Clonidine/Quinapril
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

Chemistry and the environment: an essay about the properties of the atmosphere and what makes a good fuel.
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

Chemical Properties between a Mixture and a Compound
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.

Colourimetric Assay for Paracetamol
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

Clinical biochemistry lab report
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

Corrosion lab ( paraphrasing)
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.
