Objective: The objective of this lab was to find and examine the viscosities of ideal and non-ideal solutions. The ideal being the toluene/p-xylene and the non-ideal being the methanol/water. The second objective of this lab was to investigate the temperature dependence of viscosity (Halpern‚ 17-1). Introduction: Viscosity is the resistance to flow of a certain fluid. In this experiment two solutions are used. According to the definition of viscosity mobile liquids have a relatively low viscosity

In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To

Procedure and Analysis: The lab began with the group making a rough estimate of the force required from each arm to lift the weight up to be about 700N per arm. We then drew a force diagram for the force acting on the barbell and when the lifter held the barbell over his head. Were: B= the angle=35 degrees Fn= The normal force m= mass g=gravity F= the force exerted by each arm We then used the following equation W = mg to calculate the weight of the barbell. Were: W= weight

IS3110 LAB 5 Identify Threats and Vulnerabilities in an IT Infrastructure 1. What are the differences between ZeNmap GUI (Nmap) and Nessus? NMAP is primarily a host detection and port discovery tool. Instead of using Nessus to look for specific vulnerabilities against a known quantity of hosts‚ NMAP discovers active IP hosts using a combination of probes. On the other hand Nessus takes the open ports into account and notifies you if these ports have potential security vulnerabilities attached

------------------------------------------------- Liquid–liquid extraction From Wikipedia‚ the free encyclopedia Liquid–liquid extraction also known as solvent extraction and partitioning‚ is a method to separate compounds based on their relative solubilities in two different immiscible liquids‚ usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase. Liquid–liquid extraction is a basic technique in chemical laboratories‚ where it is performed

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas

LIQUID CRYSTALS Introduction What are Liquid crystals ? Its History & Discovery Any of various liquids in which molecules are regularly arrayed like a solid crystal along one or two dimensions‚ but are free in the other dimensions as with typical liquids. Liquid crystals often display unusual and often manipulable optical properties such as anisotropic scattering. They can be divided into two classes‚ Thermo tropic(nematic‚ chiral nematic‚ and smectic.) and Lyotropic. Transitions to thermotropic

Laboratory 2 DRYING OF SOLIDS (Vacuum Tray Dryer) A Final Report Submitted to Engr. Luis K. Cabatingan Instructor‚ ChE 512L By Madeja‚ Rayam John D. July 31‚ 2012 1. Introduction Drying generally means the removal of relatively small amounts of liquid from materials. It is also defined as the transfer of liquid from a wet solid into an unsaturated gas phase. The goal of most drying operations is not only to separate a volatile liquid‚ but also to produce a dry solid of a desirable size
