Kayla Adkins Forensic Chemistry Exam 2 I have been honest and observed no dishonesty. 1. In specific detail‚ describe a published procedure for the definitive identification of Heroin utilizing gas chromatography-mass spectroscopy (GCMS). Heroin is a white crystalline powder with no odor and a bitter taste. It is a derivative of morphine in that the –OH (hydroxyl group) is replaced by an acetyl group‚ -OCOCH3 and has a molecular formula is C21H23NO5 with a molecular weight of 369.42

Group Member: Victoria Coe Due Date: May 2‚ 2011 Teacher: Louth‚ Ellen Mary Class: Chemistry 11 Ad Introduction: An empirical formula of a chemical compound is the ratio of atoms in simplest wholenumber terms of each present element in the compound. For example‚ Glucose is C H O ; it’s empirical formula is CH O. 6 12 6 2 A hydrate is a compound that is chemically combined with water molecules. In contrast‚ an anhydrate does not contain water‚ and has had all of its water removed. Purpose:

BACKGROUND/INTRODUCTION Organic chemistry is the branch of chemistry that deals with carbon containing molecules. Carbon can bond to other atoms forming multiple chains and rings‚ thus creating an unlimited number of organic compounds to exist. Each organic compound has many chemical and physical properties associated with its structure. In this experiment‚ both the boiling point and the melting point were used in order to identify different organic molecules. The boiling point of a liquid is

models of elements‚ compounds‚ and mixtures. The lab asks you to examine conceptual models of matter in which atoms of one element are represented by nuts while atoms of another element are represented by bolts. After examining each model‚ complete the following tasks: a. sketch a representative molecular picture of the model; b. describe the composition of the model in words (does the model contain atoms‚ molecules‚ or both?; does the model represent elements‚ compounds‚ or both?; does the

9405 = 24% In this example‚ the lender stated a simple interest rate of 10 percent. Yet you actually are paying an effective APR of 24 percent once you add in the fees and you do not have the use of the full loan for the entire loan period. 3. Compound interest arises when interest is added to the principal so that from that moment on‚ the interest that has been added also itself earns interest. This addition of interest to the principal is called compounding. The following formula gives you

Integrated Case 5-42 First National Bank Time Value of Money Analysis You have applied for a job with a local bank. As part of its evaluation process‚ you must take an examination on time value of money analysis covering the following questions. A. Draw time lines for (1) a $100 lump sum cash flow at the end of Year 2‚ (2) an ordinary annuity of $100 per year for 3 years‚ and (3) an uneven cash flow stream of -$50‚ $100‚ $75‚ and $50 at the end of Years 0 through 3.

Background Information: There are many ionic compounds that contain one or more waters of hydration in their formulae. They exists either in anhydrous or hydrated form. Most anhydrous compounds have a strong tendency to absorb water from the humidity in the atmosphere and shifts into a hydrated form. Because of that phenomenon‚ those compounds are used to reduce moisture in places where water moisture can damage certain products. The anhydrous compounds are separated into three categories: hygroscopic

such away that its component cannot be change by simple distillation. Objective In this experiment we aim to demonstrate that we can separate two volatile compounds from a mixture due to the different chemical properties of each compound. We will accomplish this by a separation procedure known as distillation‚ which relies on each compound having a distinct and separate boiling point. Our pure products will be analyzed with gas chromatography to determine the success of the distillation. Data

Recrystallization is used for the purification of solid compounds. The recrystallization process relies on the fact that majority of compounds are more soluble in hot solvent than in cold. The hot saturated solution containing the compound will have unwanted impurities and will be filtered out and cooled to produce the pure crystal constituents of the compound. Thin layer chromatography can be used as a physical method to segregate compounds from natural sources. E.g. Spinach leaves are visibly
