  • 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.
