Ocean County College Department of Chemistry Identification of Metallic Ions Purpose: The purpose of this lab exercise was to perform and observe the flame tests of some alkali and alkaline earth metal ions. When electrons in metallic ions are grounded‚ their configuration is stable. In other words‚ the loosely bound electrons in the valence shell of the atom are satisfied at their “low” energy state. They do not require to be balanced by emitting any type of radiation or receiving any

In the unknown identification labs‚ we have identified our unknown as Pseudomonas aeruginosa. Pseudomonas aeruginosa is Gram negative and rod shaped that we found to be motile in the lab. Our strain of P. aeruginosa formed colonies that were round in shape and had scalloped margins on nutrient agar. On our agar slant‚ the P. aeruginosa colonies had a filiform appearance on the edges. I think we correctly identified our unknown as P. aeruginosa because we performed several different tests‚ eleven

Risk Identification Nathaniel Seigler CPMGT/302 July 13th‚ 2015 Petula Brown Risk Identification Risk identification is an important step towards successful accomplishment for any project and any organization. This week’s efforts covered classroom conversation on risk identification and required that I complete a Worksheet developed by the University of Phoenix. That worksheet included three different scenarios‚ one of which I have chosen to write this brief response on. My goal is to describe

The 2013 law requiring Texans to show a valid identification card before voting in any election has caused quite a controversy since its implementation even though the national Constitution clearly specifies any state is allowed to require what it deems necessary to ensure lawful elections. The main incentive for implementing the requirement was “… a fear of voter fraud (especially‚ a suspicion that non-citizens who are illegally in this country are voting) (Denniston‚ 2014). While this law while

Are Eyewitness Identifications Reliable Guneet Singh Roll no: 5826632 HAY 120 Introduction to Forensic Psychology Are Eyewitnesses identifications Reliable? Eyewitness testimony is the description an onlooker gives in court‚ unfolding what they saw had happened at a specific occasion which is been investigated. It mainly includes identification of perpetrators or the details of the crime scene. Mainly recollection of events is detailed‚ but not always. This recollection is the proof

Problem Formulation and Identification MGT/350 December 13‚ 2010 Problem Formulation and Identification Complications are part of the decision-making process and vary from organization to organization. Our team intends to investigate and observe the decision-making process that is most prevalent in their organization. We will do this by comparing and contrasting the problem identification and formulation styles in the organizations. Last we will discuss

Unable to read the Gram Stain at first it was later confirmed that Unknown #7 was a gram negative bacteria. When introduced to Starch Unknown #7 produced no zone of clearing showing that it did not contain the enzyme amylase. When introduced to the Lipid Unknown #7 did produce a zone of clearing indicating that it did contain the enzyme lipase. When introduced to Casein Unknown #7 produced no zone of clearing indicating that it did not contain the enzyme protease. When streaked onto the Gelatin‚

IDENTIFICATION OF AMINO ACIDS BY MEANS OF TITRATION CURVE ABSTRACT The aim of the experiment was to identify an unknown amino acid through acid-base titrations which was prepared in water to form an acidic solution. Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion

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
