Pearson Lab Scavenger Hunt In Week Three through Week Eight, you conduct scientific experiments in an online lab environment. The content of the labs vary with each week but the structure remains the same. This week, review your Week Three lab instructions and assignment to become acquainted with the essential elements of each lab. You are not required to complete the actual lab this week, but rather to locate various pieces of information about the labs to help prepare for completion of the labs in

Enter the data for the sample you used in each trial (5000 rpm, 10000 rpm, etc) in the appropriate columns and the corresponding g-force, number of layers, and position of layers position results. You will need to use the following formula to assist with your laboratory report G-force 0 00001118 x radius of centrifuge arm x (rpm)2 The radius
cloves by steam distillation. You will then separate a component (acetyleugenol) from the oil by liquid-liquid extraction. Finally, you will isolate the acetyleugenol by using a rotovap for reduced pressure distillation, which will remove the organic solvent (dichloromethane). Background Whole cloves contain between 14% and 20% by weight of essential oils, but only half of that can be isolated as acetyleugenol. Clove oil contains two basic compounds: eugenol and acetyleugenol.
Experiment 3: Oxidation of Borneol to Camphor By: Evan Holley Lab partner: Jeffrey Horton T.A.: Garret CHM2211L-008 07/12/2015 Introduction The overall goal in this lab was to oxidize borneol, a secondary alcohol, into camphor, which is a ketone. For the purposes of oxidation chromic acid was utilized, which was prepared by adding a 1:1 ratio of chromium trioxide to dilute sulfuric acid. The oxidation reaction occurs as a two-step reaction. The first step involves the formation
series of major upgrades and extensions (1). Valero is an independent refiner that purchases a variety of oils such as crude oil and sour and residual oil (2). The complex refining and distillation processes for Valero can be compared to the experiments performed in an Organic chemistry lab. From what the company’s procedures are to what the Lab procedures are, a similarity can be seen just on a larger scale. Figure 1 outlines the size of the Valero refinery.

RADICAL HALOGENATION AND GAS CHROMATOGRAPHY Abstract In radical halogenations lab 1-chlorobutane and 5% sodium hypochlorite solution was mixed in a vial and put through tests to give a product that can then be analyzed using gas chromatography. This experiment was performed to show how a radical hydrogenation reaction works with alkanes. Four isomers were attained and then relative reactivity rate was calculated. 1,1-dichlorobutane had 2.5% per Hydrogen; 1,2-dichlorobutane had 10%; 1,3-dichlorobutane
Isolation and Identification of Essential Oils Lab Report Name: Lauryn Tonou Partner’s name: Tiffany Keener Date submitted: 11/02/2015 Introduction Essential oils are the concentrated extracts of volatile, non-water-soluble aroma compounds from plants. They are widely used in cleaning products, cosmetic products, and perfumes, also as flavorings in foods. Essential oils are actually mixtures of organic compounds sample. However, the purpose of the lab will be to isolate and identify essential
Synthesis of Acetaminophen Lab Report Bijal Patel, 20467049 Partner: Poojan Parikh T.A.’s: Long Pu CHEM 123L, Section: 006, Rm: ESC 149 Tuesday February 4, 2013, 2:30pm-5:20pm Experiment Done: Tuesday January 22, 2013 Introduction Acetaminophen was first introduced in 1955 (Richman, 2004). It is an over-the-counter drug that relieves pain and reduced fevers. Acetaminophen is considered an alternate to aspirin since it does not irritate the stomach (Richman, 2004). It also has very
