Distillation Purpose: To conduct the distillation process‚ simple or fractional. Procedure: 1. Add 5ml of 20% ethanol: water mix to the distillation flask. 2. Add 23 stir bar 3. Make sure that the thermometer bulb is just below the Claisen Head‚ carefully. Be very gentle with the thermometers and take care not to break them. 4. Label 3 vials‚ 1‚2‚ and 3. 5. Place receiving vial 1 on ice to collect the distillate 6. Start the distillation by piling up hot sand around the distillation flask with

Post-Negotiation Reflection Report I was the buyer in the Texoil Negotiation. I was offered $750‚000 and immediately counter-offered $375‚000 to re-anchor the position. This is because the first offer can otherwise exert a lot of influence. The target prices were clearly far apart; this is where the preparation start proves value and moves the seller to approach his reservation price. Specifically‚ I prepared objective rationale for my arguments and listed all the factors that I believe could influence

Lab Report Marisa McKinney P. 2 Purpose: To investigate the periodic variation of density in Group 4A elements. Background: When the elements are arranged in order of increasing atomic number‚ they exhibit periodic recurrence of properties. Elements in the same group in the periodic table tend to have similar physical and chemical properties. These similarities are due‚ in large part‚ to similarities among the electron configurations of the elements in a group. You can find periodic

is also known as fluid statics (fluid at rest) within the fluid mechanics field of study. This condition explains that in a stable condition‚ the fluid is at rest. The use of fluid in doing work is known as hydraulics‚ and the science of fluid in motion is known as fluid dynamics. INTRODUCTION The natural nature of fluids are they cannot remain stationary under the application of shear stress. However‚ fluid can apply force normal to any surface contacting it. If the fluid is considered as

Mr. Mihordea Motion of Atoms and Molecules lab summary In this lab the standard heat of combustion of magnesium was calculated by using the calorimeter. Also‚ the point of combustion of magnesium was to see how much heat would be released from fireworks such as sparklers. The concept of this lab was to find the difference in temperature from the beginning to end of combustion of magnesium and calculate

Introduction In this lab the main focus was projectile motion. A projectile is an object flying through the air that is only under the force of gravity (neglecting air resistance). A projectile moves both horizontally and vertically‚ which creates a parabolic flight path. In vertical projectile motion there is a constant velocity since there are no forces in the horizontal direction (neglecting drag due to air resistance). Consequently‚ there is no acceleration in horizontal projectile motion. In vertical

6 November 2012 SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports. Three fields of study are composed within this memo that includes Electrical Engineering‚ Environmental Engineering‚ and Petroleum Engineering. “Electrical Filters‚” (Electrical)‚ written by Joe Schmoe‚ is a lab report made by a student at a university. The College Board produced an environmental lab report named‚ “Monitoring Air Quality‚”

University of Texas at Tyler Lab 3C: Purification of L-Lactate Dehydrogenase By Affinity Chromatography on Cibacron-Blue Sepharose David Alexander 10-15-2014 Dr. Black Chem 4135.001 Abstract: Like the previous experiments‚ the ultimate goal of this lab was to purify the enzyme sample. However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally

Goals The purpose of the lab experiment is to explore simple harmonic motion (SHM). We will accomplish this through the validation of harmonic calculations and ultimately creating a time piece (oscillator) Method In part A (Simple Pendulum) we will measure the effects of mass on the period of the pendulum. We will also calculate the period using small angular displacements and compare the results. We will also explore the effects on the period when the angular displacement is not “very small”
