in the War In the poem‚ “The Unknown Citizen‚” a short eulogy is presented at a funeral for an unidentified soldier. When providing details about the citizens life‚ the speaker instead uses impersonal facts and government based statistics‚ rather than intimate components about who the soldier was personally. The author also displays the tone of the poem as lighthearted‚ making the speaker seem untroubled about the death of the soldier. In W.H Auden’s poem‚ “The Unknown Citizen‚” the author uses his

Purpose: The purpose of this was to determine the concentration of sodium carbonate in an unknown sample by titration. The solution of hydrochloric acid was prepared and standardized using Na2CO3. Observations: Week 1: Standardizing hydrochloric acid using sodium carbonate with bromocresol green indicator Table 1: Titration of sodium carbonate using hydrochloric acid Trial | Mass of Na2CO3 (g) | Burette Reading (mL) | Final Volume of HCl (mL) | | | Initial | Final | | 1

Goals The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness

and Report: Introduction: The experiment was conducted to find the unknown molarity of HCL. The unknown molarity of HCL was found by the use of the titration method and then comparing the results between the titrant and analyte HCL solutions. Molarity is a concentration unit‚ it is defined by the number of moles the total volume of the solution. This experiment included a process called titration‚ used to work out the unknown concentration of a known substance. The process of titration is adding

The Tomb of the Unknown Soldier is a practice utilized throughout the world to memorialize soldiers who have died in modern wars without being identified. The first monument of this kind was the Tomb of Unknown Soldiers in Frederica‚ Denmark (1858)‚ which memorialized unknown soldiers who died in the First War of Schleswig. Another such Tomb of the Unknown Soldier is found in Philadelphia‚ Pennsylvania and was erected in 1866 to honor those soldiers who died during the American Civil War. The history

Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or

we have learned in the lab to identify two unknown organisms. PROCEDURE I was given unknown #76. I performed the streak plating method with my unknown organisms. To perform this exercise I needed a TSA plate and labeled the bottom of it with my name‚ group number and organism. I also divided the bottom into three sections. After that‚ I sterilized my inoculating loop using the bunsen burner flame. After letting the loop cool‚ I reached into my unknown test tube with my loop and grabbed the organisms
