Lab #4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles

The Benefits of Organic Food—Draft #1 Organic food‚ once only found in health food stores‚ is now a consistent element at local supermarkets. So what is the difference between a conventionally grown apple and an organic one? The answer is in the way the crop is grown and what it is and is not exposed to. In order to be labeled “organic” the farmer who grew it used renewable resources and conservation of soil and water methods. Also‚ organic farmers do not use conventional pesticides or weed killers

October 30 2012 Similarities and Discrepancies between GMOs and Organic Products encompass analyzation Why spend more money on organic food? Why are GMO products lasting longer? These are commonly asked questions which will be explained. By the definition of GMO products‚ they encompass alimentary products grown from seeds that have been genetically altered. Organic products are those that are grown under the traditional way‚ without any intervention of Bio-engineering‚ and also without the usage

13. ORGANIC CHEMISTRY IV) ALKYNES SYNOPSIS Alkynes are commonly known as acetylenes. Acetylene is the simplest and important member of the alkyne series. • Alkynes contain – C ≡ C – • General molecular formula of alkynes is CnH2n–2 • Triple bonded carbons are ‘sp’ hybridized and greater s – character is associated with it. • Alkynes will exhibit chain‚ position and functional isomerism. • Their functional isomers are alkadienes and cyclo alkenes. • The minimum number of carbons required to exhibit

Ellen Grant Honors Bio I Organic Compounds Problems and Objectives: The purpose of this lab was to select the suitable test for an organic molecule and define the safe process for that test. An organic molecule is normally found in or produced by living systems. (Unknown Author‚ 2014‚ www.biology-online.org/organic_molecule)In this lab one was supposed to infer the results of the test and be able to identify if major biomolecules are present. You were to analyze a variety of tests including

This experiment has been carried out to observe whether the hamster prefers organic or conventional foods better. Hammy was put into the place where there were two identical pieces of food‚ one organic‚ one conventional and it gets to choose either of them to eat. The reason hamster is used instead of the human is because it is unbiased‚ it judges the food from the smells unlike human that we have more complex thinking and tends to be considering about other things. Also‚ the human body is not good

Organic Chemistry Laboratory Report. Experiment 1: Crystallization. Objectives: 1. To study the crystallization process. 2. To identify the best suitable solvent to use for the crystallization process. 3. Gain an experience in purifying an organic compound by the techniques of the crystallization. Introduction. Crystallization is a technique which chemists use to purify solid compounds. It is one of the fundamental procedures each chemist

ESTERIFICATION SYNTHESIS OF PEAR OIL One of the major uses of Esterification (C(=O)-C-R) is forming compounds with different odors which can be used to make different synthetic and natural flavorings. Using the chemical and physical properties of organic compounds‚ an ester was catalyzed from the reaction of a carboxylic acid with an alcohol‚ producing an odor similar to that of pear oil. The mechanism of this Fischer- Esterification process is outlined as follows:

EXPERIMENT 3 DETERMINATION OF ORGANIC MATTER BY WALKEY- BLACK WET OXIDATION METHOD OBJECTIVE: This method determines the percentage of organic carbon and organic matter in the soil. INTRODUCTION The soil sample is suspended in standard potassium dichromate (K2Cr2O7) solution to which concentrated sulphuric acid is then added. The heat generated on adding the sulphuric acid and the presence of chromic acid creates strong oxidizing conditions. The excess chromic

growth in organic products. Ceres increased their revenues by over 75% in just five years‚ while growing profits by over 25% (based on Exhibits 2‚ 3 & 4). Ceres’s basic strategy started with its founder‚ Jonathan Wydown‚ to promote sustainable organic gardens and landscapes to environmentally conscious consumers. Mr. Wydown has been a proponent of soil preservation‚ biodiversity‚ and natural fertilizers and pest control. Mr. Wydown was confident that the same principles behind organic farming would
