Antifreeze Fluids With Ibps Lab Report
4.2 Antifreeze Fluids with IBPs As studies show in Dow Chemical Company (DCC), the glycerol-water solution becomes slushy when it freezes (107) indicated with our studies shown in Figure 41(a). Specifically, the experiment shows the interaction between 20% glycerol and IBPs. For example, at 274.2 K the right-side peak becomes shorter because it reaches its freezing point of the 20% glycerol at 268.5K (83). Then, when the temperature is lowered to 241.1 K, the inhomogeneity of the system due to the glycerol is observed. Studies from DCC has shown that when lowering the temperature, the slush becomes increasingly viscous (107). As shown in Figure 41(a-b), the interaction between glycerol and the protein is detected by the different line-shape
Cold Water Lab
630 Words | 3 PagesIntroduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.
Molar Mass Of Unknown # 43 Using The Derived Freezing Point Depression
1294 Words | 6 PagesPurpose: The purpose of this experiment was to determine the molar mass of unknown #43 using the derived freezing point depression. To obtain the freezing point depression, t-butyl alcohol was placed in a cold-water bath and frozen solid for a total of two runs. Then, unknown #43 was dissolved in t-butyl alcohol and placed in a cold-water bath until frozen solid. This process was repeated for a total of three runs, with the first two runs containing half of the unknown, and the last run containing the full amount of unknown.

Serum 2216 Lab Report
592 Words | 3 PagesMacromolecule test 1 differs from the second chart by testing non-reducing sugars in the first test and proteins in the second. In depth the lab required to heat the sample at times, mix them, and add them to a warm water bath of 100 Celsius. The following graphs were obtained by following the guidelines within the
Dry Ice Research Paper
380 Words | 2 PagesSo what is dry ice? As known dry ice is made from carbon dioxide gas. So in particular, it’s actually just solid blocks of carbon dioxide turning into a gas. Now that’s something! As far as we thought, it could have been just blocks of ice blown by a flamethrower.
Propylene Glycol Research Paper
529 Words | 3 PagesPropylene Glycol Propylene Glycol is found in antifreeze, it is a humectant which means it is hydrating but is also a skin irritant. It is widely found in skin care products such as body washes, deodorants, shampoo, conditioner and liquid for e-cigarettes. This is because it is cheaper for companies to add this to their products rather than using botanical ingredients. By adding Propylene Glycol it prevents the product from spoiling in hot and cold temperature and helps products to sink into the skin. Although Propylene Glycolic can work into the blood stream.
Freezing Point Lab Report
1227 Words | 5 PagesWhen the freezing point depression is higher, the freezing point of the solution will be lower. Conclusion: All in all, the freezing point was used to determine the molecular weight of the unknown solid. The experiment was successful except to one error in trail two. In trail two, the temperature never plateaued making the calculations for molecular weight not accurate.
D-Xylitol Lab Report
855 Words | 4 PagesMain reason on why PPP has been the only focusing pathway in this experiment is because the pathway that will produce xylitol in E. coli contain in PPP only. As stated by [10, 21], PPP is
Nucleophilic Substitution Reactions Lab
1039 Words | 5 PagesThe data table provided below obtained melting point data for crude product, pure product, and mixture of the pure and 4-tert-butylbenzyl. 12. The TLC data obtained is provided in a table below. The TLC data was conducted solely in a 9:1 hexane/ethyl acetate solvent solution as opposed to the 1:1 and pure hexane solution as well. This was due to the lack of time, but as explained in number 7, a very polar solvent (1:1 solution) or non-polar solvent (pure hexane) is not ideal when obtaining
How Does Glycerol Concentration Affect Mag Formation
1094 Words | 5 PagesAlso the MAG formation was in between 35-52% and FA formation was less as compared to DAG giving ratios same as obtained during glycerolysis reaction. There can be two possibilities, one may be that at high glycerol concentration more amount of water is required for reducing the DAG formation or other may be that at high glycerol concentration water has no effect on glycerolysis. It was seen that, as the water concentration increased, conversion of TAG increased. Formation of MAG and FA also increased while formation of DAG
Dry Ice Research Paper
337 Words | 2 PagesDry ice is made from raw carbon dioxide gas. Dry ice is the cold dense white mist produced by solid carbon dioxide in the air, used for theatrical effects. Dry ice is called dry ice because it doesn’t melt into a liquid. Dry goes from solid to gas instead of solid to liquid. Dry ice is useful for keeping things frozen.
Dry Ice Research Paper
479 Words | 2 PagesIt's cold and you hear creeps of footsteps around the corner. It's dark and the atmosphere is damp. You feel something touch your back but when you look back all you see is the flickers of a dark green light a few feet away and white fog arising from the ground. “FIRE!?”
Water Hydration Lab Report
603 Words | 3 PagesIntroduction: In this lab, of water in a hydrate, or a substance whose crystalline structure is bound to water molecules by weak bonds, is determined by heating up a small sample of it. By heating, the water of hydration, or bound water, is removed, leaving only what is called an anhydrous compound. Based on the percent water in the hydrate, it can be classified as one of three types: BaCl2O ⋅ 2H20, with a percent water of about 14.57%, CuSO4
Research Paper Endoplasmic Reticulum
3186 Words | 13 PagesThe process called protein quality control happened in the endoplasmic reticulum. This process is careful monitor to bind a sophisticated a quality control system[16]. The goal of this system is to identify and disjoint any proteins that are potentially problematic. And this appeared to be a critical process especially for multicellular microorganism that have a very long lifespan because if there is any defecation process the accumulation of misfolded protein would be accumulate to a detrimental level that impair of the wild ability of the organism. Because of that, quite often even wild type of proteins can be mistreated as misfolded of protein and get degraded and this simply because they make folds just a little slowly or entered to unfold
Ice Water Experiment
1071 Words | 5 PagesHeissmeyer was discovered in 1959 working in his TB clinic in East Germany. At his trial, he said: "For me there was no basic difference between human beings and guinea pigs”.25 At Dachau from August 1942 to May 1943 freezing experiments were conducted for the benefit of the German Air Force. 26 The experiments were done to investigate how to treat people severely chilled or frozen. Two types of experiments were done; the first were by ice water and the second were dry land experiments.27The ice water experiments were to test how to rewarm pilots who crashed into the sea and the dry land experiments were to test how to rewarm troops fighting in deep snow and freezing temperatures. Walter Neff testified on December 17-18, 1946 the experiment was done in a wooden basin two meters long and wide.
