Chemistry

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.

please choose one topic for the article from the followings: 1. What is fatty Liver and how to prevent and reverse this disease? 2. What is Kidney disease and how to prevent and cure the disease? Writing Procedure:   -First do a research for the topic in the scientific journals such as Pubmed/NCBI/NIH or others online resources.   -Select at least 10 published journals for the topic, review and summarize the content in your article   -The article should be well explained with necessary image in every paragraph. Images should be collected from the article or from the free image sources so that it does not fall under copyright law.    -Each paragraph should have bolded heading and every item in the paragraph should be also sectioned out with bolded heading.     -There is no limit for the length of the article, but it has to be minimum 550words, and it MUST be in 10  FONT SIZE.    -References have to be cited twice- inside the content using only order number as well as at the end of your article in order using MLA format.. Article will not be accepted if scientific references are not cited properly!

You perhaps have gone through several electronic devices in your life, for example, cell phones, tablets, and/or computers.  How did you dispose of these devices when they outlived their usefulness?  Your paper should clearly reflect your views, how they have changed over time, and whether you are thinking of doing anything differently. You should use and reference at least three outside resources to justify your views.

You are required to write an essay on the topic “Chemistry in Health-Care climate change and Environmental Protection. To format of the essay is the following atleast 6 pages written in times new roman or arial fonts with size 12 font and single spaced. You are encouraged to add relevant figures in your essay write up and add the reference’s used.

HI hope you’re well :D. My friend has this assignment. Even though it is chemistry it does not need to have the technical vocabulary. More of the pro and cons of Chemotherapy. TWhat are the pros and cons about people receiving Chemotherapy and Radiation if that person has stomach cancer? And how do chemotherapy and radiation work on cancer patients?Please  ensure you have at least 2 professional references and that they are properly cited in APA format.  Report length should be at least 500 words.

.” In this essay please do the following: 1) Define what science and chemistry are to you 2) How has your view on the importance of science and chemistry changed? (If it has not, you can just say that) 3) Based on what you have learned in class, how are they involved in your life? How could they apply to your future career? 4) What would be your response to a friend who says that taking chemistry/science is pointless? 5)

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.

Do you know the reason ice floats in your drink? It is because the density of ice is lower than that of water. Chemistry is happening all around you at all times (both physical and chemical changes). What have you observed within the last week that involves chemistry? What is that process/reaction?

Where in your everyday life do you come across any part of the electromagnetic spectrum? (Chapter 4 in the textbook.)Give one example, and state which part of the spectrum you example is in.i only need 2-3 sentences not a WHOLE pageand also im not paying over 10 dollars just for 3 sentences

Discuss symptoms of the use of each drug. Your response should be at least 275 words in length.       QUESTION 2 Identify the six toxicological principles that are applied in evaluating a poisoned individual. Give an example of two of these principles. Your response should be at least 275 words in length.       QUESTION 3 How can toxicant absorption be reduced after exposure to the skin? How can absorption be reduced for orally consumed chemicals? Your response should be at least 275 words in length.     QUESTION 4 “G” is the street name of the commonly abused street drug GHB.
