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
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. As a result of Dalton’s Law and Raoult’s Law, both of these substances can be removed from the cloves with a steam
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
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 of
Qualitative Analysis Lab Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds, one solid and one liquid, from an ethereal solution using the techniques of chemically active extraction, vacuum filtration, simple distillation, and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges, and analyzing IR and proton/carbon NMR spectrums It was determined
Theory: The goal of the lab was to separate a neutral compound and an acid from an unknown mixture. The DCM (Dichloromethane) was added to create the organic layer. Both the neutral compound and acid were insoluble in water so aqueous NaOH was added. The acid would be deprotonated into an ion, which is soluble in water. Using the separatory funnel, the organic layer was separated from the aqueous layer. HCl was added so that the ion would protonate back into the acid and precipitate out of solution
Preparing Esters by esterification method using carboxylic acid to an alcohol, which is 1.0 ml of ethanoic acid to the ethanol, and ethanoic acid to the propan-1-ol, also adding H2SO4 as a catalyst for the reaction Abstract: Esters are a group of organic compound, famous for their interesting odours and smells. In this investigation student used ethanoic acid and ethanol with sulfuric acid as catalyst to produce ester, which was known of its smell. However it was expected to have a pleasant smell
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
