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

Lab 5: Osmosis Purpose: The purpose of this lab is to familiarize you with osmosis and‚ specifically‚ what happens to cells when they are exposed to solutions of differing tonicities. Hypothesis: If we add higher concentrations of sugar to the dialysis tubing‚ then the net movement of coffee into the dialysis tubing will increase. Materials scale or balance 24" dialysis tubing 4 transfer pipets sugar scissors rubber bands four coffee cups - they need to be roughly the same size

Lab 5: Ethernet LANS Exercise 5.1.1 The IEEE standards cover more than just Ethernet. The 802.3 standard actually builds upon the 802.1 network architecture standard from IEEE. Briefly define the 802.1 standard and what it provides. Use your textbook and the Internet to research your answer. A: The 802.1 standards provide LAN/MAN management. The 802.1 standards where created by the close of the 1970’s. Exercise 5.1.2 The 802.3 family of standards has the format 802.3x where x is a sequence of letters

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
