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 comp...

Option 1: We will begin this topic by practicing the use of the scientific method. The steps of the scientific method are: observation, hypothesis, experiment, results, and theory. Using your understanding of the scientific method from your readings and lessons, you will be applying this knowledge to a real world situation. Take a real world scenario in the news, or another outside source and apply the scientific method, being sure to detail the controls on your experiment. Describe a result th...

Option 1: While we often think of radiation as dangerous, radioactive isotopes are widely used in the field of healthcare as well as in many other fields. For your initial post, choose a radioactive isotope used in healthcare or another field and report on how your isotope is used. Be sure to answer both of the following questions as part of your initial post: a. What type(s) of radioactive decay does your isotope undergo? b. How is your isotope used? Use at least one outside source and ci...

Week 4 Discussion: Chemistry in the World Around Us Initial Post Instructions While we often do not realize it, acidic and basic solutions are a part of our daily lives. Pick a solution in your home, work, or even outside (be sure to check the label to make sure that whatever you are measuring is nonhazardous and water based). Some possible solutions are shampoos, beverages, still water in your backyard, contact solution, etc. Research a compound or compounds found in your chosen solution, c...

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...

Initial Post Instructions For your initial post pick a combination of one of the following molecules, one mass quantity, and one total solution volume from this table. You may not use the same combination as another student so be sure to read any existing peers postings before posting your own.

Option 2: (Selected) Choose a scientific paper written in the last year. The Chamberlain library is a great source for this. For your chosen paper, look into the study and discuss how the scientific method was used in this paper. Be sure to note they hypothesis, variables, results, etc. Based on your understanding of the scientific method, be sure to discuss if you find this paper as a trustworthy source and why.

Option 1: Complete Solution We will begin this topic by practicing the use of the scientific method. The steps of the scientific method are: observation, hypothesis, experiment, results, and theory. Using your understanding of the scientific method from your readings and lessons, you will be applying this knowledge to a real world situation. Take a real world scenario in the news, or another outside source and apply the scientific method, being sure to detail the controls on your experiment. De...
