Mona Vaidya 02/04/2014 CHE 317 Laboratory Experiment #1: Simple Distillation of Two Volatile Liquids Containing Non-Volatile Impurities Introduction: Simple distillation is a commonly used method to separate and purify the mixtures of organic liquids into their original components. Mixtures of two miscible liquids with two different boiling points were separated. Therefore‚ it can be said that the two organic compounds are separated by exploiting the different boiling temperatures of the liquids

individual components. Familiar examples include the distillation of crude fermentation broths into alcoholic spirits such as gin and vodka‚ and the fractionation of crude oil into useful products such as gasoline and heating oil. In the organic lab‚ distillation is used for purifying solvents and liquid reaction products. To understand distillation‚ first consider what happens upon heating a liquid. At any temperature‚ some molecules of a liquid possess enough kinetic energy to escape into

Simple Sentences 1. At the five year old’s’ first‚ chaotic soccer practice‚ the unnamed team’s confluence of kooky ideas led to the team name of “Shining Star Frogs”. Metacognition: For this sentence‚ the use of a prepositional phrase establishes context for the sentence in that it shows why the team is gathered. With the addition of the adjective “unnamed”‚ the need for collecting team name ideas is further exemplified. The greek affix con allows for better understanding of the word because con

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Heat & Mass Lab 1: | | | 2/10/2011 2/10/2011 Executive Summary This experiment was conducted using a heat transfer unit. Many relationships were obtained and calculated from the observed results. To name a few; the log mean temperature difference‚ heat transfer coefficient‚ Reynolds‚ Nusselt and Graetz numbers. The main focus of this experiment is the heating and cooling of the oil fluid. This was achieved using the heating component in the heat exchanger and water flowing
