Visit the DHMO website (http://www.dhmo.org/ (Links to an external site.)) and review the materials about the fact and dangers of dihydrogen monoxide.  Read the first page of the website and then on the left side review each of the following tabs:
 Dihydrogen Monoxide FAQ
 Enviro Impact of DHMO
 DHMO and Cancer
 DHMO Research
 DHMO in the Dairy Industry
 MSDS for DHMO
 DHMO Conspiracy
 Editorial: Truth about DHMO
Post a response thread about how the sharing of chemical information can be misleading. 
I am looking for 100 plus words.  Discuss and describe your opinion of this website, the day-to-day use of DMHO, and the importance of basic chemical literacy in our lives.  You will need to use some of the chemical naming that we have covered in the notes and videos to truly understand the meaning and identity of some substances in the DMHO website.

Finally, list one additional ionic compound.

Please complete the following steps for your discussion post and response.
Look around your house for an ionic compound. 
Look around your work (or the internet) for an ionic compound in the medical field.
Discuss each ionic compound, including the name and formula, and how it is used at home and in the medical field.
Make sure to discuss how the cation and anion were formed.
Finally, list one additional ionic compound. Don’t name the compound, just list its molecular formula.
Please be sure to validate your opinions and ideas with citations and references in APA format

DSM 5 tr summaries     Summary Set 2, due at the end of Module 3 (total of 3 sum

DSM 5 tr summaries 
  
Summary Set 2, due at the end of Module 3 (total of 3 summaries; 1 page per category=3 pages of content):
• Substance-related and Addictive Disorders
• Trauma and Stressor Related Disorders
• Obsessive-compulsive and Related Disorders
Overview – a brief overview of the general category. In one or two sentences, identify the 
characteristic(s) that all the disorders in the category share. (Example: in the Depressive 
disorders, all the disorders are characterized by feelings of sadness.) 
Disorders – For each disorder in the category, write one or two sentences that provide a brief 
description of the disorder. In the Overview, you noticed what is similar across the disorders in 
the category: in the Disorders section, you will identify the main feature of each disorder that 
distinguishes it from the rest of the category (e.g., time frames, severity, types of symptoms, etc.)
Risk and Prognostic Factors – Choose one disorder from each category and provide a brief 
summary of the risk and prognostic factors as found in the DSM-5-TR. 
You will organize each summary by using the current edition of APA headings. Start each 
summary with the category title using a Level 1 APA heading. Overview, Disorders and Risk 
and Prognostic Factors should be Level 2 headings. 
You will include an APA title page and reference page. An abstract is not needed. Remember, 
the graduate program at Liberty uses the guidelines for “Professional” papers, not the “Student” 
version.
As this is primarily a summary of the DSM, you may start your DSM-5-TR Summaries 
Assignment paper with the statement “All of the following information was taken from the 
Diagnostic and Statistical Manual 5th Edition (American Psychiatric Association, 2013) unless 
otherwise noted.” When including this statement, you do not need to use in-text citations for the 
DSM-5-TR. Using other sources is not recommended; however, if you use additional sources, 
you will need to cite and reference them.

1. The text of the paper must be at least 4 pages in length.
One page must contain a hand-drawn molecular structure in ink showing hybridizations and bond angles, with a list of chemical and physical properties. The last page must be a bibliography, clearly showing the references used for the paper.  Make sure journal articles are cited properly, including journal title, year, volume, number, author, article title and pages. Total length of the paper should be 4-5 pages, so that leaves 2-3 pages of actual writing.
2. Format the paper using 1-inch margins, double spacing and Times Roman 12-point font.
3. A minimum of Four (4) references is required.  Onereference must be The Merck Index, the best place to find the chemical/physical properties and a structure.
           The Merck Index link:
 https://library.shoreline.edu/MerckIndex   
 You need to log in with your Shoreline username and password to get access
4.  One must be a peer-reviewed scientific journal about your molecule from Shoreline  
database.
Two magazine articles websites (for example: the Encyclopedia of Science and   
 Technology) are a good source for current applications and information. No more than  
two websites may be used, and they must be crediblewebsites, i.e., .edu, .gov.  Wikipedia 
does not count as an acceptable reference, but it is 
 a good starting point.
​​
5.​Include the following information on your molecule, as appropriate.  Not all information will be available for all molecules, but something in each section must be present.
a.​Background: discoverer, date discovered, origin of name, source, first known use,history, developing company, etc.  
b.​Major uses or industrial importance – keep to two or three uses, how it works or achieves desired effect if applicable.
c.​Anything else of interest – here is where any unusual/unexpected uses, side effects,applications or issues discovered during your research should be presented.  This is the fun part!
​d.    ​Include on a separate page: hand-drawn structure showing hybridization and bond angles, physical and chemical properties including toxicity (if any).
6.​Treat this as an English composition.  Use complete sentences and coherent paragraphs.  Although I am not an English teacher, I will consider spelling and grammar in the grade.  It is a very good idea to make use of the Reading/Writing Center and the grammar/spell check function in Word.
7.​The paper is worth 10% of your total grade.
