world coal reserves according to the type of coal and the potential use. Figure 1: World Coal Reserves according to type of coal and potential use (World Coal Association) Coal is mainly used in power generation and metallurgical applications with majority of the coal being produced by Teck Coal Limited being used in the manufacture of steel. Derived from vegetable matter that has undergone the process of coalification, coal is a combustible sedimentary rock which releases energy upon combustion.
CHAPTER 1 INTRODUCTION Urinalysis is a commonly used clinical tool for the evaluation of various renal and non-renal problems (endocrine,metabolic and genetic) (Lee 2009). Urinalysis is the third major diagnostic screening test in the clinical laboratory, only preceded by serum/plasma chemistry profiles and complete blood count analysis (Delanghe & Speeckaert 2014). A routine urinalysis is done as a screening test during many hospital admissions and initial physician visits. It is also performed
Hengen, Joe Wahl, Colleen Strom, Nicole D Introduction: Chemical interactions can often lead to the production of environmentally unsafe byproducts. If the byproducts have no use, they are disposed as waste. Waste disposal companies make profit by collecting and disposing large amounts of these unused byproducts. These companies often concentrate the byproduct solutions so that they are easier to dispose of. One particular chemical waste disposal company wishes to utilize these concentrated byproduct
with limiting reagent analysis. The reaction of Copper (II) Sulfate, CuSO4, mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was found to be 2.1726g which meant that through limiting reagent analysis Fe was determined to be the limiting reagent and the chemical reaction was
the metal selectivity, chelating agents offer certain advantages over conventional mineral processing reagents even from the synthesis point of view. With the major donor .atoms-S, N, 0 and, to some extent, P-numerous possibilities exist to tailor make reagents for specific applications.[1-3] For polymers the backbone offers further possibilities for the incorporation of the required properties. In general, the choice of a chelating agent or a group is made on the basis of its function in well-known
which is a Grignard reagent, and benzaldehyde which is a carbonyl group. The goal of this experiment was to investigate the ability of the Grignard reaction to yield the theoretical predicted product and evaluate its efficiency. The Grignard reaction is an important reaction because of its ability to allow the formation of carbon-carbon bonds. These formations of C-C sigma bonds, then allow for the formation or making of large or complex synthetic molecules from very simple reagents. These complex molecules
are the chemicals used to maintain the pool and the type of maintenance. A traditional pool uses chlorine tablets, sticks, or granules. “The active ingredient in 3” tablets, 1” tablets and sticks is called “Trichlor” (or Thrichloro-S-Triazinetrione), and the active ingredient in granular chlorine is called “Dichlor” (or Sodium Dichloro-S-Triazinetrione)” (Clark Guide to Swimming Pool Maintenance pg 7). These chemicals are used to rid that water from germs and algae. Both of these chemicals are very
by electrolyzing a mixture of potassium fluoride and hydrogen fluoride. CaF 2 is the major fluorine source for the fluorine industry. Fluorine has interested the chemistry and pharmaceutical community since its discovery on account of its special properties such as small size, high electronegativity, and low polarisability.  The length of the C-F bond is almost the same as the length as the C-H bond (1.39 and 1.09 Å, respectively)  . Therefore, introduction

Among the several metal nano particles gold (Au) nanoparticles have attracted rigorous consideration for their numerous applications in catalytic , sensing, imaging, diagnostics [3-6], tunable surface Plasmon resonance, surface enhanced Raman scattering, electrical, magnetic, thermal conductivity chemical and
