Jeanine Azzo Chemistry 1412 Professor Chaka April 15‚ 2014 Group 10-9 Solubility‚ Kidney Stones‚ CSI Pre-Lab Objective To conduct an experiments to determine solubility of ionic compounds in different solute-solute and solvent solute interactions. Description We will be mixing ionic compounds in solute-solute and solvent solute interactions. We will be combining sodium‚ potassium‚ calcium‚ magnesium‚ copper‚ iron‚ nickel and silver and some anions like chloride‚ sulfate‚ nitrate

BOND PROBLEM SOLUTIONS 1. Six years ago‚ The Corzine Company sold a 20-year bond issue with a 14 percent annual coupon rate and a 9 percent call premium. Today‚ Corzine called the bonds. The bonds originally were sold at their face value of $1‚000. Compute the realized rate of return for investors who purchased the bonds when they were issued and who surrender them today in exchange for the call price. PV = 1000; N = 6; PMT = 140; FV = 1090; CPT I/Y I/Y = 15.02% 2. You just purchased

Bonds and Their Valuation After reading this chapter‚ students should be able to: • List the four main classifications of bonds and differentiate among them. • Identify the key characteristics common to all bonds. • Calculate the value of a bond with annual or semiannual interest payments. • Explain why the market value of an outstanding fixed-rate bond will fall when interest rates rise on new bonds of equal risk‚ or vice versa. • Calculate the current yield

Nupoor Matieda October 10‚ 2014 PD 9/10 Lab Report Separation of a Mixture of Sand and Salt Goal(s): To separate a mixture of sand and salt and to find the percent of each component by mass of each mixture Background Theory: A mixture is a combination of two or more pure substances in which each pure substance retains its individual chemical properties. Mixtures can be separated by physical processes such as filtration and evaporation. Filtration is a process where solids

How do ionic compounds form? How do electrons change the shape of a molecule? These are just a couple of the questions that this paper will answer. How do ionic compounds form? Ionic compounds are formed by positive and negative ions. An ionic bond means that there are valence electrons being shared between the two molecules. This can cause the molecule to become negative or positively charged. An ionic compound is formed by the complete transfer of electrons from a metal to a nonmetal and the

No Sugar No Sugar (1986)‚ a play exploring the treatment of Aboriginal people in the 1930’s‚ was written by Jack Davis‚ an Aboriginal Western Australian who grew up in Yarloop and the Moore River Settlement. No Sugar is told from the point of view of an Aboriginal family who are coerced into living at an Aboriginal reserve because the white people in their community didn’t like them living close to them. The authority at the settlement are very abusive creating conflict between the Millimurra family

FOOD LAB Title Food Lab Abstract The aim of this report is to see if the any of the four food apple sauce‚ carrot juice‚ cracker juice‚ and turkey juice contain protein‚ starch‚ or sugar. Between these four foods two are positive for sugar which are apple sauce and carrot juice. Sugar is an organic molecule of carbohydrate and so is starch. The starch was positive in two of the foods which are cracker juice and carrot juice. Protein is its own organic molecule and only one food tested positive

Using present value to value bonds A bond‚ from the perspective of the person issuing the bond is a form of long term debt. In the hands of the person who has acquired the bond it is an asset. The agency issuing the bond agrees to pay a fixed sum of money to the holder of the bond for a period of years and then‚ at the end of that period‚ to pay back the face value of the bond. Bonds can be issued by a variety of agencies/companies: 1. Municipal bonds: issued by cities‚ states and

Vicente Viloria CHM 130 LL Section 22258 Lab 12: Introduction to pH‚ Household Products and Buffers 12/9/14 Introduction In this experiment the students will be determining the pH of household products along with other solutions using several different indicators as well as a pH meter. The experiment also has the student determining what the buffer solution is in an aqueous solution. The student will also be testing the pH of milk of magnesia and will see how it affects the stomach acid. Lastly

The purpose of this experiment was to investigate the relationship between mass‚ frequency‚ bond strength. Using the Infrared Spectroscopy‚computer simulations‚ and spring stiffness provided with evidence that validated the experiment. The first set of test focused on how the mass of certain molecules affect vibrational frequency. Table A1. shows two different masses with two different frequency. A spring stiffness of 85 g/cm was used with a mass of 430.31g showing a frequency of 60(s/1) . Using
