Energy Flow Systems Richard White’s Organic Machine‚ and William Cronon’s Changes in the Land‚ both examine environments as energy flow systems. The energy flow model was utilized by the authors to explain relationships within ecosystems. Richard White’s thesis is to examine the river as an organic machine‚ as an energy system that‚ although modified by human intervention‚ maintains it’s natural‚ its "unmade" qualities. White emphasizes on energy because it is a useful concept that can be easily

Experiment Four: Organic Synthesis of Aspirin Abstract The purpose of this experiment is to synthesize a common organic product called acetylsalicylic acid (aspirin)‚ and to become familiar with the optimum conditions needed for successful yields. Aspirin is produced from an acid catalyzed reaction between salicylic acid with acetic anhydride. The crystalline aspirin is synthesized and purified by recrystallization‚ although there is not a hundred percent yield due to sources of error. Introduction

NaOH Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance

1. List all Functional Groups 2. What is an alkane? List its properties. 3. Write the name and formula of simple alkanes 4. Consider this compound (CH3)2CHCH2C(CH3)3. Name this. a. redraw it clearing all brackets and parentheses. b. Find the longest chain. Check from all directions. If it is not horizontal‚ rewrite the compound that so that longest chain IS horizontal. c. Number the carbons of the longest chain backwards and forwards.

Have you ever wondered if organic products is really worth paying more than regular products? Have you ever wondered if organic products are actually healthier for you? People who buy organic foods and products are usually seeking assurance that the food or products they are buying is gentle to the earth and that the food they are buying and eating is safe. Many studies have found that organic produce is more nutritious than non-organic produce. The term organic simply means using no chemicals

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
