The Weight of The Things They Carried Tim O’Brien makes a very big deal out of the concept of “truth” throughout his novel The Things They Carried; such a big deal‚ in fact‚ that over the course of his work he continually redefines and even contradicts himself as to what “truth” really is. In the chapter entitled “How to Tell A True War Story”‚ O’Brien offers a multitude of criteria that supposedly defines what does and does not make a true war story. O’Brien offers the first commandment for

Analysis of a Chloride Salt CHEM 1001 Purpose: To illustrate typical techniques used in gravimetric analysis by determining quantitatively the chloride content in an unknown soluble salt. Theory: AgCl(s) is a very insoluble solid‚ yet still does have some solubility. Because of these traits‚ the following reaction is able to occur: Ag+(aq) + Cl−(aq) → AgCl(s) . This reaction is able to occur in both directions. When a soluble silver salt such as AgNO3 is added to a solution containing Cl−(aq)

Determination of Molecular Weight of a Volatile Liquid By Vaporization: Dumas Method Background of the Study Problem In this experiment‚ an unknown liquid is in need to be identified and one of the key factors to identify it is to determine its molecular weight. In order to determine the molecular weight of a particular substance which in this experiment’s case is a volatile liquid‚ the need to convert the liquid into a gas arises. The relation among the pressure‚ volume‚ temperature and the number

Titration is a method used to help determine the concentration of an unknown solution (the analyte) by using a solution of known concentration (the titrant).1 In medicine‚ titration helps doctors determine unknown concentrations of substances in the blood or urine‚ and it is useful in determining the proper dosage of medication. Titration can determine fat and water contents‚ and unknown concentrations of vitamins. With food‚ titration can be used to determine whether cheese or wine is adequately

questions about the system of three unknown red solutions. Based on the experiments conducted and the data collected‚ I am able to conclude information about the three red solutions that will lead to a possible identity of each red solution. Starting with red solution #1‚ we are able to conclude that there are no nanoparticles in this solution and that is a molecular compound due to the fact that when potassium iodide was added‚ there was no color change and no precipitate formation to indicate that a chemical
