The purpose of this lab was to determine the formula of copper chloride hydrate by dehydration through heating, rehydration through adding water back in, the reaction of aluminum with the copper chloride hydrate to produce solid copper, and the weight of this copper. To accomplish this, a petri dish was weighed and 1.01 g of copper chloride hydrate was added to the dish. The solid salt crystals were broken up to make sure that all of the hydrate would be heated the same. Next, the petri dish and hydrate were heated upon a hot plate for roughly 15 minutes, until all the salt crystals were brown instead of blue. This indicated that all of the water had been burned out of the hydrate, leaving dehydrated copper chloride.…

Process To Make Copper Coated / Plated Nails 1) Measure out 1/4 cup white vinegar and put into the glass bowl. 2) Add 1 teaspoon salt. Stir salt until it dissolves in the vinegar. 3) Take a penny and submerge it into the vinegar solution 1/2 way for 10 seconds.…
During my IPPE rotation, I was fortunate enough to be able to work at Publix pharmacy with Dr. Rita Brown. Publix Super Markets Inc. was opened on September 6, 1930 by George W. Jenkins in Winter Haven, Florida. By 1945, he acquired a warehouse and owned nineteen All-American stores from Winter Haven to Lakeland, Florida. Mr. Jenkins based the mission of Publix Super Market, on the standard of clean stores, friendly service, quality merchandise, and always putting people first. The first Publix pharmacy was opened in Orlando, Florida in the 1986.…
Lab 2 Summary In this lab, the purpose was to understand how to use a DMM to measure different things like resistances, current, and voltages as well as how to successfully comprehend the electrostatic relationship between various objects. In the first part of our lab we learned how to use a Digital Multimeter by using a simulator to draw diagrams of circuits. This helped give us a basic understanding that when dealing with a circuit and tools like a DMM, you have to connect wires to certain places and make sure the positive is touching the positive side. In the second portion of the experiment, we learned how to use the equipment that will be used for the other labs.…
The presentations for Unit 0 were focused on introducing yourself to thee class. Each student’s presentation I watched covered all the topics of background, occupation, education, interests, and course goals. I chose each presentation strategically to learn more about each student because they were not in my HSEM class last semester. Steel Mcneil is currently a captain with Kodiak Fire Department with a background in the fire service throughout high school and college. He is taking this class to continue to complete his bachelor’s degree in Homeland Security and Emergency management.…
Does it Screen? Alexander Hamm Period 2 Ms. Ulrich 11/29 (Graphic that represents the lab) Abstract: My experiment is about testing which brand of sunscreen works best, Equate, Banana Boat, or Coppertone.…
Students, Thank you for coming to lab today. I hope to make our communication as clear as possible to facilitate your success in the lab. Below are some action items for you to consider as we move into September. There will be no lab next week (9/4) but there are items due before we meet next. Experiment 0…
Percent Copper In Brass Lab Conclusion Emily Oleisky The purpose of this lab was to observe the amount of light a solution absorbs, and use the relationships in the Beer-Lambert Law to determine the quantity of a certain compound within a complex sample. First, the relationships between wavelength, concentration, and absorbance were determined. This lab focused on identifying the absorption of copper in various brass samples, and finding the percent copper in brass. In the first activity of the lab, the scientist was trying to determine the difference in molar absorptivity across various wavelengths of multiple salt solutions.…
Include information that you have learned in this unit, such as what particles are, changes of state, definitions, clues that physical or chemical changes have occurred, etc. They need to have enough information that they can figure out which demonstration is a physical change, which one is a chemical change, and why. It would also be very helpful to give them a summary of clues that physical or chemical changes have occurred. Lab Report: Buddy Lab - Physical and Chemical Change Question: Sugar: Is this a physical or chemical change? What will happen if I heat up sugar and water together?…
Sarah Bounab BQD Experiment 2: Copper/Iron Stoichiometry Abstract: The purpose of the Copper/Iron Stoichiometry lab was to determine which of the two possible iron sulfate compounds formed when reacting aqueous copper(II)sulfate with solid iron metal. The techniques used in this lab were weighing by difference, quantitative transfer, and vacuum filtration. At the end of the experiment it was found that iron was the limiting reactant and iron(II)sulfate was a product of the reaction between 7.0002g of copper(II)sulfate and 2.0101g iron metal which produced 2.3037g of copper product with a percent yield of 100.72%.…
Purpose The purpose of the experiment that the students are conducting is to determine the empirical formula of the copper chloride hydrate by the data that has been collected throughout and that will allow the students to “investigate the effect of heating a hydrate salt” (Sanders). This will be achievable after finding the masses of chlorine, copper, and water. Introduction In this experiment, the students are using the law of multiple proportions to find the chemical formula for the compound (Sanders).…
Hello, is it okay if I record this session? Participant 1006: Yes, it is.…
The students were asking questions about safety and what they should be aware of. I appreciated having the background knowledge to be able to have a conversation like this with my students. I want to take the knowledge I gained and share it with parents, students, and/or staff as appropriate. The important thing to take away from workshops is information to share with others. As a leader, I will continue to be a lifelong learner and take the information I learn and pass that on to my staff.…
For this rotation I taught the Real Care Baby lesson. IN this lesson the students watched a visual video that gave them an overview of what the Real Care Baby is all about. Then they got pulled out in groups to complete the “one Minute” baby challenge. This challenge required the students to stop the baby from crying in one minute. This required following directions, collaboration, completion of the challenge, and critical thinking skills.…
