Post-Lab Questions

1. Calculate the theoretical yield of the solid precipitate. Show your work.K2CO3 (aq) + CaCl2 (aq) → CaCO3(s) + 2KCl (aq)

2. Use Question 1 to calculate the percent yield of the solid precipitate. Show your work.

 3. Based on your yield of calcium carbonate, calculate the mass of calcium present in the original solution. 

 4. Analyze the data and use your yield of calcium carbonate to determine the experimental concentration of calcium chloride in the solution that you made in steps 6 and 7. Show all calculations and report in % wt/v concentration.Calculating the grams of calcium chloride that reacted:

5. Calculate the theoretical concentration of calcium chloride in the solution that you made up in steps 6 and 7. Show all calculations and report in % wt/v concentration.  

6. Using your answers from questions 4 and 5, create a bar graph comparing the theoretical to experimental percent concentrations of calcium chloride in the solution. Then, calculate percent error between the two concentrations.

Fraud detection using data mining?


Fraud Detection is the detection of fraud ( deceiving someone or an organization to gain something). With the technological innovations, fraudulent activities have become a common place. For example, forging checks, cracking passwords to gain access to bank accounts etc. These activities are causing huge financial and economical damages. With many fraudulent activities recorded, Data Mining can be used to find patterns in fraudulent activities which helps in detecting and hampering these activities.

Write a 5–10 page APA formatted paper on a business problem that requires data mining, why the problem is interesting, the general approach you plan to take, what kind of data you plan to use, and finally how you plan to get the data. You should describe your problem, approach, dataset, data analysis, evaluation, discussion, references, and so on, in sufficient details, and you need to show supporting evidence in tables and/or figures. You need to provide captions for all tables and figures.

Your paper should include an abstract and a conclusion and a reference page with 8–10 references.

Week 2 journal entry | NUNP 6650 – Psychotherapy With Groups and Families | Walden University

Assignment 2: Practicum – Week 2 Journal Entry

Learning Objectives

Students will:

Apply documentation skills to examine family therapy sessions *

Develop diagnoses for clients receiving family psychotherapy *

Analyze legal and ethical implications of counseling clients with psychiatric disorders *

* The Assignment related to this Learning Objective is introduced this week and submitted in Week 3.

Select two clients you observed or counseled this week during a family therapy session. Note: The two

clients you select must have attended the same family session.

Then, address in your Practicum Journal the following:

Using the Group Therapy Progress Note in this week’s Learning Resources, document the family


Describe (without violating HIPAA regulations) each client, and identify any pertinent history or medical

information, including prescribed medications.

Using the Diagnostic and Statistical Manual of Mental Health Disorders, Fifth Edition (DSM-5), explain

and justify your diagnosis for each client.

Explain any legal and/or ethical implications related to counseling each client.

Support your approach with evidence-based literature

Evidence based patient centered concept map


Assessment Instructions


You have been presented with a number of patient case files in the Evidence-Based Patient-Centered Care media piece. You reviewed each case, selected one case for further research, and created draft evidence-based concept map to illustrate an approach to individualized care for the patient. In this assessment, you will build upon and refine your draft concept map and develop a supporting narrative.

Create your concept map and narrative as separate documents. Be sure to note the areas where you need to include your evidence-based support and where you need to make clear your strategies for communicating information to the patient and the patient’s family.

Note: Many organizations use the spider style of concept maps (see the Taylor & Littleton-Kearney article for an example). Also, if a specific style of concept map is used in your current care setting, you may use it in this assessment.

Create your concept map and narrative as separate documents. Be sure to note the areas where you need to include your evidence-based support and where you need to make clear your strategies for communicating information to the patient and the patient’s family.


Note: The requirements outlined below correspond to the grading criteria in the scoring guide, so be sure to address each point. In addition, you may want to review the performance level descriptions for each criterion to see how your work will be assessed.

Supporting Evidence and APA Style

Integrate relevant evidence from 3–5 current scholarly or professional sources to support your assertions.

  • Apply correct APA formatting to all in-text citations and references.
  • Attach a reference list to your narrative.
Concept Map
  • Develop a concept map for the individual patient, based upon the best available evidence for treating your patient’s health, economic, and cultural needs.

Develop a narrative (2–4 pages) for your concept map.

  • Analyze the needs of your patient and their family, and determine how those needs will influence a patient-centered concept map.
    • Consider how your patient’s economic situation and relevant environmental factors may have contributed to your patient’s current condition or affect their future health.
    • Consider how your patient’s culture or family should influence your concept map.
  • Justify the value and relevance of the evidence you used as the basis of your concept map.
    • Explain why your evidence is valuable and relevant to your patient’s case.
    • Explain why each piece of evidence is appropriate for both the health issue you are trying to correct and for the unique situation of your patient and their family.
  • Propose relevant and measurable criteria for evaluating the degree to which the desired outcomes of your concept map were achieved.
    • Explain why your proposed criteria are appropriate and useful measures of success.
  • Explain how you will communicate specific aspects of the concept map to your patient and their family in an ethical, culturally sensitive, and inclusive way. Ensure that your strategies:
    • Promote honest communications.
    • Facilitate sharing only the information you are required and permitted to share.
    • Are mindful of your patient’s culture.
    • Enable you to make complex medical terms and concepts understandable to your patient and their family, regardless of language, disabilities, or level of education.

academic journals, newspapers, magazines, and books, as well as articles

posted on trustworthy websites. Wikipedia is useful, but does not count as

a credible source, neither does an online dictionary or its equivalent.

When writing, it’s a good idea to be as specific as possible; don’t make

generalizations. If you can, refer to and explore an original example in

which these issues are relevant:

What is Gestell? What is Bestand? What is the relationship

between Gestell and Bestand?
