Title of Experiment 12: The Effect of Ionic Strength on the solubility of an Electrolyte Aim: The purpose of this experiment was to determine the thermodynamics variable of enthalpy‚ ∆H for the dissolution reaction of boric acid in water. The solubility of boric acid was measured over a range of various temperatures by finding out at what temperature crystallization began for solution of different molarities. A graphical relationship between the natural logarithm of molal concentration and the inverse

stocks and bonds which can be a sign of the company’s financial standing in a market. Since investors are risk averse and they would not like to put their money on stocks and bonds of a struggling company‚ but they would like to put their money on stocks and bonds of a stable and a progressing company. Investors benefit from company’s profit in the form of dividend when they buy a company’s stocks and investors can get higher or lower yield based on the bonds. This is the rationale behind bonds’ and stocks’

In the financial markets‚ the most common forms of marketable securities are stocks and bonds. Though they have some similarities to each other‚ they differ greatly in many aspects. Broadly speaking‚ both financial instruments enable one to invest in corporations‚ public and/or private‚ with possible profitable returns in the future. Stocks (or shares)‚ by definition‚ are shares of ownership in a company. By purchasing stocks in a company‚ the investor becomes a part owner‚ and thereby owns a percentage

the wooden originals. The temples had painted decorations and low-pitched wooden roofs. Columns had ornamental capitals—the top of the column—in one of three designs. The simplest‚ Doric‚ consisted of columns with plain molded capitals and no base. Ionic capitals were decorated with a pair of scrolls‚ known as volutes. Corinthian capitals‚ the most ornate‚ were decorated with an inverted bell-shaped arrangement of leaves. Prime examples include the Parthenon and Erectheum‚ in Athens. From 100 B.C

OF IAN FLEMING’S JAMES BOND- WITH REFERENCE TO ‘FROM RUSSIA WITH LOVE’. From Russia‚ with Love is the fifth novel in Ian Fleming ’s James Bond series‚ first published in the UK by Jonathan Cape on 8 April 1957. As with the first four books‚ From Russia‚ with Love was generally well received by the critics. The story was written at Fleming ’s Golden eye estate in Jamaica in early 1956. By the time the book was published‚ he did not know whether he wanted to write another Bond book or not. The story

Building materials of a cell are composed of two atoms that form molecules. A chemical bond is created when two atoms share an electron. Also called covalent bond because they share valence electrons. A covalent bond‚ which is the strongest bond‚ takes action when two atoms valence overlap. For example‚ there are two suns and the light that shines from the two solid spheres forms many rays making a radiant cloud around each of the two. If these suns move closer together the radiant shine would
