Download Chem 2040G: Review Sheet for Chapters 14 and 19 - Spring 2004 Exam Preparation and more Exams Analytical Chemistry in PDF only on Docsity! Chem 2040G – Review for Chapters 14 and 19, Spring 2004 The final exam will be cumulative and is worth 150 points. You should study the review sheets for Exams I - IV and this sheet on Chapters 14 and 19. The final will draw heavily on previous exams and homework assignments, so if you understand how to do them then you should be in fairly good shape for the final (seehttp://www.ux1.eiu.edu/~cfrp/2040S04.htm for solutions). Be sure to study handouts from class and in-class assignments, too. You will be provided with a periodic table during the exam and you should bring a calculator with you. The exam will be two hours long, and the format will be similar to the midterm exams. There will be about 40 – 50 multiple choice questions, 20 matching, and 10 short answer questions, including at least one bonus. Most handouts, in-class assignments and review sheets are available at the web site listed above. The exam is on Wednesday, May 5, 2004 at 10:15 am in room 4180. Know who Francis Bacon, Count Rumford (Benjamin Thompson) and James Prescott Joule were and their contributions to proving the caloric theory of heat to be incorrect. Know that heat is a form of energy and that work of any kind can be converted to heat. Know that two units of energy (to measure heat or work) are Joules and calories and that nutritional information is measured in kilocalories (=1000 cal) which are often written as Calories with a capital “C”. Know the First Law of Thermodynamics (conservation of energy). Know the terms exothermic and endothermic. Know what type of tissue stores energy in the body. Know how the amount of energy released in combustion of alkanes relates to the number of carbon atoms in the chain. Know what a triglyceride is, recognize its structure, and identify the ester functional group in it. Know the structural differences between fats and oils and how these differences affect whether the substance is liquid or solid. Know how these structural differences relate to cholesterol production in the body. Know what catalytic hydrogenation is and know the terms saturated, monounsaturated and polyunsaturated. Know how catalytic hydrogenation is used to change the properties of fats and oils and how this affects their healthfulness. Know that cholesterol is a sterol (steroidal alcohol) and why it can be unhealthy. Know what drying oils are and know how reaction with oxygen affects triglycerides. Know what methods are used to prevent oxidation of the unsaturated triglycerides that we consume. Know what geometric isomers are. Understand the terms cis- and trans-. Know how cis- and trans- structures affect the properties of triglycerides. Know the terms polymer and monomer. Know a general definition of plastic. Understand the differences between straight, branched, and crosslinked polymers. Understand the difference between a copolymer and a homopolymer. Know that the two main reactions for forming polymers are addition and condensation, and be able to predict the products that will form from each type of reaction if you are given the monomers that are reacting. Know what type of polymers polyethylene, nylon, protein, and “slime” are.
