The objective of this lab was to brominate a hydrocarbon by converting 2,3-dimethyl butane to 2,3-dibromo-2,3-dimethyl-butane through crystallization. In order to verify the purity and the identity of the product two tests were done, one was using melting point and the other was NMR. The melting point range found in this test was between 138°C-175°C, whereas the ideal melting point for the product was 168°C. Based off of the melting point range, it can be assumed that the product had formed…

Introduction Filtration is a passive process in which solutes pass through a membrane from high pressure to low pressure. The amounts of solutes that pass through the membrane are dependent upon the amount of pressure and the size of the membranous pores. Solutes such as blood cells and proteins are too large to pass through so capillaries retain them. An example of filtration in the body is renal filtration, a process in which the blood is filtered in the kidney so that substances that are…

Fracking Should Be Outlawed in The United States. Fracking? What on Earth is that? Well, hydraulic fracturing, or the so-called fracking, is the process of drilling down into the Earth, then using high pressure water to break open the rocks, to release the natural gas inside, but there’s a problem. Water, sand, and chemicals are also injected along with high pressured water into the rocks. The gas comes right out of the head of the fracking well, but where do the chemicals and…

accurate melting point can be taken, leading to a more precise identification of a compound. The overarching goal was to isolate and identify three different unknowns in a given sample using these techniques. There are two types of extractions; solid-liquid extractions involve extracting a soluble compound from an insoluble (solid) material…

This experiment was conducted to practice a variety of techniques in organic chemistry: separation, mechanisms, acid-base reactions, evaporation, recrystallization, and identification. The goal of this experiment was to identify the unknown mixture of two compounds. The two compounds were separated first by altering the acid components solubility through deprotonation, and then protonating the acid component again to form the separated precipitate. The ether in the neutral layer was evaporated,…

The Effects of Cryotherapy on Recovery Student’s Name Institution The Effects of Cryotherapy on Recovery Introduction It was proved by modern medicine that using of cold provides healing of the human body. Local cryotherapy as cold application has become one of the directions of physiotherapy. Currently, the information concerning cryotherapy is abundantly available. Therefore, the main goal of this work is precise and direct research on the effects of cryotherapy and…

basically anybody could build." There are obvious reasons why the Russian government and the US government and any other world governments would want to supress the knowlege of torsion field technology. First of all, let's be absolutely clear. This technology is not entirely benevolent. There are extraordinarily damaging and destructive things that can be done with it also it would be the end of their power, the ones possesing this technology. How do we transition to this next thing without…

eye just like wearing a spectacle or a helmet and he or she will be looking into the HMD which will have two small displays with lenses and semi-transparent mirrors. The display of the HMD may have different type of screen which may include LCDs , Liquid crystal on silicon , OLED , CRT and some may even have multiple display in it to…

Migraines are real medical conditions just like diabetes and asthma. It is not just a headache. Migraines are severe, excruciating headaches, but are known to be a serious concern. There is no exact cause to migraine headaches, but some major effects that can cause them are bad posture, flashes of light, nausea or vomiting, and increased sensitivity to light. Stress is another major cause of migraines. But, there are many different types of migraines. Although, the employer has the duty to…

The Differences Between Laptops and Tablets In this day and age, it is difficult to not find someone interacting with technology in some form, whether this is a phone, tablet, computer, ipod, etc. In fact, this has become a part of daily life recently, and most adults have their own personal device to either communicate, work, or relax on. Tablets and computers play a large part in these daily occurrences as well, but what’s the right device to use? Is it just a work computer? Or something…
