The knowledge of chemical analysis today has become important not only for scientists in their research but in fact bears influence in our daily routine as well. To recognize and classify these uses‚ we have to first understand‚ what is chemical analysis?Chemical AnalysisChemical Analysis is a body of procedures and techniques used to identify and quantify the chemical composition of a sample of substance.1 It may be said as a collection of all the techniques required to obtain any chemical information

PAPER and COLUMN CHROMATOGRAPHY REPORT 1. 2. The unknown code is an amino acid‚ Glycine. To justify the reason is because the retention factor is the same exact number as the Glycine. The data of the unknown shows everything to be exact with the data of the Glycine 3. The mobile phase is the more polar during the capillary action of the experiment. As soon as the paper touches the mobile phase‚ the solvent rises to the amino acids. This is where you can find polarity of the amino acids.

Unit 3 Assignment 1 – Choosing Port Scanning Software 1. The act of systematically scanning a computer’s ports. Since a port is a place where information goes into and out of a computer‚ port scanning identifies open doors to a computer. Port scanning has legitimate uses in managing networks‚ but port scanning also can be malicious in nature if someone is looking for a weakened access point to break into your computer.(1) 2. To determine services that a computer is running and shut down services

Dr.Tawfeq al.Qaimare Rifqa Shawer Lab report 5 21-3-2013 Adsorption Chromatography Introduction: The technique of adsorption chromatography may be illustrated by a description of how two dyes are separated when a solution of the dyes is passed through a column of powdered silica contained in a vertical glass tube‚ it’s a method used to separate solids or liquids. At the first the two dyes are adsorbed at the top of the column‚ giving this region a nearly dark blue color. However‚ when
