answer the questions below

Please show your calculations for obtaining your percent yield. Include the calculations for the theoretical yield as well. Also, if something went wrong during the course of your experiment (i.e you spilled your product, did the work-up wrong, etc.) you can explain about it here.
(weight of empty vial is 16.65g and the weight of vial product is 20.84g) something went wrong during the experiment but I don’r know what you can predict what happed and explain it but one thing I’m sure of is that I used a used stir bar.
2. Analyze your NMR spectra using Mestrenova and upload a picture of it on this assignment. In your spectra, you should have the chemical shifts of each peak, and the integration underneath it as well. You also have to include an explanation matching up the peaks in your NMR spectra to that of the product, methyl benzoate. Explain why you think you matched up the peaks properly based on chemical shift, integration, and splitting pattern. If you have extra peaks in your NMR that do not match up to any proton peaks in your product, explain where they could have come from.

Vaccine case study

Epidemiology – Who is at risk for developing this disease? Describe mode of transmission, historical and present incidence, prevalence and mortality.
Etiology and Pathology – Describe classic signs and symptoms, and course of disease.
Prevention and Treatment – Explain how the disease is prevented. What is the typical treatment? Side effects of treatment?
Laboratory Diagnosis – What are the laboratory assays that are utilized in the diagnosis of this disease? How reliable are they? What is the likelihood of a misdiagnosis?
Vaccine – What is the vaccine like (type of vaccine)? What are its cost, risks, and benefits? Why are the “anti-vaxxers” opposed to use of the vaccine? Does the benefit of vaccinating outweigh potential risks? Should medical practitioners promote vaccination? Should it be mandatory for society? Be sure to include charts, graphs, photographs and specific data to tell your story and make your case.
Citations – Minimum of four peer-reviewed resources (Textbook, journals, CDC, WHO, etc.). It might also be useful to review websites that are not peer reviewed to find information about biases to vaccination.

Lab Report: Identification of an Unknown Acid

Define titration. What is the purpose of a titration experiment?

What is a primary standard? What was the primary standard in this experiment? (If you didn’t use a primary standard, indicate what it should have been)
Why were there 2 standard solutions? That is, why wasn’t NaOH(aq) used as a primary standard for titrating the unknown acid? (If you didn’t use a primary standard, then explain why NaOH(aq) probably should not be used as a primary standard.)
How would melting of a pure sample differ from melting of an impure sample?
What is Ka? What is pKa? What does a high Ka mean? What does a high pKa mean?
What is a buffer?
For a weak acid, under what conditions will pH = pKa?
Procedure ReferenceWhat changes were made to the published procedures?

Results and CalculationsUse the results that were provided to you and clearly indicate your unknown number.Create (don’t copy the Excel tables) a table summarizing your major experimental data (i.e. gram molar mass, melting point, and pKa of monoprotic unknown acid).
Show sample calculations.

Make a second summary table that shows the theoretical values for your top 2 or 3 best guesses for the unknown acid’s identity. This table should include the theoretical gram molar mass, melting point, and pKa of these guesses with percent error values.

DiscussionState the identity of your unknown monoprotic acid from a list of possibilities (Links to an external site.) by usingRemember to be quantitative, whenever possible.
Discuss how you came to that conclusion using your average gram molar mass with standard deviation and average melting point range and pKa to justify your identification.
Explain how you narrowed down the suspects and state your second choice and/or third choice, if appropriate and how they were eliminated.
Be sure the discussion includes, how many standard deviations the actual molar mass of the acid you believe best represents your unknown is away from the experimental molecular mass of the acid.
Also, does the actual melting point of your identified acid fall within the range of your experimental average melting points? Explain why or why not.
Discuss the accuracy and precision of your average gram molar mass and melting point. (How do you quantify accuracy? How do you quantify precision?)

Discuss any sources of error that may have occurred in the experiment. For example, if you added too much base to one of your titrations, you should identify how that would have affected your gram molar mass calculation. Would it increase or decrease?

ConclusionEvaluate the objective of the experiment and restate the identity of your unknown acid, the average gram molar mass, the average melting point range, and the average pKa.

Post Lab Questions

A response for the follwoing

An example of a genetic disease is Spinal Muscular Atrophy (SMA). This disease meets the requirements because when tested for it, it is found that “gene alterations (mutations) in the SMN1 and VAPB genes cause SMA” (n.a., 2012)————————————————————————————————————————-
2-What classifies a disease as a genetic disease?
A genetic disease is caused by an abnormality in someone’s genetic data. The abnormality could be a mutation of a gene or a missing/extra chromosome. A genetic disease is most often an inherited but can also be acquired through mutation.
Provide an example of a genetic disease and explain how it meets the requirements to be labeled a genetic disease.
Huntington’s Diseases is a disease that is caused by the mutation of Chromosome 4. This defect causes the production of huntingtin protein to be defected. The disease is hereditary and causes neurons to die. The symptoms are uncontrolled movements, abnormal body postures, changes in behavior, slurred speech, and difficulty eating and swallowing (Huntington’s Disease Information Page, n.d.).
There is no treatment for this disease at this time.

Organic chemistry e×am

the e×am is 1 hour long. Our instructor allows us to see the previous year’s e×am so I have attached the answer key to that. Expect the e×am to cover the same topics and be the same length or possibly shorter. Once the e×am begins, I will send you the file and I will need the answers sent back an hour after I send it to you. It is best if you print out the entire e×am and write on it, then send back a PDF scan of the answers. My submission must be exactly as long as the e×am and the questions must be answered on the pages that they were assigned. If you prefer to answer the questions on a blank sheet of paper rather than printing it, the questions must be answered on their respective pages. For example, if question 4 was given on page 6, then on the 6th page of the submission, question 4 must be present. a cover page must also be included, similar to the first page of this attachment. This headache can be avoided if you just print the e×am and write directly on it. IF YOU ARE NOT FAMILIAR WITH ANY OF THE TOPICS IN THE ATTACHMENT, THEN DO NOT ACCEPT THIS QUESTION. thank you.
