pH Scale by the Method of Successive Dilutions Paper
Objective:It is fairly common knowledge that neutral water has a pH of 7, acids have a pH <7 and bases have a pH>7, but few people understand this in terms of the actual hydronium ion concentration. Our objective is to develop an understanding of logarithmic scales by developing a pH scale Background: The pH scale describes the hydronium ion concentration in aqueous systems pH = -log[H3O+][H3O+] = 10-pH = 1/10pH The Method of Successive Dilutions is an experimental technique for preparing a series of solutions of different concentrations from one volume of stock solution. Lets look at a series of half dilutions. With the virtual lab fill 5 flasks with a constant amount of water (less than half the volume of the flask), for simplicity, we will use 20 ml, but any amount will do. *Virtual Lab Tip* – Right Click on each flask and label it Now add the same amount of stock 1M HCl to the first flask (20 mL), and note that the concentration has been diluted in half, [H3O+] = 0.500M or 1/2 (1/21) the original molarity. From this flask transfer 20 mL to the second flask and note the it has been diluted in half again,[H3O+]= 0.250M or is one fourth (1/22) the concentration of the original stock solution. ( one screenshot here)Repeating this procedure with the remaining 3 flasks gives: 3rd dilution: [H3O+] = 0.12500 or 1/8 (1/23) the original stock molarity (one screenshot here)4th dilution: [H3O+] = 0.06250 or 1/16 (1/24) the original stock molarity (one screenshot here)5th dilution: [H3O+] = 0.03125 or 1/32 (1/25) the original stock solution. (one screenshot here)Lets look at this in more detail: [H3O+] = 2-n = 1/2nWhere n is the number of successive dilutions and by using a dilution factor of one to two, you have come up with a log base 2 scale. Question: Would changing the volume of the original stock solution and the incremental dilution volumes to a new constant value effect the successive concentrations. Say by starting with 10 mL and transferring 10 mL increments? If you say yes, repeat the above with 10 mL increments and explain. ANSWER THIS QUESTION IN COMPLETE SENTENCES. NO PLAGIARISM.

Cultural Anthropology Film Review
In your review you should answer the following questions (3 points for each):1. What is the main message– or narrative arch (story)– of this movie? In other words, what is this movie about? Is it a fiction or a documentary?2. Use anthropological key terms in your description of the movie. For example, if this movie deals with gender identity (Such as Pricilla Queen of the Desert) use terms from Ch. #8 (Gender) in the Guest textbook to explain the movie. If this movie has an ethnocentric perspective about the culture it depicts, cite a scene or quote from the movie to prove it. How does this movie deal with aspects of symbolic culture (such as religious beliefs, practices, gender rules, ritual, or issues of social inequality, class, cultural capital, etc.)3. What are your feelings about the movie? Do you agree or disagree with the directors portrayal of the culture? Would you recommend it to a student taking Cultural Anthropology?Link the film “lost in translation cut” Link the film “Margaret Mead and Samoa (1988)”

A Medical Practice Problem Response
******** please respond to the discussion below add citations and references 🙂 *********A medical practice problem is more about disease or medical condition, while a nursing practice problem deals with human response to potential health problem (Cooke, A. Smith, D., & Booth, A. 2012). For example, a medical diagnosis of Stroke or CVA, provides information about the patients pathology. The nursing diagnosis for this medical diagnosis will be Impaired speech and more, which provide holistic understanding of the impact stroke can have on a person or family life. PICO (alternately known as PICOT) is a mnemonic used to describe the four elements of a good clinical question. It stands for: P- Patient/Problem, I- Intervention, C- Comparison, O- Outcome, T- Time (GCU, 2018). It is important to ensure your PICOT is based on a nursing practice problem, because PICOT help solve a problem by analyzing, intervening and having a measurability.References:Cooke, A., Smith, D., & Booth, A. (2012). Beyond PICO: The SPIDER tool for qualitative evidence synthesis. Qualitative Health Research, 22(10), 1435-144 Chapter 1 in Nursing Research: Understanding Methods for Best Practice.
