Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

1. Discuss the circumstances in which an auditor would prepare a proof of cash. (6 marks) Auditors would prepare a proof of cash when the client has material internal control weakness in cash. If all cash receipts were deposited and all deposits were recorded in the accounting records‚ all recorded cash disbursements were paid by the bank and all amounts that were paid by the bank were recorded. 2.

As a side note‚ upon researching the molecular weight of sugar‚ I found it to be 342.30 g‚ not 331.23 g‚ however‚ in my calculation I used 15.00 g as the molecular weight of O2‚ whereas online 16.00 g was used. Eight8 g of sugar were placed on the scale‚ and then transferred into the volumetric flask (Table 8 shows the calculations of the molecular weight‚ moles‚ mass‚ volume and molarity recorded before doing so). Distilled water was added to the sugar until a total of 25mL were in the flask. Then

EXPERIMENT 4B: THE MENDELEEV LAB OF 1869 Materials: 30 element cards‚ periodic table Aim: How can we identify elements based on their propeties? Background: Russian chemist Dmitri Mendeleev is generally credited as being the first chemist to observe patterns emerge when the elements are arranged according to their properties. Mendeleev’s arrangement of the elements was unique because he left blank spaces for elements that he claimed were undiscovered as of 1869. Mendeleev was so confident

the same properties as concrete. So the standard sand was chosen and the following properties were determined to it: 1. Consist of pure siliceous material. 2. The particles are nearly spherical shaped. 3. The size of its particles is smaller than 0.85mm (Pass through 15 B.S. sieve) and bigger than 0.60mm (Retain at 25 B.S. sieve).

The Virtual Lab – ELISA Test Lab: Immunology 09/04/2013 Instructors: Dr. Charlie Wilson Written by: Dipen Patel I. Objective: The purpose of the lab was to learn the procedure of performing an ELISA test to determine whether a particular antibody is present in a patient’s blood sample. ELISA is an abbreviation for “Enzyme-linked Immunosorbent Assay." II. Introduction: The interaction of antigen and antibody outside the body can be used to determine if patient
