Chemistry

Discussion 1: Discuss how the “law of conservation of mass” is applied in chemistry in terms of balancing of chemical equations.Discussion 2: When balancing chemical equations, which one do we adjust: “stoichiometry coefficients “(numbers in front of the formulas) or “subscripts” (numbers in the formulas)? Give relevant examples to support your discussion answer.Discussion 3: Discuss the connection between : “Avogadro’s number and the Mole”.Discussion 4: Discuss how the three types of chemical reactions discussed in chapter 3 are different in terms of the products formed. (Note: Use equations to support your response).Discussion 5: Which reactant controls the theoretical yield in a chemical reaction: THE LIMITING REACTANT OR THE EXCESS REACTANT? Discuss in detail using relevant examples.

Compose a minimum 1-page essay summarizing the article “Clearing the Air”Preview the document from the April 2020 issue of ChemMatters by focusing on the questions below. Be sure to proofread and edit your paper for clarity and review the grading rubric to ensure you include all of the required elements in your summary. Find the reading rubric at the bottom of this page.Focus Questions:How can ozone help and hurt life on Earth? What makes the same chemical have both effects?The current coronavirus pandemic began in December of 2019.  The amount of cases began to increase dramatically worldwide in March of 2020. The virus is particularly dangerous to those with respiratory issues.  Based on the info in this article, what additional dangers may be present for people fighting the coronavirus in urban areas as summer approaches again in the northern hemisphere?Observe the map of the United States titled “8-Hour Ozone Nonattainment Areas (Jan. 2020)” on page 11.  Dangerous levels of ozone can be found predominantly in areas with a high population density.  Create an argument based on evidence as to why California contains the greatest amount of land area with extreme levels of ground level ozone.  There are many areas in the United States with high population density such as the Northeast U.S.  What factor or factors may be causing the increased levels in California?Hint: find other maps of the US to compare to. Think about all of the factors mentioned in the article. Make sure to cite, and include any maps you used at the very end of your paper.In what format should I write my article?11 pt. Calibri, Palatino, or Times New Roman; single-spaced; normal margins.In what format should I cite?All in-text and Works Cited should be in MLA, 8th Edition.What should the Title be?it should be “4th Six Weeks’ Reading Summary: Clearing the Air”

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.

The essay should focus on how alcohol is metabolized in the human body and how it deteriorates or affects the brain and liver. Some alcohol-related diseases in the brain or liver should be discussed.

1. How are covalent bonds similar and different from ionic bonds? What types of atoms are involved in each type of bond? 2. Determine whether the following bonds are nonpolar covalent, polar covalent, or ionic. If the bond is covalent, is the bond a single, double or triple bond? Also if the bond is polar covalent, determine polarity -which atom is slightly positive and which is slightly negative in charge? a) O2 b) NaF c) CO d) NH3 3. Use the systematic approach to covalent bonds (coordinate covalent bonding) for the polyatomic ion SO32- what type of bonds are between the sulfur (central atom) and each of the oxygens? 4. What is the geometry, name, and overall polarity of the molecule? a) NCl3 b) CO2 c) CF4 d) BH3

Findings for a stroke and how it affects the lives of patients and their families

What is the difference between “natural” and “non-natural” medicine, supplements, or products? Based on what we’re learning this semester, how rigorous is that distinction? Especially in our consumer age when the “organic” label comes with commercial overtones, it’s important to think about what’s behind the label. Using examples, and incorporating information from class, answer one of the following questions: Make an argument for or against the use of “natural” or “organic” products in a particular area of life (e.g. health, medicine, cleaning, clothing, etc.) Make an argument for how to define a product as being “natural” or “organic”. Content: You should be sure to address the concepts necessary for understanding the explanation to your answer, explain the concepts, layout your answer to the question, and illustrate your answer with informative examples (plural). You may draw your examples from any field of chemistry or medicine you like, and it is recommended that you use this project to highlight the relevance of chemistry to your chosen field of study and/or professional discipline of interest. Format: You should prepare a multimedia presentation (be creative!) to explain the ideas in your presentation (PowerPoint, video, skit, song, etc).
