Chemistry

Write a paper (7 -10pages) where you articulate and discuss: 1- What you perceive to be the significance of what you learned in quantitative chemical analysis class and lab. Discuss: – How does it relate to real life and to you personally? – What is the take home message that you learned from this course? -What did you like or dislike (your favorite part)?2- Discuss using references and specific details how the material you learned in class is related to a specific topic such as: -Water and air pollution -Fracking -CO2, greenhouse gas emissions from human activities3- In your opinion, what is the connection between the Animal Farm novella (by George Orwell ) Or Prince by Niccolò Machiavelli and what you learned in class and how is that relevant to your life and future ( that means you need to read the Animal Farm novella or some of Prince by Niccolò Machiavelli)? ( what is the take-home message for both and the connection between the messages)

Why does soap become foam-like when it reacts with water (moisture) or when we touch it with wet hands.. What compound actually causes this physical change? And why does this physical change occur?

-Of the ten disorders, identify the two that you find the most strange and/or interesting and explain your reasons for your response.–Discuss the roles of race, class, gender, SES, and/or ethnicity as they relate to sleep and sleep disorders–e.g., do these areas of diversity affect the experience of sleep and/or the prevalence rates of sleep disorders (feel free to use any of the information presented in Chapter 4 as well as information from your own experiences to support your reaction).

1. Use the ladder operator formalism for harmonic oscillator to derive the selection rule on??? ?|(?? ? ???? ) ?? |??”? for arbitrary n.2. For a heteronuclear diatomic molecule AB, the dipole moment function in the neighborhood ofR=Re is given by??(??) = ?? + ??(?? ? ???? ) + ??(?? ? ???? ) 2 + ??(?? ? ???? )3In which a, b, c and d are constants. Treating this molecule as a harmonic oscillator (using ladderoperator), expand dipole moment in Taylor series around R2 and then calculate the relative intensityof v=0->1, v=0->2 and v=0->3 transitions in terms of these constant and harmonic oscillatorconstants ? and ?.3. (McHale chapter10. Problem7) A general harmonic potential function for water is?? = 12 ???? (???1)2 + 12 ???? (???2)2 + 12 ???? (?????)2 + ?????? ???1???2 + ?????? ?????1??? + ?????? ?????2???The last three terms contain off-diagonal force constants, while the first three are diagonal. Inmatrix form, this can be expressed as 2V=RTFR, where R=(???1 ???2 ???) is the vector whoseelements are the internal coordinates. Find the symmetry coordinates S1, S2 and S3 for water,and the diagonal force constant f which permits the potential energy in form written STfS4. For raman spectroscopy, show that the following equation leads to a symmetric tensor, ?????? =??????, in the limit ??0 ? ?????? .(?????? )???? = 1? ?[???|????|??????|???? |?????0 + ?????? + ????? ????|???? |??????|????|?????0 ? ?????? ? ????? ]

Communication skills are of paramount importance in defining success in your career. Putting your communication skills to good use requires sound judgment in deciding when to speak, what to say, to whom, and for what cause. Thorough planning and preparation are essential for delivering an effective speech and presentation.Give a 25-minute lesson teaching with a PowerPoint (10-15 slides) on one of the following topics:Please pick a topic you are strong in1. GPCR signaling2. Ion channels and neuronal communication3. Receptor tyrosine kinases and cancer4. Cell cycle regulation in the cellThe lesson presentation should include a title and reference slide and have between 10-15 content slides. At least four references should be cited (only one can be the textbook).While APA style is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center.

Discuss the analytical procedures for analyzing soaps and detergents

Calculate the density of each of the substances described below: (3 points each, 9 points total)a. a salt water solution with a volume of 25 mL and a mass of 26.2 g:b. a block of wood with a mass of 35.5 g and a volume of 15.6 mL:c. a container filled with gas. The mass of the gas is 7.65 g and the volume is 12.5 mL.

For this topic, you will select two problems from the Chemistry: Atoms First, OpenStax text (in the link there is a book), one problem from each of the following two problem sets:For Problem 1: You MUST select a problem from the end of the chapter “Exercises” from Chapter 3: Problems 1-15; 46-86.For Problem 2: You MUST select a problem from the end of the chapter “Exercises” from Chapter 14: Problems 1-25.These problems and their discussions will be included together in one post. After you decide which problems you would like to discuss, start a thread in the Topic Discussion. You need not fill in the content—only begin a thread with a subject line that includes your name and the problems you will be discussing. When you are ready to fill in the details of the post, you can simply go back into your post and select “Edit” and put the information into your post. By starting your post, you are claiming your problems and no other student is allowed to choose the same problems.You need to:*show work to find solution (you can use an embedded image or the ? button on the Rich Text Editor if appropriate).*explain in the text how you approached and worked through the problem.Ideally, you will choose problems that you had a hard time solving until something is selected (which you would then explain–what you figured out that you did wrong, etc.). Either way, you should lead a discussion about the problem. This will help everyone go through the thought process of these problems, see different ways that students set them up, compare approaches, maybe learn new strategies and hints, recognize mistakes, etc. If you cannot solve the problem at first, no worries, your classmates and myself will give you help you along and you can edit your problem until it is due. If you are having trouble, show your work and explain where you are getting stuck. Remember, you are not getting graded on whether you solve the problems correctly, but rather the attempt you make and the discussion you have with us related to it. So it will likely be more beneficial to you to select challenging problems with which you need help as opposed to easy ones that you can already solve.
