ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

CHEM 2123 and 2125 – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings

Lab #5-Enzymes NAME DATE LAB PERIOD Introduction Enzymes are proteins‚ though highly complex and diverse‚ they serve one basic function; to work as an organic catalyst. A catalyst‚ as defined by Merriam-Webster dictionary‚ is a substance that enables a chemical reaction to proceed at a usually faster rate ("Catalyst-Definition and more."). They function by reducing the activation energy‚ or energy required to start a reaction. The way enzymatic reaction works cannot be altered‚ but the

“Military Bearing” and how it affects the Army as a whole Bearing‚ put simply‚ is the appearance and demeanor of a person throughout the activities and circumstances that an individual is seen or observed. An individual is largely judged by others through the bearing that the individual exudes as he goes about his daily affairs‚ and thus it is very important that the person shows a bearing of competence and professionalism at all times. Militaries since the beginning of recorded history have set

*Compound Interest/Discount* Compound Interest When you borrow money from a bank‚ you pay interest. Interest is really a fee charged for borrowing the money‚ it is a percentage charged on the principle amount for a period of a year - usually. If you want to know how much interest you will earn on your investment or if you want to know how much you will pay above the cost of the principal amount on a loan or mortgage‚ you will need to understand how compound interest works. * Compound interest

conversion of light energy to chemical energy in the form of sugar and other organic molecules.” (Russell‚ Wolfe‚ Hertz‚ & Starr‚ 2010). Photosynthesis can be categorized into two main processes: light-dependant reactions and light-independent reactions. For the purpose of this lab‚ light-dependant reactions will be investigated. The reactants involved in photosynthesis include carbon dioxide‚ water and sunlight to produce glucose‚ oxygen‚ and water. The light reactions involve the capture and use of light

Experiment No. 1: MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting

9 Practical Applications of Journal Bearings 9.1 INTRODUCTION A hydrodynamic journal bearing operates effectively when it has a full fluid film without any contact between the asperities of the journal and bearing surfaces. However‚ under certain operating conditions‚ this bearing has limitations‚ and unique designs are used to extend its application beyond these limits. The first limitation of hydrodynamic bearings is that a certain minimum speed is required to generate a full fluid film of
