August 15‚ 2012 COMPOUND MICROSCOPE A compound microscope is an optical instrument used to see objects that are too small for the naked eye. A compound microscope is a microscope fitted with two or more convex lenses. The high magnification produced by these lenses together enables a detailed study of micro-organisms‚ cells and tissues. These types of microscopes are therefore widely used in scientific and medical research. The basic design of a compound light microscope consists

Abstract: When ionic compounds are dissolved in water‚ they break apart into ions. In this lab the opportunity to mix two ionic solutions and observe the results was given. Some ions will remain dissolved and uncombined in the solution even when they are mixed with other ions. When other ions are mixed‚ they form compounds that appear as cloudy or grainy precipitates. The objective of this lab was to observe the formation of compounds and to write the names and formulas of ionic compounds. It is also to

The percent yield of meso-1‚2-dibromo-1‚2-diphenylethane was calculated to be 66.36% and with a melting point of 235.1°C. Therefore‚ it can be concluded that this experiment was successfully conducted as the percent yield obtained is only 33.64% off from the equilibrium point‚ and because the melting point met the literature value. The percent yield for the product was less than 100%‚ indicating that were experimental errors‚ such as an undesirable side reaction‚ or more likely‚ an incomplete reaction

COORDINATION COMPOUNDS: * FLEXIDENTATE CHARACTER OF POLYDENTATE LIGANDS; * Poly dentate ligands have flexi dentate character in the sense that all donors atoms may not form coordinate bonds with the central metal atom or ion. For example; EDTA which is the hexa dentate ligand also acts as tetra dentate or penta dentate in certain complexes. Similarly sulphate ion‚ which is a bi dentate ligand‚ also acts as a mono dentate ligand in certain complexes‚ e.g. in [Co(SO4)(NH3)5]Cl. * LABILE

Original Composition While the cancerous fumes entered my lungs‚ the life threatening chemicals made me feel relaxingly calm‚ so I continued anyways. That was when I was still a kid‚ a fourteen year old nicotine addict‚ presently I am sixteen. I still remember those days in the past. Sometimes I used to question myself‚ “When will this addiction cease?” I have never obtained an answer to that question‚ until recently‚ when I experienced the loss of my best friend. The cause of death was from second-hand

P2 2. Judy Johnson is choosing between investing in two Treasury securities that mature in five years and have par values of $1‚000. One is a Treasury note paying an annual coupon of 5.06 percent. The other is a TIPS which pays 3 percent interest annually. a. If inflation remains constant at 2 percent annually over the next five years‚ what will be Judy’s annual interest income from the TIPS bond? From the Treasury note? b. How much interest will Judy receive over the five years from the
