Chemistry Essay

In these calculations, the formula: pKa = -log Ka is used, where pKa is equal to “the negative log of the acid dissociation constant, Ka”. (Volland, 2005) The use of HCL in the solution is evidence of the need to balance the pH levels of Clonidine when using the drug in intravenous or intramuscular injections in the patient for treatment.The shelf life of the oral Clonidine Hydrochloride tablets and the Clonidine HCL solution for IM & IV injections can be taken to be determinant on the

Chromium toxicities are found in at least 1,306 of the 1,591 sites in the NPL list. Chromium pollution is indeed a major problem today due to rapid increase in industrial and commercial processes that do not comply with international environmental standards. There are many ways chromium toxicities can harm human, animals or plant life. Chromium exposure acquired through dermal route that can lead to contact dermatitis and skin lesions. There is an evident of involvement of chromium

Odor in the environment and between renewable and non-renewable energy resources, renewable energy resources prove to be the chief source of good fuel. Algae-based biofuels for instance may constitute a renewable alternative fuel used extensively in generating electricity. Aside from the renewably extracted geothermal energy, biomass, hydroelectric energy, solar, and wind powers, good fuel alternatives are also available as bioalcohols, ammonia, vegetable oil, hydrogen, non-fossil

Substances held together by ionic bonds are called ionic compounds. An ionic bond is formed when ions of opposite charges (positive and negative charges) attract, such as when an atom of sodium encounters an atom of chlorine. When these two atoms meet, one electron of sodium is transferred to chlorine, creating charged species in the process.

What Does Serotonin Do? The following figure shows the serotonin pathways through brain.The primary function of serotonin is to transmit nerve impulses across nerve cells and neurons. It should be noted that neurons is responsible for raw data from different parts of body organs to the brain. Again, after processing the information brain gives instructions to body organs through the same neuron. In short, neuron activity is important in keeping all bodily activities intact. When variations

The most common form is the 500 mg tablet though other formulations such as suspensions and suppositories also exist (Acetaminophen n. Paracetamol is quickly taken in from the gastrointestinal tract and attains peak plasma concentrations in about an hour (Acetaminophen n. The cytochrome P450 system metabolises it into N-acetyl-p-benzoquinamine (NAPQI), a toxin that is entirely detoxified through conjugation with glutathione and excreted. Paracetamol is a fairly safe drug. However, doses greater

The assay is comprised of two parts which are the preparation of standard solutions and obtaining a calibration graph, and analysis of paracetamol tablets. For the first part, paracetamol is weighed into a beaker and dissolved in deionized water. This is done in a 1-L volumetric flask where the deionized water is added up to the mark. A specific volume of the resultant solution from the flask is taken and diluted to about 10 times the original volume taken. This solution is the stock solution

Organic carbonates are used in the manufacture of a large number of other industrially important products, mainly polyurethanes and polycarbonates. They are employed in the manufacture of pharmaceutical products, herbicides, pesticides, electrolytic fluids, polyimide films, etc., in addition to being used as solvents and fuel additives (3). They are environmentally benign, they are replacing toxic organic solvents, methylating agents and carbonating agents such as methyl halides, dimethyl

Glycogenolysis occurs in muscle cells when there is an immediate requirement for energy; it also occurs in the liver when there are low levels of blood glucose. Pancreatic alpha cells release glucagon so that glucose enters cells slowly, thus there is an increase in breakdown of glycogen in the liver. Gluconeogenesis, which mainly occurs in the liver, is the pathway for producing glucose from non-carbohydrates molecules, such as lactate, amino acids and glycerol (Stephen et al.Blood glucose

Stirrer was turned on, the current shot up a few mille-Amperes and then started depreciating even with the stirrer still on at a similar rate to when the stirrer was off. This caused the electrolyte solution to become more uniform for a short while, which improved the current circulation.The main effect of any form of corrosion is the deteriorative loss of a metal. These sentiments are echoed by Callister (2007), who defines corrosion as a process by which there is a deteriorative loss as a

Is that CO2 is the only component that will be absorbed by water, so the amount of methane that comes out of the absorption tower will be the same as the amount of methane comes into the tower. The CO2 absorbed by water cant be obtained from the mixture for commercial purposes. Based on this situation, product revenue can be determined by multiplication of the price of each product by the number of moles of methane in the feed. (Shown in Table 1.The 1” Rashig rings, or the packing material,

Some of the sources of proteins include: meat, poultry, seafood, beans, peas, eggs, processed soy products, nuts which are usually derived from plants or animals. Notably, they are described according to their functions in the human body e. actin is used for structural component by providing support and structure to the cells which allows the body to move. Immunoglobulin, a type of protein, acts as an antibody by biding itself to various specific foreign bodies in the human being such as virus

Moreover, it has increased confidence of both patients and health professionals towards a possibility of overcoming the deleterious disease.Essentially, the ability of amperometric glucose sensors to determine accurately the level of concentration of blood glucose has caused a revolution in health care. Accurate determination of glucose levels within the blood has lead to improved health services within the community. The foremost importance of amperometric glucose sensors relates to

 The crude oil first undergoes a fractional distillation process. One of the fractions called naphtha is the important element for the production of plastic. The two main processes that are used for the production of plastic are polycondensation and polymerization.
