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

The study of urinary chemistry on stone forming minerals will provide a good indication of risk of stone formation. Urinary supersaturation with respect to stone-forming constituents is generally considered to be one of the causative factors in calculogenesis. Though supersaturation of stone forming salts in urine is essential‚ abundance of these salts by itself will not always result in stone formation. Various substances in the body have an effect on one or more of the stone forming processes (nucleation

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

Objective: The purpose of the lab is to learn filtering techniques. Specifically‚ to form and filter a calcium carbonate precipitate using a Buchner funnel. Procedure: a.) Prepared a mixture of .5 M calcium nitrate (45 mL) and .01 M sodium carbonate by combining and stirring the two liquids in a beaker. Allow the mixture to stand. b.) Prepare the filtration assembly. The assembly consists of a tapered flask with a buchner funnel inserted in the top. The funnel has a rubber stopper attached

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

Chapter 5 Notes The study of energy and its transformations is called thermodynamics. An aspect of thermodynamics that deals with the relationships between chemical reactions and energy changes involving heat is called thermochemistry. 5.1 The Nature of Energy Energy is defined as the capacity to do work or produce heat. Work is the energy used to cause an object with mass to move. Heat is the energy of an object that causes its temperature to increase. Kinetic and Potential Energy
