Description
In 1-2 pages, using APA-style formatting, provide an explanation of the meaning of the first and second laws of thermodynamics. Then, using the second law, explain why a barrel of oil can be used only once as a fuel source, or in other words, why can we not recycle high-quality energy resources

ASU Wk 7 Medical Necessity Job Aid Margin Reflex & Digital Photos Worksheet
This exercise will be presented in class
Please note: to carry out the exercise you will need a magnifier (or you can use your cell phone as one), a masonry nail or a steel pocket knife/any dull knife, one copper penny and 1/2 cup of white vinegar.
You have 4 minerals in your set: calcite, quartz, feldspar and hematite. Use the testing for hardness, luster, breakage and reactivity to identify your minerals. Use this link to upload your exercise on mineral identification. You can submit your work for feedback before the final submission.

CHEM 141 Grossmont College Calorimetry Lab Report
Lab Report: Calorimetry
Purpose:
The purpose of the Calorimetry experiment is to introduce you to application of thermochemistry. The purpose of writing the full lab report for Calorimetry experiment is to prepare you to write technical papers for journals, grants for funding, and learn to communicate scientific information to peers and the general public.
Skills:
In this lab report, you will:
Analyze the data provided to you.
Compose a full formal lab report (title page, objective, introduction, procedure reference, results and calculations section, discussion, and conclusion).
Knowledge:
This assignment will also help you to become familiar with the following important content information:
Calorimetry
Writing a complete lab report
Tasks:
This exercise asks you to collect, organize, analyze, and evaluate data you collected in the lab. You will type a lab report that includes the following:
Title page
Objective
Introduction
Give the logic of the experiment.
Be sure to define key terms and all applied experimental equations (e.g. calorimetry, calorimeter, enthalpy of formation, heat capacity of calorimeter, heat, balanced chemical equations, Hess’ law, and percent error.).
Procedure Reference
If there are any changes to the published procedure be sure to note them here.
Results and Calculations section
Table summarizing
Your major experimental data (e.g. heat capacity of calorimeter, experimental heat of formation for Mg2+ & MgO, actual heat of formation for Mg2+ & MgO, and percent error)
Be sure to include the PDF with the data that you were provided when you turn in your report.
Graphs
Since data was given to you, you can use the graphs that were provided. You do not need to make graphs. Just paste them into the appropriate section of the report.
One sample calculation of each type.
Spreadsheet
Discussion
We did not record the boiling and freezing point of water experimentally. But issues with these measurements could possibly be something that would cause error in this experiment. Perhaps something related to this would provide one of your sources of error?
State the heat of formation for MgO and describe any errors that may have led to an incorrect value of either the heat of formation (Mg2+ or MgO) or the calorimeter constant.
Conclusion
Reiterate the major experimental data.
Your report will also include:
prelab
be sure to look over the comments from your instructor and correct any mistakes
changes to the published procedures
experimental observations
quantitative observations (aka numerical data)
qualitative observations
running log

CWU COVID-19 Essay
The senior leadership of your organization is preparing for its annual three day meeting. During these meetings, one day is devoted to current events / issues which the company finds itself needing to address. For this year's meeting, you have been asked to give a presentation on Cybercrime as a strategic threat to the organization.
To prepare for your presentation, you should find a recent news report or law enforcement press release about a specific instance of a cybercrime which impacted the financial services industry (or customers). Analyze the report / press release and then write a background paper containing your analysis and findings.
In your background paper, include a summary of the report or press release that addresses the crime, the perpetrator, motive (if known), methods, the victim(s), the object of the crime (systems, data, networks, etc.), and the outcome of the investigation / prosecution. (Who did what to whom? What happened?)
Should the company take actions or develop strategies to protect itself from similar crimes? What are your recommendations in this regard
