Q1. Peirson: Chapter 5: Questions 2‚ 3‚ 4‚ 5‚ 6‚ 10 and 11. Chapter 5 2. What factors does the required rate of return of a project reflect? Soln: The required rate of a return for a project reflects the rate of return that could be generated by investing in the next best alternative investment. This discount rate reflects the return required by the firm as compensation for having funds tied up in the project. The compensation demanded increases as the uncertainty‚ or risk‚ associated

a 10 year bond that has a face value shs 1000‚ a coupon rate of 6% and pays interest once a year. (a)Suppose person A bought this bond at par when it was initially issued and sold it 1 year later to person B for shs 1024.What is B’s total return? Soln Total return =[ Interest paid +(selling price – buying price)]/buying price Given; Annual interest paid = coupon rate x par value‚ coupon rate = 6%‚ par value =1000. = 6% x1000

Analysis of Hydrocarbons Jessa Grace B. Castillo* and Stephanie Chua Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines ______________________________________________ Hydrocarbons are organic compounds containing only hydrogen and carbons and further divided in major types. Hydrocarbons react differently in reagents. The basis of determining an unknown hydrocarbon is due to the differences in reactions of hydrocarbons. An unknown compound is determined using tests.

CHM152LL LAB MANUAL COMPLEXOMETRIC DETERMINATION OF WATER HARDNESS Complexometric Determination of Water Hardness Introduction Complex ions When a neutral molecule or anion (a Lewis base) donates electron pairs and attaches itself to a metal ion center (a Lewis acid)‚ the resulting cluster‚ or complex‚ of atoms becomes a single complex ion. When such complexes form‚ the electron donating groups (called ligands) form coordinate covalent bonds through empty orbitals on the metal ion. An example

Determination of the Concentration of Acetic Acid in Vinegar Lab Exercise 4 CHEM 1106 9/19/12 Purpose: Standardize a sodium hydroxide solution using a primary standard acid. Determine the molarity and the percent by mass of acetic acid in vinegar by titration with the standardized sodium hydroxide solution. Introduction: Vinegar is a dilute solution containing acetic acid. Since vinegar has a low pH‚ it can be titrated with a base. Titration is a method used in order to ascertain

Identification and Production of Materials ================================ Ethene‚ Polymers and Ethanol ================================ Catalytic Cracking Oil refineries need to balance their outputs of various products (petrol‚ diesel‚ fuel oil‚ etc.) to match the demands of the marketplace. Catalytic cracking is the process in which high molecular weight (high boiling point) fractions from crude oil are broken into lower molecular weight (lower boiling point) substances in order to increase
