Determine the concentration of an unknown copper (II) sulfate solution by using colorimeter Introduction: The concentration of the solution also alterations the proximity of the solution. For example‚ the more focused concentration will frame to be denser than more weakened concentration of copper (ii) sulfate. This implies there is a connection between the concentration of an solution and its absorbance. Along these lines‚ this test is set up to discover the kind of connection between the concentration

Unknown Anomaly In the not so distant future‚ humanity has expanded its reach to distant planets‚ seeking refuge from Earth’s depleted resources. Among these colonies is Terra Nova‚ a swarming settlement on the outskirts of known space. Captain Brian Laurier leads the exploration vessel‚ the Mercury X‚ on a mission to scout new planetary systems for colonization. During a routine mission‚ the Mercury X encounters a peculiar anomaly—a rift in space-time that defies all known laws of physics. Its

Introduction The purpose of this lab was to explore the properties of an unknown compound. An unknown was given and a cation flame test and anion test was performed to determine the identity of the compound. Once the identity was determined‚ the properties were explored. Experimental To determine the cation of the compound‚ a cation flame test was performed. A bunsen burner was lit until a medium blue flame was burning. The given unknown was scooped onto a nichrome wire loop. The wire was held in the flame

Alyse Rose Microbiology Lab Bacterial Unknown March 25‚ 2013 Bacterial Unknown Report Each student was given an unknown bacteria to figure out. I was given the unknown bacteria S38. Everybody is supposed to do all sorts of test to identify the bacteria. The first thing I did was smear my bacteria on a liquid medium. I then proceeded to incubate the medium for 24-48 hours. 1. GRAM STAIN The next step I took in finding my unknown bacteria was to gram stain it. This is used to differentiate

-1Determination of an Unknown Liquid (2-butanol) Through Fundamental Analysis Lee Billips Department of Chemistry‚ Shippensburg University‚ 1871 Old Main Drive. Shippensburg‚ PA‚ 17257. Abstract: The identification and characterization of unknowns are an important part of organic chemistry. It is fundamental to know experimental methods to deductively identify compounds (1) . The determination of unknown #6 (2-butanol) was identified by a series of test; first taking the boiling point (94-96

20th century. Educated at Oxford‚ he attracted attention as a prominent member of a group of young leftist writers who generally expressed a socialist viewpoint. The poem I have chosen for this essay is "The Unknown Citizen". I felt the time period reflected W.H.

Chemical T ests for Unknowns Chemical tests have been developed as a means of identifying what functional groups are present in an unknown compound. Since IR and NMR spectroscopy has been developed‚ they are no longer critical to unknown analysis‚ but they can still be useful for confirming what you have determined by spectroscopy. Some of them look cool too! In order for a chemical reaction to work as a chemical test‚ it must 1) create a visible result (a color change‚ a precipitate‚ etc)

Fear of the Unknown Lord of the Flies By: Sam Baldwin 2012-05-22 Ms. Reis ENG30S Fear is one of the most powerful emotions that control the way any human being acts in certain circumstances. A distressing emotion aroused by impending evil and pain‚ whether the threat is real or imagined is described as fear. One of many prominent themes in William Golding ’s novel‚ the Lord of the Flies‚ is Fear of the unknown. From the beginning of the novel‚ the boys fear what they cannot see‚ the parts

The identification of an unknown bacterial environmental isolate through a series of morphological‚ physiological and differential exercises. The purpose of the environmental isolate report is to learn what is necessary in order to take an unknown environmental isolate (EI) and identify it. This was achieved through a series of exercises that provided information on the morphological‚ physiological and biochemical traits of the EI which were then compiled and interpreted in order to make a presumptive
