HAzardous materials

All ammonium compounds, which contain an ammonium ion (NH4+) and a negative ion, are thermally unstable.

A. Discuss two ways that ammonium compounds decompose when they are heated. What chemical reaction is involved in the thermal decomposition of ammonium persulfate?

B. What is the most likely reason OSHA requires ammonium nitrate to be segregated for sulfur or finely divided metals? Explain your answer.

C. What is the most likely reason OSHA requires employers to protect flooring and handling areas in buildings against impregnation by ammonium nitrate and requires that the floors be constructed without open drains, traps, tunnels or pits into which molten ammonium nitrate could flow and be confined in the event of a fire?

Need this week 4 discussion done by 26

 

In recent years, high fructose corn syrup (HFCS) has been blamed for the increased prevalence of overweight and obesity in the U.S. (Bray, Nielsen, & Poplin, 2004). It is present in many foods, including those we would expect to find it in, such as candy, to those unexpected, including salad dressing.

If your last name starts with the letters A-L you are assigned the “pro” side. If your last name starts with the letters M-Z, you are assigned the “con” side. The “pro” side will make a case that HFCS has contributed to the increased body weight of Americans. The “con” side will make a case that HFCS has not contributed to the increased body weight of Americans. Consider why Americans may or may not choose foods with HFCS, including cost, effect on nutritional status, and what other nutrients may be provided in foods that typically contain HFCS.

You must back up your argument with reputable references, which includes scientific journal articles that can be accessed through the South University Online library. Remember that we are discussing this topic to learn from one another’s research and that the side that someone may be defending may not be what they truly believe; please be kind and considerate in your posts. Reference:

Bray, G., Nielsen, S., & Popkin, B. (2004). Consumption of high-fructose corn syrup
          in beverages may play a role in the epidemic of obesity. American Journal of
          Clinical Nutrition, 79(4), 537-543.

Chemistry of Hazardous Materials 1

We come in contact with toxic substances every day. After reviewing the material in this unit, share with the class what you think are the two or three potentially most toxic substances that can enter our everyday lives.

Do you think that the Occupational Safety and Health Administration (OSHA), the Environmental Protection Agency (EPA), the Consumer Product Safety Commission (CPSC), and/or businesses are doing enough to limit these potential exposures? Why, or why not?

Please understand that Fluoride and Formaldehyde cannot be used as examples here. That is due to the vast amount of bad, talking-head science that exists around these materials. If you chose to write on these two materials, you must include a full APA reference for a peer reviewed journal article to support your argument.

 

No word minumum but must answer the entire question
