BONDS Bonds pay fixed coupon (interest) payments at fixed intervals (usually every six months) and pay the par value at maturity. Par value = $1‚000 Coupon = 6.5% or par value per year‚ or $65 per year ($32.50 every six months). Maturity = 28 years (matures in 2032). Issued by AT&T. Types of Bonds Debentures - unsecured bonds. Subordinated debentures - unsecured “junior” debt. Mortgage bonds - secured bonds. Zeros - bonds that pay only par value at maturity; no coupons. Junk bonds - speculative or

Bonds is something that retains and holds on together with one another. There are three major chemical bonds and they are‚ Ionic‚ Covalent‚ and Hydrogen bonds. An example of a covalent bond would be SCl^2 which is Sulfur dichloride. SCl^2 is a covalent bond because since they are close to each other in valence electrons‚ they have almost full outer shells so they share electrons with one another. A good example is table salt NaCl‚ because they are on opposite sides of the periodic table therefore

molecule with covalent bond o Formula unit with ionic bond * Molecules: formed by covalent bonds * Lattice energy is the energy released in the formation of an ionic compound. DEFINITION: The formation of an IONIC BOND is the result of the transfer of one or more electrons from a metal onto a non-metal. Characteristics of both bonds: * Occur between 2 atoms * Composed of 2 electrons * Have both ionic and covalent characteristics * Together = 100% * Both bonds are measured

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
