  • 5-2 Final Project Milestone Two

    Using the Final Project Rubric as a guide, create the body of your final project. Include the introduction (updated from Milestone One feedback), (ATTACHED PDF) as well as the next three sections of your project (II. Compound Description, III. Reaction Description, IV. Class Connection). If there are sections that you anticipate completing based on week six or seven material, you should clearly indicate this along with a brief description of the information you anticipate including. You will submit a draft of the Compound Description (Section II), Reaction Description (Section III), and Class Connection (Section IV) of the following critical elements. * Compound Description: In this section, describe the compound you have chosen. You must include the following information: * Physical descriptionState of the compound and identifying characteristics. * Molecular descriptionProvide molecular weight, constituent elements, types of bonding, and polarity. * Properties descriptionProvide relevant properties such as solubility, density, state, and boiling/melting point. * UsageDescribe the usage including relevant energy flows. * Economic importanceInclude at least three years of recent information on the production and cost of the compound and indicate any trends. * Reaction Description: In this section, you will describe a reaction related to the production or use of the compound you have chosen. You must include the following: * Type of reactionDescribe the general class of reaction (combustion, acid/base, redox, etc.). * Heat of reactionProvide the amount of heat that must be added or removed from this reaction at the relevant temperature and whether this reaction is exothermic or endothermic. * All products, reactants, and catalystsInclude a balanced equation with all states of participants. * Special considerationsDocument the safe operating range of this reaction, safety considerations, and side reactions that may produce unwanted products. * Summary of other possible reactionsProvide either another reaction to produce the compound or an alternate use and its reaction. * Class Connection: Using some of the ideas from the class resources and textbook, make quantitative/qualitative comparisons of the compound and/or the related reaction described earlier. These comparisons can be to different compounds/reactions or to the same compound/reaction at a different condition. Include references to the specific class week/resource or textbook section/chapter as appropriate. The following comparisons must be included: * Difference in stateHow does the compounds use change in a different physical state or when mixed with other compounds at different concentrations? * Difference in the reactivity of the compound with the reactivity of a similar compoundDoes more or less reactivity change the way in which it is used? * Change in the heat of reactionDiscuss the effects of changing the reaction temperature; for example, would the change make it unsafe, too slow, unstable, etc.? * Difference in the molecular weight of this compound compared to similar compoundsHow does this difference affect properties (e.g., solubility) to change the range of uses? What to Submit The draft should follow these formatting guidelines: 4 pages (3 pages if tables and figures are omitted), double spacing, 12-point Times New Roman font, one-inch margins, and at least three citations in APA format.

  • Module 1 Lab Report

    I have attached the procedure/reading associated with the lab. I am attaching each section needed and within is exactly what each section must talk about/refer to. Must meet all requirements listed in each section.

    INTRODUCTION:

    Does the introduction contain the following?

    • A one or two sentence description of the procedure
    • The goal of or reason for the procedure and how success in reaching this goal will be determined
    • Physical or chemical properties being exploited to transform the compound by reaction and collect and isolate the final product
    • A brief discussion of how the 12 Principles of Green Chemistry were considered in the design of this procedure.
    • A proposed mechanism for this reaction
    • A mention of specialized equipment used to complete the procedure and confirm your predictions (Hot plates are not special equipment)

    DETAILS AND OBSERVATIONS:

    Does the observations section contain the following?

    • A succinct and objective report of how the procedure was done in the lab written in paragraph form using past tense.
    • Enough information that your teaching assistant could reproduce your work and achieve similar results
    • Any time these instructions tell you to observe or record your observations, you should have a written observation describing what you saw ( tells you when to observe or record observation in the reading and what I observed is included below ) ( If it tells you to include the observation past part 3 because I didnt get that far just say what you should have observed if it was completed)
    • Your pre-lab plan is already turned in. If your Details and Observations section looks too much like your pre-lab plan, then points will be deducted. Report the unique details (included below) of your experiment and anytime you deviated from the pre-lab plan.

    *I have attached the pre-lab plan to ensure that this section does not look too much like it**

    UNIQUE DETAILS:

    • Part 1 – 6 drops of cyclohexanol = 0.160g, not 0.145g
    • Part 1 – 4 drops of acetic acid
    • Part 1 – pH<7, so added 3 more drops of acetic acid = pH of 2
    • Part 1 – measured 2.5 mL of 6% sodium hypochlorite instead of 2.0.
    • Part 1 – Observation after 6% sodium hypochlorite flask got warmer
    • Oxidant check – When testing for oxidant present, this is what happened. Negative on first test. Added 5 more drops of hypochlorite solution, 5 more minutes in water, another negative test, added 0.5mL hypochlorite (10 drops), 5 more minutes in water, another negative test. added another 0.5mL hypochlorite (10 drops), 5 more minutes in water, another negative test, added 3 more drops, 3 more minutes in water, received a barely positive test (positive color on the rim/outline of the drop). Once positive it took 40 drops of bisulfite to get a negative test.
    • Oxidant check – 1 drop of thymol blue indictator = turned solution blue automatically without 6M NaOH. added 2 drops of 6M NaOH just for safe measure.
    • Part 2 – Temperature range during collection = 85 degree – 95 degree
    • Part 3 – Added 0.104g or sodium chloride
    • Part 3 – The pre-weighed Erlenmeyer flask weighed 17.096g.
    • Part 3 – was able to extract with diethyl ether all 3 times, but lab ended before I could measure the mass of flask + product.

    **EVERYTHING PAST THIS POINT IS ANOTHER STUDENT IN THE LAB’S RESULTS**NOT MY RESULTS**SPECIFY THAT THIS IS ANOTHER STUDENTS RESULTS**

    • Part 3 – Another student’s pre-weighed Erlenmeyer flask weighed 16.7g and the flask + product weighed 17.3g
    • Part 4 – Meltemp was set at 149 degree celcius
    • Part 4 – Started to melt at 137 degree celcius and stopped at 149 degree celcius

    CONCLUSION AND DISCUSSION :

    Does the conclusions section contain the following based on your details, observations, and results?

    • An answer to the claims and predictions you made in the introduction
    • Discussion and comparison of the amount of hydroxide solution to acetic acid. Was the acid regenerated like a catalyst or did it seem to be consumed?
    • A suggestion of what other specific alcohol(s) would you suggest be appropriate for oxidation to ketones with this procedure?
    • Comparison of the melting point of the hydrazone derivative with the expected literature value and an evaluation of its purity
    • Evaluation of how well this procedure adopted the 12 Principles of Green Chemistry
    • Are all your conclusions based on the data you have collected? If you need or want to refer to another source, please include where that data can be found.
    • Suggestions for future research that would add support for your prediction or further examine the physical and chemical properties exploited in this procedure

    Discuss 2 of the following:

    • Given access to an IR spectrophotometer, what specific additional information would you collect to support the claim that cyclohexanol was or was not oxidized by your procedure?
    • Given access to an H-NMR spectrophotometer, what specific additional information would you collect to support the claim that cyclohexanol was or was not oxidized by your procedure?
    • In the event that some cyclohexanol was oxidized beyond cyclohexanone and was completely oxidized to adipic acid, suggest a simple way to extract the acid from the desired product.

  • Kinetics Lab Report

    • Your draft and final full lab report are to be based on one of the ALEKS experiments you conducted. You are to use the exact data, graphs, tables, etc. that you prepared in ALEKS and compose a report on that exact experiment. You can research how the concept explored in the experiment can be used in other areas (this is good information that could be part of your introduction), but you do not need to develop a new lab experiment.
    • ALEKS provides you a brief introduction to the concept and the procedure/materials, but now you need to interpret your results. The Results and Discussion sections of the report are the most important sections of any lab report. You need to discuss the meaning of your results (compare and contrast it with the accepted value for a constant, as an example) and provide an error analysis – what are the one or two major sources of experimental error that could have affected your result. For example, if your value is higher than the accepted or true value, what could lead to a higher than expected value. If your value is lower than expected, what could have caused a lower value. Specific values and details are needed here, rather than general statements.
    • In your final report, the materials should not be a bulleted list, but rather, your materials should be introduced in full sentences. In addition, the procedure should also be in sentence/paragraph form, rather than a list of steps.
    • References will also be needed! (Textbook is attached)
    • *Please carefully follow the lab report guide as you prepare your draft.*
