What are Yield to Maturity (YTM) and Yield to Call (YTC)? By calculating the present and future value of bonds‚ managers can make sound decisions about their potential strengths and weaknesses as investments. Answer the following questions in this week’s Discussion 2 thread: 1. What terms (or inputs) are needed to calculate yield to maturity (YTM)? How does this compare to calculating yield to call (YTC)? To calculate the YTM you will need to use Annual Interest‚ Par value‚ Market Price

THE CHEMISTRY OF ORGANIC MOLECULES I. MACROMOLECULES-large molecules that are composed of smaller molecules and atoms that are bonded together. These are among the largest of all chemical molecules. A. Polymers-the largest of the macromolecules. These are composed of numerous‚ small identical subunits known as Monomers. There are 4 major polymers that are important for living organisms. These polymers are; carbohydrates‚ lipids‚ proteins and nucleic acids. B. Polymers

electron shells) will have a greater atomic size. An atom with more electron shells is said to have an increased shielding. Example: Potassium (K) is larger than hydrogen (H). This is because potassium has 4 electron shells‚ whereas hydrogen only has 1 electron shell. An alternate way of explaining potassium’s larger size is to say‚ “Potassium has a greater shielding than hydrogen”. The period trend for atomic size is that it decreases across the periodic table‚ from left to right. Sodium is larger

Experiment 1: Preparation of 1-Bromobutane and Reactivity of Alkyl Halides Objective: The purpose of this lab is to prepare 1-bromobutane from 1-butanol in an acid-catalyzed substitution reaction. While the reaction would be expected to occur as SN2 due to the primary nature of the substrate‚ because H2SO4 is used as a solvent‚ the conditions are very polar and the reaction can proceed via an SN1 reaction. The main objective is to obtain test results to determine the mechanism of the reaction

Use this packet and your book to answer the questions throughout this packet. Organic Nomenclature - Alkanes‚ Alkenes‚ Alkynes Naming organic compounds can be a challenge to any chemist at any level. Historically‚ chemists developed names for new compounds without any systematic guidelines. In this century‚ the need for standardization was recognized. For simple molecules‚ the nomenclature system worked out by the International Union of Pure and Applied Chemists (IUPAC) works well. For complex

hydrocarbons INTRODUCTION: organic chemistry Organic chemistry is the chemistry of compounds that contain carbon and hydrogen. The element carbon has a special role in chemistry because it bonds with other carbon atoms to give a vast array of molecules. The varity of molecules is so great that we find organic compounds in many common products we use‚ such as gasoline‚ medicines‚ shampoos‚ plastic bottles‚ and perfumes. The food we eat is composed of different organic compounds that supply us with

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

Chemistry Revision F331 Isotopes - atoms with the same atomic number‚ but different mass numbers 131I - radioactive tracer for thyroid. 99Tc for tumours. Radioisotopes - gamma emitters & short half life - long enough to detect‚ but not long enough for damage. Beta particles emitters are more useful than alpha particle emitters because they penetrate more and so are more easily detected. Also‚ less damaging. The half life is the time taken for half the isotope to decay Mass left = initial
