The University of Adelide Experiment 8F Reduction Oxidation Chemistry HW
Question 1 a) Which metals from Table 8.1 are considered VERY ACTIVE (react with water and aqueous hydrochloric acid), MODERATELY ACTIVE (react with aqueous hydrochloric acid but not water) or have LOW ACTIVITY (do not react with either)? VERY ACTIVE: MODERATELY ACTIVE: LOW ACTIVITY: b) For the metals that reacted with water and/or aqueous hydrochloric acid, write out an appropriate redox reaction equation and assign oxidation numbers to ALL elements (HINT: Use Equations 8.10 and 8.11 in your laboratory manual in order to guide you). c) From your equations above, identify the species that are the oxidising agents and reducing agents in each redox reaction. Provide an explanation for your choices. (HINT: Think about the oxidation numbers of each element and how they change).Question 2 a) Why do we not test each metal against a solution containing that metal? What would you observe if you did? b) Using your results complete the following redox equations. If no reaction occurred, then write ‘no reaction’ like in Equation 8.8 of your laboratory manual. Mg(s) + Pb(NO3)2(aq) → Pb(s) + MgSO4(aq) → Equation 8.13 Equation 8.14 c) What is the oxidation number of magnesium on the left and right-hand sides of Equation 8.13? Has magnesium been oxidized or reduced? Explain your answer. d) Explain the outcome of the reaction in Equation 8.14. e) Complete the Metal Activity Series below by considering the numbers you wrote in the final column of Table 8.2 (ignore Metal ‘Pg’ for the moment). > > Metal Pg > > Most Easily Oxidised Least Easily OxidisedQuestion 3 a) Complete the Halide Activity Series below by considering the numbers you wrote in the final column of Table 8.3. (HINT: Refer to page 7 of your Manual for more information). > > Most Easily Reduced Least Easily Reduced b) From the Activity Series above, complete the following sentence: ″The ability to reduce elements in Group 17 _____________ as you go down the group.″ c) Based upon yours answers in Question 3a) and the periodic trend described in Question 3b), write out the full Halogen Activity Series below. Be sure to include Fluorine (F) and Astatine (At) in your answer. > > > > Most Easily Reduced Least Easily Reduced

Project Deliverable 6: Final Project Plan
This assignment consists of four (4) sections: a written project plan, a revised business requirements document, a project plan PowerPoint presentation, and the finalized project plan. You must submit the four (4) sections as separate files for the completion of this assignment. Label each file name according to the section of the assignment it is written for. Additionally, you may create and / or assume all necessary assumptions needed for the completion of this assignment.While taking all business and project parameters into consideration, make quality assumptions to support the following requirements.Section 1: Written Project Plan You are now in the final stage of the project plan development. All previous documentation should be combined into one (1) document that will serve as the statement of work for the project. Your goal is to have the project approved by the executive team. The project plan should be very detailed, which is appropriate to accomplish the monumental task of implementation; however, the executive team is only interested in a thirty (30) minute summation. Therefore, you also must create a compelling executive summary that is supported by your detail that convinces the executive team that it should move forward with your solution.Develop a thirty to forty (30-40) page project plan in which you:Write a five to ten (5-10) page executive summary in which you provide a high-level technical overview of your project where you address the following: Describe the scope of the project and control measures.Describe the goals and objectives of the project. Give a detailed, realistically estimated cost analysis of the entire project, including technical resources (human capital) that may be needed to complete the project.Relate the value of the project plan solution to the competitive advantage that information technology will afford the organization.Provide all aspects of the information technology implementation into the project plan.Recommend solution providers who can assist with development and implementation. Include a cost analysis of at least three (3) providers.Combine all previous documentation for Project Deliverables 1-5 in which you:Provide all aspects of the information technology implementation into the project plan. Revise the documentation based on feedback from the earlier evaluation of the deliverable.Use at least five (5) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.Your assignment must follow these formatting requirements:Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.Include charts or diagrams created in MS Visio and MS Project as appendix of the Word document. Make reference of these files in the body of the Word document. Section 2: Revised Business Requirements DocumentDocument all revisions made to the written project plan in the Document Control section of the business requirements document from Project Deliverable 2: Business Requirements. Note: This documentation must outline the revisions made to the previous deliverables required in Section 1: Written Project Plan.Section 3: Project Plan PowerPoint PresentationAdditional to your detailed executive summary you must present your findings to the executive team and the venture capital group that along with the executive summary will convince the group that your solution is optimal.Create a ten to fifteen (10-15) slide PowerPoint presentation in which you:Illustrate the concepts from the executive summary in Section 1 of this assignment. Create bulleted speaking notes for your presentation to the executive board in the Notes section of the PowerPoint. Note: You may create or assume any fictitious names, data, or scenarios that have not been established in this assignment for a realistic flow of communication.Use a professional technically written style to graphically convey the information.Section 4: Finalized Project PlanUse Microsoft project to:Finalize your project plan from Project Deliverable 5: Network Infrastructure and Security to include all necessary changes in assumptions, tasks, and / or subtasks.Harness all previous done project that u have handled for me as i explained to you from the inception. Follow the instruction as stated to the letter. Pls i need maximum points here, give it ur best, thank you. PLs don't ask for more money. U have been handling all of them.

irradiated and genetically modified foods, biology homework help
The Discussions are not simply statements of opinion. They are intended to allow you to expand upon and apply the principles discussed in your textbook, the lectures, and/or other research you conduct. Each week a question will be posed for your consideration. Before answering, you should review the chapters covered during this week and the lectures.Many of the farm-grown/farm-raised foods available today have been treated with pesticides. Meats, which we eat like beef and chicken, have been irritated. Why are radioactive substances like Cesium 137, Cobalt 60 and Plutonium 238 used to irradiate our food? Some benefits are radiation kills bacteria, the nutrtitional value of the food is preserved and food spoilage is reduced and food shelf life is extended. However there are negative side effects of this technology that everyone must be aware of and understand. For the Week 2’s Discussion we will be talking about Irradiated and Genetically Modified (GM) foods. When discussing this topic in your initial post the following points must be addressed:Irradiated foods1. Discuss a farming practice or treatment practice used to treat crops, crop products, raise animals or treat meats.2. What are some of the reported effects of the treatments on people? [Sources of information must be reliable and credible scientific resources.]3. How are these practices being monitored by the U.S. Federal Government?4. How can the general public research how their food is grown?Your initial post to the discussion is required to be completed and posted by 11:59 p.m. ET Thursday of Week 2. Your initial post is required to be on a specific radiation or genetically modified process that has NOT been posted on by another student AND at least 250 words. This MUST be in your own words. You are required to include at least one credible and reliable scientific resource of information ONLY and research carefully. Do NOT use ANY open blog or ANY open source where anyone can post responses and the information is not verified. Please do not plagiarize. Properly cite information used from outside resources per APA with in-text citations immediately following the information and a full reference citation at the end of discussion post. Review the “Credible References/APA format” folder in the ‘Start Here’ area of the classroom for additional information on Researching Information and properly citing resources used.You are then required to make at least two additional posts to two other students [or one student and the professor] on two separate days and not posted on the same day as your initial post. The response posts should be at least 100 words and be substantive in nature. If a reference is used in writing a response post, it must be an appropriate and reliable academic resource as it is with references used for the initial discussion board response. While pleasantries such as "I agree" or "great job" are nice, they will not count as one of your required posts. A complimentary, philosophical, or off-topic comment does not count as one of the three required entries. For example, it does not help us to tell us that you did not know something before you read an entry. All entries should help everyone understand one or more of the concepts presented.
