Many things in nature, also used in one’s daily life, the medical field, and/or industry, are compounds that contain polyatomic ions. Visit Polyatomic IonsLinks to an external site. and read about what the characteristics of a polyatomic ion are and how useful they are in everyday life.
Look in the readings this week (your book or papers) or refer to your experience, and identify a compound that is particularly interesting to you. Include the following in your initial response:
The formula
The name
The use
Where it comes from (if it can be found in nature)
What makes this compound interesting?
Avoid selecting compounds already covered by your classmates and as you respond to at least two of your peers, consider reviewing the response from someone who chose a different compound.

Bleach and Vinegar
Julie and John just moved to a new apartment. Julie is planning to clean the kitchen and wonders if she should use vinegar or bleach. John notes that it may be more effective to use both at the same time and recommends using that solution for cleaning. Julie is suspicious of this idea. She notes that vinegar contains acetic acid (weak acid) and bleach contains sodium hypochlorite (strong oxidizer). She wonders how these compounds will act when combined.
Explore properties of acetic acid and sodium hypochlorite and explain why they are used as cleaning and disinfectant agents.
Identify other acids and oxidizers routinely used for cleaning purposes.
Determine whether Julie should follow the recommendation provided by John. You will need to write an equation for the reaction between acetic acid and sodium hypochlorite. Identify products of the reaction and discuss their safety.
Your paper should be 1-2 pages in length and conform to APA guidelines in the CSU Global Writing Center. Items that should be included, at a minimum, are a title page, an introduction, a body which answers the questions posed in the problem, and a conclusion paragraph that addresses your findings and what you have determined from the data and your analysis. As with all written assignments, you should have in-text citations and a reference page too. Please include any tables of calculations, calculated values, and graphs associated with this problem in the body of your assignment response.  Your reference section should include at least one peer-reviewed, scholarly reference.

The discussion assignment provides a forum for discussing relevant topics for this week based on the course competencies covered.
For this assignment, make sure you post your initial response to the Discussion Area by Week 9, Day 3.
To support your work, use your course and text readings and also use outside sources. As in all assignments, cite your sources in your work and provide references for the citations in APA format.
Start reviewing and responding to the postings of your classmates as early in the week as possible. Respond to at least two of your classmates. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion. Complete your participation for this assignment by Week 9, Day 7.
Discussion Question 1
Using the South University Online Library or the Internet, research the causes of coronary artery disease. On the basis of your research, respond to the following:
State the chemical composition of the sterol present in high levels in most people who belong to the high-risk group.
Distinguish between the ‘good’ and ‘bad’ forms of this sterol.
Explain the function of the good form of this sterol in the body.
List four different foods that are sources of the bad form.
Discussion Question 2
If glucose levels of a patient are high, respond to the following:
State the results that a Benedict’s test would indicate (specify the solution color).
State the composition and the properties of the ketohexose derived from fruit jam.
Describe the manner in which ketohexose acts as a reducing sugar in the test.

Writing Requirements
Minimum of 2 sources cited
APA format for in-text citations and list of references

You have to research thoroughly on different subtopics of this unit by using various books, journals, news clips, articles related to electrochemical cells and corrosion, news clips and other available reliable resources on the internet. This report should be informative, attractive (colorful) and inviting for the reading. You can include mind maps, comic strips, diagrams, “Did you know” sections. Your written text should be elaborated by day to day life examples: charts, graphs, data, chemical reactions, sample examples, where it is applicable. Make it appealing to someone who has not yet studied this unit. The instructions related to this task is given below: 
a) Your report should be typed. It should include one section for each subtopic. b) The sections do not have to be the same length, but all subtopics must be included. c) The maximum number of pages for any one subtopic is three, the minimum number of pages is one. 
d) Please provide in-text citations and a complete list of references in APA 7th edition format. 
e) A summary of unit 5 is attached separately in the module for your convenience.

I need an annotated bibliography with these 3 sources. The topic of my essay is how green chemistry would benefit everyone, and how chemical engineers can play a huge part in it.

Option 1:
Your initial post in the discussion this week consists of two parts. First, choose a molecule used in healthcare, industry, or found in a natural source and discuss the importance of this molecule. Be sure to include at least one outside source and make sure to follow APA citation guidelines.
In the second part of your initial post, we will be practicing naming ionic and covalent compounds as well as polyatomic ions. To begin, give the chemical formula for each of the following: A covalent compound containing no more than two types of elements, an ionic compound no more than two types of elements, and an ionic compound containing a polyatomic. Be sure that these compounds are valid (for example, the charges balance out in the ionic compound) and that the subscripts do not exceed 10.
Option 2:
Your initial post in the discussion this week consists of two parts. First, choose a molecule used in healthcare, industry, or found in a natural source and discuss the importance of this molecule. Be sure to include at least one outside source and make sure to follow APA citation guidelines.
The electron configuration of an atom determines the number of electrons available to participate in bonding with another atom. One method of depicting the valence electrons that an atom has is through the Lewis structure. For the second part of your initial post, pick an element from the periodic table of elements. Identify the valence electrons and the orbitals in which they reside.
Follow-Up Post Instructions
Respond to at least one peer or the instructor. Further the dialogue by providing more information and clarification. Here are some suggestions for how you can add to the discussion and explore the Week 1 content in more detail:
Respond to a peer’s option 1 post and research/discuss one of their chemical compounds. Using the naming rules we learned in class, walk us through each step.
Pick a peer’s option 2 post and answer each of the following questions:
How many unpaired electrons are present?
How many covalent bonds could this element make?
Could this element participate in a double or triple bond? Why or why not?
