygen, and then used to find the empirical formula of the substance by using 100 grams of each substance to represent 100% made up by the elements combined. The mass of each element in the substance calculated from the percent was then divided by the molar mass of that

The atom of an element has electrons that are found around the nucleus in regions known as orbitals. When energy is absorbed by the electrons of an atom they begin to jump to higher energy levels. When this happens the electrons are in an excited state. However when the electrons begin to release the energy and drop in energy levels they emit electromagnetic radiation. If the radiation that is emitted falls between 400 to 700 nanometers then the electrons emit photons which we can see as visible light.

In order to properly dispose of this unknown substance, several tests needed to be performed in order to identify the substance. A flame test, pH test, and conductivity test are used to narrow the identity of the compound. After identifying the compound, its identity needs to be proven by a flame test, pH test, and conductivity test. Afterword, one gram of the unknown compound needs to be synthesized. It was determined that the most likely identity for the unknown compound was either Ca(NO3)2, CaCl2, or CaCO3.

In the first part of the experiment (identifying the chemical makeup of the unknown compound

They ruled this combination out by comparing its physical and chemical properties to those of the mystery mixture. One of the differences between the mystery mixture and the mixture of MgSO4, C6H8O7, and NaHCO3 is during the chemical reaction. During the reaction of the mystery mixture the bubbles and only about one centimeter high. During the reaction of MgSO4, C6H8O7, and NaHCO3, the bubbles were approximately one inch tall. Another difference during the chemical reaction was the time that the two mixtures fizzed. The mystery mixture fizzed for about 3 minutes and 14 seconds. The combination of MgSO4, C6H8O7, and NaHCO3 fizzed for approximately 5 minutes and 47 seconds. Thirdly, the eighth-grade scientists decided to eliminate MgSO4, C6H8O7, and NaHCO3 as a possibility to be the mystery mixture because during the reaction the mystery mixture's temperature was 16.5oC at the end of the reaction. While the combination of MgSO4, C6H8O7, and NaHCO3 ended up at 17.6oC. Finally, the scientist knew that they could rule out the mixture of MgSO4, C6H8O7, and NaHCO3 is because they noticed that the chunks in the mystery mixture were not shiny, but very dull, and the lumps in the mix of MgSO4, C6H8O7, and NaHCO3

Their goal is to limiting the exposure to firefighters and first responders to these cancer causing toxins. The chemicals outlined in the submitted language of LC182 are defined as  "Flame-retardant chemical" means a chemical or chemical compound for which a functional use is to resist or inhibit the spread of fire. "Flame-retardant chemical" includes, but is not limited to, halogenate, phosphorus-based, nitrogen-based and nanoscale flame retardants and any chemical or chemic compound for which "flame retardant" appears on the substance safety data sheet required under Code of Federal Regulations, Section 1910.1200(g) (2015).

While this particular incident is slightly outside of my community, I found it very interesting upon observing recent rail shipments and noticed the rather common nature of this item’s movement.  I then researched the chemical

I did some research about the explosion, and found the answer to why it happened. This demonstration is called the “whoosh bottle.” It is where you place a low-boiling alcohol such as methanol, ethanol, or isopropanol into a bottle, coat the entire bottle with the alcohol, and then use fire to create an combustion reaction

This means that unknown compound A was cyclohexanol and it produced the product cyclohexanone. This was able to be found through the IR of the alcohol, the product, and fingerprint spectra all matching the samples

Distillation. Transfer the clear liquid to a dry 25-mL round-bottom flask using a Pasteur pipet. Add a boiling stone and distill the crude t-pentyl chloride in a dry apparatus. Collect the pure t-pentyl chloride in a receiver cooled in ice. Collect the material that boils between 78°C and 84°C. Weigh the product and calculate the percentage yield.

Hickey) Organic chemistry lab 2 manual, department of Chemistry University of New Orleans. We observed a yellow residue in the bottom of the flask after the dichloromethane has been boiled off, and 2-propanol (3ml) was added to it and then was heated until the entire residue dissolved and the solution was transferred to a clean Erlenmeyer flask.

Ethanoyl anhydride and concentrated sulfuric acid are highly corrosive. Ethanol is flammable, salicylic acid is irritant to eyes and skin. Chemicals were handled in the fume cupboard. Plastic gloves were worn throughout the experiment.

The evolution of ACC also brings about the production of 5¢-methylthioadenosine-nine. Increase in the rate of respiration of the fruit gives ATP (Adenosine triphosphate) need for the methionine cycle and can lead to induced ethylene production without high levels of intracellular methionine. SAM is a crucial methyl giver and relates to numerous aspects of cellular metabolism. Thus, the two steps involved in the synthesis of ethylene is the formation of ACC and its conversion into ethylene. The genes encoding ACS and ACO have therefore been studied more deeply than other enzymes in the pathway, although there is proof that a few other genes concerned with methionine synthesis and methionine salvage pathway are differentially demonstrated throughout ripening and in response to ethylene (Alba and others 2005; Zegzouti and others 1999). ACS and ACO are encoded by multigene families in higher plants, with tomato having at most nine ACS (LEACS1A, LEACS1B, and LEACS2-8) and five ACO (LEACO1-5) genes (Barry and others 1996; Nakatsuka and others 1998; Oetiker and others 1997; Van-der-Hoeven and others 2002; Zarembinski and Theologis 1994). Expression survey has disclosed that at least four ACS (LEACS1A, LEACS2, LEACS4, LEACS6) and three ACO (LEACO1, LEACO3, LEACO4) genes are differentially shown in tomato fruit (Barry and others 1996, 2000; Nakatsuka and others 1998; Rottmann and others 1991). LEACO1, LEACO3, andLEACO4 are shown at low levels in green fruits that are in the first
