Solubility‚ Crystallization and Melting Point Determination Post-Lab Discussion Guidelines: Part 2A and 2C: Draw tables (as in textbook) showing which combinations were soluble/miscible and which were insoluble/immiscible. Explain why this is so. Why are certain chemicals soluble/miscible when others are not? Part 3A: Calculate % recovery (this is not the same as % yield – see handout from the first day of lab if you’re confused)‚ and determine melting point of your product. Discuss % recovery

Lab 6 Report Part A 1. Run your model. Compare the queue statistics of the 3 processes with those obtained for Part C in the previous Lab. How have they changed and what conclusions can you draw? (Note the sums of all capacities for both cases are equivalent – 12 in each). The queue time and number statistics for the Air Jordan Logo operators and the Air Max Logo Operators were relatively close. The average queue length for the Air Jordan Logo operators was 0.03769112 in the previous lab

This experiment called for determining the salinity through mass. To determine mass‚ a small‚ cleaned watch glass was labeled with the sample number on the bottom using a permanent marker. The watch glass was weighed in grams. 2 mLs of the sodium chloride solution was pipetted into a 10 mL graduated cylinder that would be transferred to the watch glass. After this transfer‚ the watch glass and sample were reweighed and recorded. To figure out the mass of the solution‚ the

LAB 12 Introduction In this lab you will use the Wireshark packet analyzer to capture and display the control information and data stored in packets transmitted over a network. Wireshark collects network traffic data and creates files that display packet header information in a layered format like that used by the Internet model. These layers can be expanded to view details that may prove helpful in determining the source of problems that your network might be experiencing. Creating filters that

Seed Lab I. Purpose/Question: A. What is the variable you are testing? Radish seed vs. Pea seed B. Question 1: How does seed type affect when the seeds germinate? C. Question 2: How does seed type affect the length of the stem? II. Research: List two pieces of information you learned about the variable you are testing below. The radish stem was longer. Both seeds germinated equally fast. III. Hypothesis: Make these an “If-then” statement and do not use pronouns (I‚ we‚ he‚
