Aspirin is used to lessen the fever and relieve mild to moderate pain from conditions such as muscle aches, toothaches, common cold and headaches. In conditions such as arthritis, it may also be used to reduce or suppress the pain and swelling. Aspirin is known as a salicylate and also a nonsteroidal anti-inflammatory drug (NSAID). The (IUPAC) name of Aspirin is 2-(acetyloxy) benzoic acid. It is pronounced as Acetyl Salicylic acid.The route of administration is usually oral The biological half life
experiment was to mix calcium chloride, sodium bicarbonate, water and phenol red, and observe the changes, but also determine which chemicals caused which reaction. Some important parts of this experiment are the scientific method and the fact that chemistry is the study of matter. These things are important because they help the examiner focus on the things that will most effitiontly help them figure their experiment out, but still give them some wiggle room to add in their own opinions. The scientific
As the natural fibers result from the chemistry of cell wall components, modification of the chemistry of cell wall polymers can change the basic properties of a fiber. The chemicals to be used for chemical modification must be capable of reacting with lignocellulosic hydroxyls under neutral, mild alkaline, or acidic conditions
Abstract An Air Dehumidifier can be designed and modeled working on simple principle of dehumidification of compressed air by means of collision with the number of cylinders arranged in series. This dehumidifier will not require any hygroscopic media or absorptive media such as Activated Alumina, Silica gel, Salt tablets, etc. which are used in other dehumidifiers. It does not require any refrigerant which is used in the refrigerated dehumidifier. The designed dehumidifier will be most reliable
Cleaning water has always been a challenge for human beings when it came to removing certain substances like fine grains or crude oil for example. New research, however, comes from a chemical engineering team at Rice University and shows that there is a catalyst that works perfectly for obviating toxic nitrates out of water. In cleaning water and keeping it clean, some challenges have brought people to try to keep waters separate using graphene. This new study comes not long after expert chemists
What is chemical engineering? Chemical engineering is only a small part of engineering that uses chemistry, physics, biochemistry, economics and applied mathematics to make, change, move and correctly use chemicals. Chemical engineers play major roles in different fields of engineering, they also have a huge impact on society and the products we use and consume. Many great schools offer chemical engineering as a major or just as an area of study. The list of schools include: Arizona State University
1. ABSTRACT In all precipitation reactions, the ions of one substance are exchanged with the ions of another substance when their aqueous solutions are mixed. At least one of the products formed is insoluble in water. Two ionic compounds exchange ions. Reaction will not occur unless one of the products either precipitates, or is water. Dissociation, Ionic compounds – Metal + nonmetal (Type I & II) – Metal + polyatomic anion – Polyatomic cation + anion , Dissociation: when ionic compounds dissolve
DLLME procedure For DLLME, 5 mL of phosphate buffer saline (pH 7.4) containing 500 µL acetonitrile (disperser solvent), 500 µL NaNO3 10% (w/v) and 2.5 ng AFs stock, was placed in a 10 mL screw cap glass test tube with a conical bottom. Then 170 µL of chloroform (extracting solvent) was rapidly injected into the sample solution using a 500 µL syringe resulting in a cloudy solution. The aflatoxins were extracted into the fine droplets of CHCl3. The solution was then centrifuged at 5000 rpm for 3 min
Our personal view of the world comprises of the way we think, our beliefs, and what we discern as true and false. Every new theory introduces information, and in that, presents another way of viewing the world. If a group of individuals perceive a theory in a similar manner, this can create a shared understanding. In this way, every theory has the potential to solidify and destabilize our worldview. Solidification suggests filling gaps in the existing body knowledge, and eventually helping to enhance
How was Avogadro’s number determined? Jessica Kim 12D Starting from 200 years ago, scientists tried to figure out the basic ideas of chemistry. One of them they put lots of effort in was to find out the mass of the smallest particle, mole. Measuring the mass was a primary difficulty at that time since one mole of a substance was unable to weigh without using developed technology. Even though, it was clear that everything was made out of a small unit, there was no evidence that could determine
