Chemistry Questions

 All work must be original and authenticity is checked.

Discussion Topic 1: Chemistry In Its Element (Podcast): https://www.chemistryworld.com/46.more
 

There is a lot of chemistry going on all around you. If you start  to observe a bit more intentionally, you will notice many new discoveries, articles, news stories, and breakthrough research happening everyday. And science can only be useful and keep moving forward if it is shared. 

For this topic, I want you to find a session of Chemistry In Its Element Podcast that is interesting to you and share it with the class. In your post, please include the following:

1. A proper APA citation of your podcast, including a direct link to it that we can visit.

2. A sufficient summary of the podcast in common language that could be understood by the general public.

3. Its implications for society, benefits, drawbacks, practicality, etc. This is where you discuss your personal thoughts regarding the podcast. 

4. Questions to your classmates that invite discussion and further the dialogue.

5. An embedded picture that is relevant to the discussion.

13.3.2 CIA Demonstration: The Synthesis of Nylon 
Question 1 of 13

What   is the name of the type of reaction that you see in this demonstration?   Describe IN YOUR OWN WORDS what happens, generally speaking, in this type of   reaction. Be detailed in your discussion.

There are two chemicals used in this reaction, 1,6-hexadiamine (which is in a water solution) and adipoyl chloride (which is in a hexane solution). Think back to what you learned in this course about solutions and intermolecular forces. Why don’t these to “mix” together (in other words, make a homogenous solution) when combined? Why do they separate into layers? Be clear and detailed in your response.

15.1.7 CIA Demonstration: Titrations

Where would the hydrogen ion (H+) [or the hydronium ion (H3O+)] and the hydroxide ion (OH-) come from?

Thinkwell videos 
15.1.7 CIA Demonstration: Titrations

Suppose I wanted to calculate the pH of the acid used in this titration. The acid used in this specific example is a weak acid, which would normally require a more laborious mathematical approach to find the pH—one that is not covered in this class. However, for this question just assume that it is a strong acid in order to make the calculation easier as shown in your text. 
 

How (explain) can I use the results from this experiment to do this? What would the pH be in this case? Show all work.

Sports Psychology Power Point

PowerPoint Presentation dos and don’ts:

–Include a notes section in the actual notes section of the PowerPoint which should be basically word for word what will be said during the presentation.

–Do NOT use crazy slide transitions or background colors. Keep the slide transitions simple and background colors and slide layout must be appealing and able to be easily viewed by all audience members no matter where they are in the room.

–Use bullet points on the actual slides, use the notes section for your verbiage. Do NOT have slides, which end up being read verbatim for the presentation.

–DO include a reference page (in APA format).

provide a definition of the terms: “conceptual definition” and “operational definition”.

APA formatting should be used throughout (cover page, running header, major heading, subheadings, in-text citations, and reference list). Any time you paraphrase or directly quote a source, in-text citations should be used.  A full APA-formatted reference should be included at the end of the assignment. Academically, no more that 20% of the essay should be quoted. At least 80% should be in your own words.

INSTRUCTIONS:  Make sure to follow the directions in order.

First, provide a definition of the terms: "conceptual definition" and "operational definition".
Next, conceptualize and operationalize the variable “race.”
Read the Census Bureau’s report on race at: https://www.census.gov/content/dam/Census/library/publications/2011/dec/c2010br-02.pdf.
Answer the following questions after reading the report:
What changes did the Bureau make to the conceptualization and operationalization of race in the 2000 census?
Why did the Bureau make these changes?
Could the difference in operationalization produce different conclusions about race?
Does the Bureau’s conceptualization and operationalization of race coincide with yours?  If so, how?  If not, what is different
its not as long as it seems. it really can be accomplished in 600 words. when answering in the essay please include the question.

English Papers

Reflect upon the literature and share how 1 of the literary pieces, characters, or authors studied in this course can be used as a Christian witness or salvific tool to fulfill the Great Commission. Identify the title, character, or author of the chosen literary piece and begin with a cogent thesis statement; offer detailed support and show control over the topic.

 

Story: Everyman

 

Example:

   Everyman can be used for Christian witness in a materialistic society because of the theme of an unavoidable reckoning with God. Firstly, in a materialistic society, people assume their worth in earthly commodities with no thought of the afterlife. Death is not recognized by Everyman because he is consumed with his wealth and even attempts to bribe death to delay. This drama causes an awakening that money cannot buy eternal life.

         Secondly, Everyman possesses the Biblical concept that every man dies and has to give an account alone before a righteous God. Everyman tries to find traveling companions with many declining his offer. Death is unavoidable and the outcome is hopeless apart from the grace of God in Jesus.  In conclusion, Everyman is profitable in Christian witness because of the themes of a reckoning before God and mankind's hopelessness apart from the grace of God in Jesus.

Sports Psychology Power Point

Congratulations. You have been asked to create an MS PowerPoint presentation (i.e., Week 7 assignment) in order to educate youth sport coaches and/or strength and conditioning coaches about sport psychology.  

Suggestion – select a specific topic of interest, which is presented in our PSYC460 assigned readings. Examples include: Goal Setting, Imagery, Stress Management, Group Cohesion, or Exercise Adherence.

Create a MS PowerPoint (PPT) presentation and include notes within the presentation. The Notes section should be the script you will use for your presentation such that if you were unable to make the presentation, someone else could present the information by reading what you’ve written in the Notes section. Additional Information re: MS PPT Notes is discussed later in the assignment's instructions. 

The Sport Psychology presentation must be at least 10 slides in length (not including the title and reference slides) and include components such as the following: 

Title
Table of Contents
Primary Topic of Presentation
Introduction of Presentation’s Main Objective(s)
Identify and Define Important Psychological Concept(s) associated with Presentation's Objectives
Explain how these Psychological Concept(s) can influence athletic performance (cite information from at least three (3) academic publications [i.e., journals – (e.g., The Sport Psychologist, Journal of Sport and Exercise Psychology)]. — Suggestion – You can use the APUS Library (see "APUS Library" on PSYC460 home page) in order to locate scholarly publications (e.g., academic journals). "SPORTDiscus with Full Text" can be a useful database when completing your literature search.
Present one (1) web link for a video pertaining to Psychological Concept(s) discussed in presentation. — When identifying the video in the presentation, just insert the web link on the slide. APUS has size restrictions on uploads, and incorporating the video into the presentation will often make the PPT too large.
Identify an activity, which individuals can complete during this presentation in order to gain knowledge about Psychological Concept(s) discussed.  
Conclusion
References (as well as in-text citations should be displayed in APA format). In-text citations may be included within the Notes section of each slide. Information re: American Psychological Association (APA) format is presented in this course's Resources or www.apastyle.org. Also, a suggestion – visit the APUS Library to review Writing@APUS (see "APUS Library" tab located on left side of course's home page).
Please be sure to review the MS PowerPoint do’s and don’ts document (see attachment). Remember, the MS PowerPoint must include a Notes section. 

Additional Information re: Notes section:

Notes are placed on the same slide (i.e., beneath) information being presented pertaining to a specific area (e.g., Introduction). See "Click to add notes" at bottom of slide – notes will be placed in this area. Suggestion – use MS PPT "help" to review instructions for inserting “speaker notes” using your specific version of MS PPT. 

If Notes are not included within the same slide, a 10-point deduction will be assessed prior to reviewing a student's submission.

Here is an example:https://support.office.com/en-US/article/Create-speaker-notes-fc59586b-888f-4ebf-ab07-8a3cc8297867

Please review "More Tools" (see tabs on left side of course's home page) to review policies concerning Plagiarism.

Please submit your assignment as an attachment (in an MS PPT ppt. or MS PPT pptx. file format)  titled "Your Last Name Week 7 Assignment." For example, the MS PowerPoint file would be titled: Johnson Week 7 Assignment. Avoid typing your entire assignment in the text box provided within each assignment.
