Jacob Hernandez October 23‚ 2014 Hima Lahari Marneni CHEM 1411. 114 Post Lab Report 6 Introduction The purpose of this lab is to determine the concentration of HCl when titrated with a standardized NaOH solution‚ through means of the titration method. My hypothesis is When an unknown concentration of HCl is titrated with a known volume of standardized NaOH solution‚ one can gather enough data to determine the concentration of the unknown (HCl). My prediction is If an unknown concentration of HCl

Lab 6 1. Why is it important to prioritize your IT infrastructure risks‚ threats‚ and vulnerabilities? It is important to prioritize because you must be aware of what the risks‚ threats‚ and vulnerabilities there are to your infrastructure. You need this so that you know where the most attention needs to be focused on. 2. Based on your executive summary produced in Lab #4 Perform a Qualitative Risk Assessment for an IT infrastructure‚ what was the primary focus of your message to executive

PHYS 111N Experiment 06: Friction Submitted by: Porsha Renee Sumner Lab Partners: Amber Carter‚ Emily Rawles‚ Clayton Scott Wednesday‚ March 6‚ 2013‚ 9:00 AM Lab Instructor: Uttar Pudasaini Introduction In this experiment we will be examining how the kinetic friction coefficient is altered by changing the mass‚ surface area‚ speed‚ and material contacting each other. In order to find this value‚ we will be using a pulley apparatus that will allow us to measure the average velocity and manipulate

Determination of the Resonance Stabilization Energy of Benzene Using Bomb Calorimetry Kaitlynn‚ Jesse ‚ Belinda Truman State University Abstract The resonance stabilization energy of benzene is investigated by the combustion of cyclododecatriene. The heat of combustion for cyclododecatriene was determined using bomb calorimetry and used to solve for the stabilization energy of benzene. The bond stabilization energy of benzene is found to be 167.6 ± 388

University of Nebraska at Omaha Bomb Calorimetry Physical Chemistry 3354 Enthalpy of Combustion: 1‚2-diphenylethane January 6‚ 2014 Author: Jon D. Paul Signature Professor: Dr. Edmund Tisko Date Abstract Experimentation involving constant volume calorimetry produces the heat of reaction for many substances. When choosing adiabatic conditions we are allowed to focus on the reaction system while neglecting everything else. The reactions that are studied should proceed relatively
