Description I only need you to do the Audio ok. I completed the PowerPoint already see Attachment. Assignment 3: The Presentation Objective: Develop an audio-narrated PowerPoint presentation based on the research you have conducted about your chosen molecule/substance. Assignment Instructions: Using the course project steps completed to date, you will develop your presentation based on the work you submitted for Assignments 1 and 2 as well as the feedback you were given. To prepare for this assignment, I recommend that you do the following: Read these directions carefully. Review the grading rubric. The grading rubric is a detailed evaluation that I will use to assess your performance. It will also help you understand what is expected of you as you prepare your assignment. Message me with any questions! Presentation requirements: Your presentation will be submitted as an audio-narrated PowerPoint. For instructions on how to create audio narration in PowerPoint, see the following link: Record a Slide Show With Narration. Audio narration is a requirement! There must be a visual element (e.g., photos, videos, graphs, figures). Your presentation must contain approximately 10-15 slides (excluding references) and run approximately 5-10 minutes. Please note that less than 10% of your presentation should contain direct quotes. Proper use and pronunciation of scientific terminology are required. For help with pronunciation, see this link: Cambridge Dictionary Be sure to properly cite your work, both internal to the presentation as well as within the reference slide (this includes photos, graphs, figures, videos, etc.). All references listed on the reference slide should be cited internally within the presentation, and vice versa. You will submit this presentation to your classmates to review and discuss as a part of the Week Eight Forum. The required elements: Your presentation should contain the following elements in the order listed below. In addition, I expect that any feedback provided to you from Assignment 1: Annotated Bibliography and Assignment 2: The Outline be incorporated into this assignment. Please go back and review those comments. Introduction Slide(s) - ALL Molecule/substance Introduction The common and IUPAC name of your molecule/substance. Please see this link to help with scientific names if needed: IUPAC Nomenclature Of Organic Chemistry: https://www.acdlabs.com/iupac/nomenclature/ Where you can observe your molecule/substance in society and/or in nature. A brief discussion on why you chose your molecule/substance. If possible, a picture and/or video of you safely observing your molecule/substance in the field. If you cannot safely observe it, please include a couple of images from the internet. Description Description You must include a physical description. You can use your personal observations from photographs. If you cannot safely observe your molecule/substance, you must research. Physical Characteristics (appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, etc.) Chemical description: You will need to research the chemical properties of your compound/molecule) Chemical Characteristics (stability in air or other environment, flammability, volatility, etc) Discovery a. Describe the initial discovery of your molecule. Who discovered the molecule, when, how, etc? Some compounds are part of a larger substance/plant. If this is the case, describe the isolation of your specific compound. The isolation refers to the initial time your molecule/substance was discovered from its raw materials, or isolated from its natural resources. Please see here for some hints on the chemical isolation. Usage and Benefit or Harm to Society Where has your molecule/substance been used. Is it used regularly or is has it only been used on occasion? If your compound is one we ingest when eating, include information on foods it's commonly found in. Write about the Benefit or Harm to Society Caused by your molecule/substance. Many compounds can be used as bioweapons or have both positive and negative impacts. Other compounds have had benefits as medicines or have caused harm as illicit narcotics. All of these are good ideas to start out thinking about, so I'd like you to discuss these impacts on society, the future, and in any way you can think they may be beneficial or harmful. Conclusions - ALL This section must contain: Four to six points that sum up the main topics of the presentation that you have in your outline Reference Slide(s) and Internal Citations – ALL This section must contain: Internal citations - This is not just a separate section; rather, referencing should occur throughout the presentation via parenthetical citations anytime you paraphrase, make direct quotes, or use visual components from other sources. Please be sure to cite any language, images, videos, etc. in the presentation that should be cited. Reference Slide - Your presentation should also have a final reference slide listing 5-10 credible sources researched for your presentation. NOTE: these are not included in the slide count for your presentation. Do not include your summary/evaluation from Assignment 1: Annotated Bibliography; simply list the references utilized in your presentation in APA format on the reference slide. Additional Resources: Presentation Tips and Guidelines APA – In-Text Citations: The Basics APA – Reference List: Basic Rules Sample_Presentation (Keep in mind that this is a sample presentation for biology using a format other than PPT with audio; PowerPoint with audio is the required format for your presentation) Evaluation: Please review the Presentation Grading Rubric that describes how your presentation will be graded.

Description Open the Excel Assignment Spreadsheet attached.In that file on separate pages you will find pages labeled. (I have finished the Acid Base Titration, and started the Alkalinity but having trouble finishing it and with the rest). I also provided examples for the standard addition and linear regression part. Acid Base Titration – On this page, plot the titration curve, 1st derivative and second derivative for both the weak and strong acid titrations (6 graphs total) The graphs should meet the proper format for figures.Create a table with the end point estimates for both titrations by the three separate graphs.That is the endpoint from the titration curve, 1st derivative and second derivative plot for each.6 entries Alkalinity – Plot the titration curve and 1st derivative.Are these graphs useful?Plot the 1st Gran function Vol total * 10^(-pH) versus Voltitrant. Refer to Gran document from USGS.Determine the x intercept, the bicarbonate endpoint. Standard Addition – Determine the amount of Fluoride in the sample using a standard addition plot.You can use the excel files in this folder as an example. Linear – Determine the slope, the intercept, the concentration of the unknown, and the error in the analysis for the concentration at a 95% confidence interval.Use the excel files provided as examples. Solution Prep – Create a spreadsheet that calculates: (a) The weight of MgCl2 required to create 1 kg of 1000 ppm Mg ion; (b)The weight of the 1000 ppm stock solution required to create a 15.0000 g of a 100 ppm sub-stock solution.

Description Someone at Tesla stole your idea for a better electrolyte solvent and got all the credit. You decide to get out of the cutthroat battery industry and try nuclear chemistry. You get a job in the bowels of the Smithsonian Institute performing radiometric dating. Do some research to become familiar with the job before you start. Write a review about carbon-14 dating that includes the following subtopic. Use the following guidelines for your review. Meets the 100 word minimum requirement for each subtopic. Images need to be referenced, even if you created them. Entry is written in a formal manner, with no use of text messaging “shorthand,” slang, or similar. Only reliable references are used and all quoted data is referenced properly with correctly formatted citations. Do not plagiarize! a. A review of the principles of carbon-14 dating, including the nuclear reaction and the limitations on how far back carbon-14 dating can reliably measure the age of something. b. A rare find of carbon containing soft tissue (biological tissue, such as proteins) in a T-rex dinosaur fossil bone that is thought to be 65 million years old has recently been discovered by paleontologist Mary Schweitzer (Fields 2006). You have been asked to analyze a sample of the tissue for carbon-14 dating. The activity of the sample was found to be 8 x 10-5 disintegrations per second. An equal mass of fresh sample of human tissue was found to be 15.200 disintegrations per second. The half-life of carbon-14 is 5700 yr. Calculate the age of the dinosaur tissue from the data you acquired. c. Is the date you calculated above valid for this type of analysis? Why? d. Read the paragraph below. Does your finding support, refute, or not do either for Creationist theory? Explain why. “Young-earth creationists also see Schweitzer’s work as revolutionary, but in an entirely different way. They first seized upon Schweitzer’s work after she wrote an article for the popular science magazine Earth in 1997 about possible red blood cells in her dinosaur specimens. Creation magazine claimed that Schweitzer’s research was “powerful testimony against the whole idea of dinosaurs living millions of years ago. It speaks volumes for the Bible’s account of a recent creation.” Fields, Helen. "Dinosaur Shocker." Smithsonian.com. Smithsonian Institution, 01 May 2006. Web. 14 July 2017. http://www.smithsonianmag.com/science-nature/dinosaur-shocker-115306469/. e. The T-rex soft tissue needs to be extracted with a strong ammonia buffer. Calculate how many grams of sodium hydroxide you need to add to one liter of 0.75 M ammonium chloride to prepare a pH 9.5 buffer solution. (pKb of ammonia = 1.8 x 10-5)
