FE 106 GENERAL CHEMISTRY EXPERIMENT-1 DENSITY OF LIQUIDS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will learn how can we find the density of liquids and liquids of density how change effect of temperature‚ pressure‚ mass‚ volume and concentration. For this reason we will take NaCI solutions with different concentrations and we will measure their densities‚ so we will find out the effects of concentration on density of solutions. THEORY:

Lab #5 Questions and Answers 1. Which tool is better at performing protocol captures and which tool is better at performing protocol analysis? Wireshark is better for performing protocol analysis and Netwitness Investigator is best at performing protocol captures. Wireshark does well at both aspects‚ which makes it a little better. 2. What is promiscuous mode and how does this allow tcpdump‚ Wireshark‚ and NetWitness Investigator to perform protocol capture off a live network? Promiscuous

LAB 02: Measuring and Dispensing Liquids Introduction Pipetting is one of the most important and basic skills when it comes to experimental science. Good pipetting skills allow an individual to put trust in his or her results‚ prevent waste of materials‚ and assure reproducibility of results. In order to correctly pipette liquids‚ the volume range must be first determined. p1000 micropipettes have a volume range of 200 - 1000 uL‚ p200 micropipettes have a volume range of 20 - 200 uL‚ and p20 micropipettes

Chemistry 207 (Lab # 1) 9/11/12 Experiment #1: Cooperative Identification of an Organic Solid A. What needs to be done: In this lab‚ one will identify the identity of a colorless organic solid by experimentally finding the physical properties of the solid. Such properties include melting point‚ mixed melting point‚ and IR spectrum. With these properties‚ one will be able to compare their results of the organic solid to see if any other classmates have the same unknown sample. B. Timeline:

Experiment 3 Liquid-Liquid Extraction Discussion The success of extracting each compound out of the solution can be seen in the IR graphs for each substance. For ethyl 4-aminobenzoate‚ the N-H‚ C=O and C-O are distinguishable in their proper wavenumber positions. The amino N-H stretch was found between 3224 cm-1 and 3423 cm-1. The C=O was found at 1681 cm-1 and the C-O was at 1280 cm-1. The IR for benzoic acid also displays its significant bonds‚ O-H and C=O. The O-H was between 2566 and

The Cheating Culture 5 Key Points In the 1990’s‚ the Sears Auto Repair chain instituted a production quota for it’s auto repair staff‚ so the mechanics started billing their customers for maintenance on their cars for unnecessary and costly maintenance. Out of fear for losing their jobs‚ the act of giving repairs and charging the customers‚ respectively‚ for repairs their car did not need is relevant to the many stories in the cheating culture. One person was benefited for work they did not necessarily
