My group had been given a specific task to investigate according to the lab manual1. We were employed by the Environmental Protection Agency as chemists. Our task is to identify an unknown compound that was found in a nearby landfill. In this laboratory, the unknown compound was given to us by our TA. The main goal of this experiment was to correctly identify the unknown compound. We also wanted to discover as many chemical and physical properties as possible. Physical properties are those that can be determined without performing any changes to the identity of the substance. Chemical properties are properties that can only be determined after a chemical reaction is performed in order to change the identity of the substance according to “Physical”2 …show more content…
This means that the unknown compound does conduct electricity. The compound was tested and had a pH of 5. This means that the compound is acidic according to the pH scale. Being acidic means that the substance has more hydrogen ions than hydroxide ions according to “pH”3 .The chemical and physical properties are stated in Table 1. The compound was soluble in water and hydrochloric acid, but was not soluble in sodium hydroxide, toluene, and acetone as indicated by Table 2. For a compound to be soluble it means that the compound must be able to dissolve in a certain liquid. This was proven by using the solubility tests. Since the unknown compound was soluble in water it means that it is a polar or ionic compound, and since it is soluble in hydrochloric acid it means that it is probably an organic base. It was soluble in water because water is a polar molecular and since it’s polar, the molecules interact using hydrogen bonds and dipole-dipole intermolecular forces. This then leads to the fact that the partial negative and positive parts of the water molecule can break the bonds of ionic and polar molecules which causes them to dissolve within the

    Jonathan Desmond DCN Lab 5 Kali Kali is a live Linux distribution which can be put onto a USB and loaded directly onto a computer. Kali, having being bundled with a variety of testing tools such as Wireshark and Metasploit Framework, is utilized to assess the security of a target machine. The creator of Kali, Mati Aharoni first thought of the idea during a consultation which banned the use of external hardware as well as the stipulation that client computers could only be used if the data remained untouched. He then thought to use a live Linux distribution to assess the client’s security flaws.…

    The purpose of this lab was to analyze and examine periodic trends of the first 36 elements that are on the periodic table. Trends that were analyzed and examined are the atomic radius (AR) and the first ionization energy (IE) of the 36 elements. The hypothesis for this lab was that the elements that are in the groups that had the highest atomic radius would be in the same groups as those who have the the highest first ionization energy and the groups who have the lowest atomic radius would be in the same groups as those elements who have the lowest first ionization energy. In order for the lab to be completed, a chart that was split into four sections was made to collect all the necessary data that is needed to make the graphs. After the data has been collected, a graph that contains both trends was made on a piece of graph paper.…

    Task-5 a) • Metals Metal structure is made up of crystals of metals which are made up of positive metal ions and these ions are surrounded by a sea of delocalized electrons. To separate these substances from this crystal lattice a lot of energy is needed. In between the positive and negative ions is present a strong electrostatic force of attraction. That is the reason why metals have strong melting and boiling points. In order to slide one layer of the metal ions over the other layer very less amount of energy is used.…

    On January 29th, we conducted lab 2 which involved learning the basic tools of Dartfish and how to publish Dartfish videos to our own mediabook. The first step in the lab involved going to dartfish.tv and looking at the “3302 Class Resources folder and downloading the video trim file. I then opened the Dartfish software and as a class we reviewed some of the various resources in the software like the different screen options such as split screen or mosaic mode and different tools such as analyzing angle and distance of the video. I learned how to transfer the downloaded video from the computer library to the tray. It’s important to note that you can delete videos from your tray and it will still be on the computer’s library.…

    Speed, availability, and reliability are vital for a successful network infrastructure in terms of productivity and user experience. When first configuring this lab, I had to make the decision of whether or not to use one server to run all of the services or if the load should be distributed amongst multiple machines. I decided to go with the later, having a separate server hosting the wiki, another providing monitor services, and yet another acting as the DHCP, DNS and AD controller. While the last three were not required in the scope of this lab, I wanted to set up my initial network in a scalable manner, and this was the best solution for future growth. Distributing the services across multiple machines helps to reduce the processing that each box is required to do in order to fulfill requests.…

    The first objective of Lab 4 is to use structure activity relationships to predict the properties of an acid and the potency of hallucinogenic compounds. The overall goal of the laboratory is to examine quantitative structure activity relationships (QSAR) in a system that is either chemical or biochemical. The lab is divided into two parts; predicting the acidity of an organic acid, and predicting the hallucinogenicity of derivatives of mescaline. The materials of this lab for both part 1 and part 2 are small training sets, which are groups of similar chemicals with known biological activity, a computer to graph the data that is recorded in the tables, the internet resource MiLogP to generate LogP data, and computational programs that will…

    2-Methylcyclohexanol

    This happened to be a clear oily substance on the bottom of the Erlenmeyer flask, which could easily go unnoticed. Another thing that is provided by the results is an IR spectrum, which when analyzed it revealed that the functional groups present in the final product, 2-methylcyclohexanol, was indeed produced. The way that is revealed is through the peaks that are present on the IR spectrum because each peak represents a different functional group based on the location of the peak and the strength of it. For 2-methylcyclohexanol, the main identifying functional group would be the OH, which would be represented by a broad peak at approximately 3300 cm-1, and this peak is present. Also the IR can indicate that the functional groups present in the starting material, 2-methylcyclohexanone, in no longer there in the final product.…

    Unknown Ionic Compounds Lab Report

    When calculating the quantitative solubility of the unknown compound in water, the amount of water that was measured in the hydrated cylinder and poured into the flask could have been greater than expected. This is more likely than less water being used because more solute was needed to saturate the solution than expected. Another error that could have occurred during this part of the experiment was that too much of the unknown compound was added accidently to the solution than could dissolve. Most of the error in this lab occurred during the quantitative analysis since all of the percent yields of the precipitate were over 100%. This miscalculation could have been caused by the beakers not being washed out thoroughly between each reaction or by the mass of KCl measured on the electronic scale being greater than exactly 0.5 grams.…
