Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

Extraction of DNA Molecule of an Onion In an Aqueous Solution By: Introduction DNA(deoxyribonucleic acid) is found in every living organism. It provides the information and instructions to build and regulate cells in organisms. The information it contains is used when organisms are being reproduced. It is made up of two polynucleotide chains known as DNA strands. Within the two chains there are four nucleotide units: adenine‚ thymine‚ cytosine‚ and guanine. Materials and Methods An onion

Introduction DNA (Deoxyribose Nucleic Acid) is a nucleic acid that has many names‚ each representing the phases that it undergoes (chromosomes‚ chromatin‚ genes/alleles); it resides in the nucleus (bound by 2 *phospholipid bilayers) of almost every cell in the body (red blood cells being an exception). DNA (your genotype) is double stranded and is responsible for replicating (from 46 to 92) during Interphase‚ so that mitosis can make new cells‚ repairing and allowing for growth in the body. It is

Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental level

EXTRACTION OF TRIMYRISTIN FROM NUTMEG: Paul I. PURPOSE: The purpose of this experiment was to illustrate the extraction of a solid natural product from its natural source by partition with the aid of an organic solvent. Extraction is the process by which a compound or mixtures of‚ is transferred by separation from one phase into another. In this case‚ the major triglyceride contains a single fatty acid identified as myristic acid. It is a substituent

Date Submitted: Sept. 2‚ 2014 EXPERIMENT NO. 1 EXTRACTION AND ISOLATION OF PROTEINS Background of the experiment Pure proteins are not readily available for study or use. There are certain methods that should be done in order to obtain proteins from its sources. The objective of this experiment is to isolate casein from milk and albumin from egg and to identify and explain the principles behind the methods employed for protein extraction. Results and Discussion There are many possible sources

SOP: Solid phase extraction of cylindrospermopsin in filtered water samples Document identifier: SOP_TOXIC_UDU_05F Prepared by: James S. Metcalf and Geoffrey A. Codd‚ UDU Date: 7 July 2005 1 Introduction In order to determine the concentration of cylindrospermopsin in the extracellular fraction of filtered environmental waters‚ solid phase extraction (SPE) is necessary to concentrate the toxin to concentrations capable of being detected by HPLC. 2 Experimental 2.1 Materials

DNA Extraction of a Musa acuminata Biology Lab Report \Analyze and Interpret A number of steps are required to isolate DNA from cellular contents. Describe what happens at each step‚ and why it acts to separate the parts of the cell. /6 There are three specific steps required to isolate DNA from its cellular contents. The steps used to remove and expose DNA from its cell are: breaking down the food type you are using by crushing it‚ for example a banana or strawberries‚ exposing the substance

Kate Kirby June 6‚ 2013 Title: Extraction of an Unknown Compound Purpose: The purpose of this experiment was to separate a mixture of two or more unknown compounds and identify them based on their melting point and reactivity with an acid or a base. Compound studied/Reactions: The organic solvent used in this experiment was methyl t-butyl ether (MTBE‚ 2-methoxy-2-methylpropane). The unknown that dissolved in the MTBE‚ but was insoluble in water. MBTE is very volatile and flammable. It was
