agar-water gel containing three wells. Drops of potassium permanganate (KMnO4)‚ potassium dichromate (K2Cr2O7) and methylene blue(C16H18N3SCl) were simultaneously introduced to each well. Methylene blue‚ having the largest molecular weight‚ displayed the smallest diameter (11 mm) and diffused at the slowest rate (0.20 mm/min.). Next is potassium dichromate with a diameter of 24 mm and rate of diffusion of 0.30 mm/min.. The fastest is the potassium permanganate with 19 mm diameter and diffusion rate

mechanisms of crystal growth is called crystallization or solidification. Potassium alum (Aluminum Potassium Sulfate) is the white crystalline natural mineral salt (double sulfate) of potassium which typically occurs as encrustations on rocks in areas of weathering and oxidation of sulfide minerals and potassium-bearing minerals. The crystal alum mineral is commercially extracted in select quarries throughout the world. Potassium alum is specific chemical compound that is also part of a class of alum

granular fertilizer is in a slow-release formula. A numbering system is used to define the percentages of the three essential plant nutrients. For example‚ a 20-20-10 fertilizer would contain 20 percent nitrogen‚ 20 percent phosphorus and 10 percent potassium. Secondary nutrients and trace elements are typically listed.Henan Daswell Machinery Co.‚ Ltd‚is a professional manufacturer and trader specializing in the research‚ development and production of construction machinery for nearly 30 years.

What is the most significant abnormality shown in the serum chemistry? -The most significant abnormality is a rise in the Potassium levels. The reason this is the most significant is because of the narrow physiologic range. What abnormality is shown in the EKG? -There are “peaked” or “tented” T waves. The T wave represents the repolarization of the ventricles which is normally demonstrates soft gradual rise following the QRS complex‚ however in this case the t wave is not properly formed.

Data/Results: Part A: In the potassium iodide solution‚ I think there were potassium atoms as well as iodine atoms. In the lead nitrate solution‚ I think there were lead and nitrate ions. The potassium atoms and the lead atoms can be classified as cations‚ since they are metals. The iodine atoms and the nitrate ion can be classified as anions since they are nonmetals

Bacon‚ Toast‚ Sodium Nitrate and Potassium Bromate For Breakfast Samuel Martino Have you ever looked at the ingredients on the side of a food package? There is a lot more than the main food in the package. Usually it has real food then several different chemical compounds and preservatives listed behind the real stuff. In some foods the ingredients include chemical compounds as sodium nitrate and potassium bromate. Sodium nitrite is an ionic compound and is identified by the chemical formula

cell is not stimulated‚ the membrane is known to be polarized. For a neuron to be polarized‚ it is by maintaining excess of sodium ions on the outside of the cell and excess potassium ions on the inner part of the cell. A volume of sodium ions and potassium ions usually leaks through its channel but the sodium ions and potassium ions pumps on the membrane that restores the (k+) back inside and Na+ back outside. Resting potential: once the neuron is no longer active‚ unstimulated‚ polarized it is known

(Kevin J. Martin‚* Esther A. Gonza´lez‚* and Eduardo Slatopolsky†‚ 2009) The major consequence of hypomagnesaemia is hypokalaemia. Hypokalaemia is commonly seen in hypomagnesemic patients due to the underlying disorders that induce both magnesium and potassium loss. For example‚ diuretic therapy and diarrhoea normally increases

mostly of sucrose with molten potassium chloride‚ a violent reaction occurs. A surprising amount of energy us released by the reactant‚ and in process‚ the atom and molecule rapidly rearrange to form 3 products(CO2/H2O and KCl). This reaction is said to be products favor. A favoured product reaction is where almost all of the reactants‚ react to form products. In this case its sucrose and potassium chlorate react completely to form carbon dioxide‚ water and potassium chloride. This reaction is exothermic
