[SOLVED] A Chemical Reaction

Predicting Products of a Chemical ReactionWrite the type of reaction on the line: combustion, synthesis, decomposition, single replacement ordouble replacement. Then, predict the products of each reaction. You may need to refer to the activityseries, solubility charts or periodic table. If the reaction would not occur, write “NR” on the product sideof the equation. Finally, balance the equation with the smallest integers (whole numbers) possible.1. ____ Al2O3 ?2. ____ Fe + ____ S ?3. ____ KClO3 ??? ?4. ____ Sn + ____ HCl ?5. ____ C2H5OH + ____ O2 ?6. ____ Na2SO4 + ____ BaCl2 ?7. ____ KF + ____ Br2 ?8. ____ Ca(OH)2 ??? ?9. ____ C6H6 + ____ O2 ?10. ____ NaOH + ____ HNO3 ?11. ____ Cu + ____ AgNO3 ?12. ____ KI + ____ NaNO3 ?13. ____ Sr + ____ N2 ?14. ____ HgO ??? ?15. ____ C4H10 + ____ O2 ?16. ____ Na + ____ HOH ?17. ____ Pb(NO3)2 + ____ K2CrO4 ?18. ____ Fe + ____ CuCl2 ?19. ____ H2 + ____ N2 ?20. ____ NaOH + ____ H2SO4 ?

[SOLVED] Molecular Spectroscopy

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 ? ?????? ? ????? ]

[SOLVED] Quantitative Chemical Analysis

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)

[SOLVED] Sustainability and Resilience

1. Supply a url/link to a news article (within the last year or so… 2019-2020) that discusses a global change issue that is important to you. In the prompt explain why this issue is important to you (provide a few sentences).2. Think about a particular application of remote sensing that you think is important. Do an internet search to find an example image being used to address this application. Upload a copy of that image and discuss briefly the application, why it is important, and what limitations you see in how remote sensing can address this application.3. Professor Meerow discussed differences between Sustainability and Resilience. Two such differences were the concepts of “fail-safe” vs. “safe-to-fail” and “maximizing efficiency” vs. “maximizing adaptive capacity”. Can you think of one specific example from your everyday experiences with the design/operation of your city that illustrates these differences? Provide either documentation of a catastrophic failure or a well-designed adoption which established Sustainability and Resilience. Provide links if necessary.4. Different cities and countries are vulnerable to climate change for one reason or another. Find an example, other than those used in the learning materials within this module, and comment on the vulnerability of that location to climate change using the vulnerability framework we’ve introduced. Give us your thoughts on WHY they are vulnerable and also on any solutions (mitigation/adaptation) that might be appropriate for that particular community. Respond with a short paragraph and links if necessary.5. Geoengineering: find a fictional movie/television series which uses a form of geoengineering (for better or worse) as a primary plot component. Provide the name of the media and briefly discuss what geoengineering methods are used and how effective they were.6. You’ve learned about a lot of potential approaches to address climate change–diet, population control, geoengineering, renewable energy, nuclear energy, etc. Flex your creativity and out-of-the-box thinking… what is one potential technology (rarely mentioned) that you think could be developed/deployed to address global change issues? Provide a short paragraph and links to support your argument!
