Term Paper – at least 2000 word paper (no exceptions and not including citations) on a topic covering a chemical or biology innovation with a focus on the discussion of the course. The student would then be required to research the innovation, the chemistry or biology behind it, and the commercial impact. No papers on Tesla Motors, 3D printers or cell phone/computer “Apps” will be accepted. . Papers must be submitted on D2L by this date or they will be considered late. The marks breakdown for the term paper is as follows: 40 % on the discussion of the science ( no laundry list of what the science does but
how it works.); 40 % on the discussion of the business case and: 20 % on how you put the two together

Submit a draft of the Introduction (Section I) for instructor approval and feedback. Your draft should include all of the following critical elements:
Introduction:
Include your choice of compound and why it was chosen.
Make a connection to your experiences.
Include a preview of what you hope to convey to the reader (this will include showing how the concepts in the class help you understand the information).
What to Submit
Your submission should be about one page in length, with double spacing, 12-point Times New Roman font, one-inch margins, and at least three citations in APA format.
compound is methane.

Before you begin, read the Evaluate Antacids Lab Manual to prepare for the activity.
Gather everything you need for the activity listed in the Materials section before you start.
Check the time estimates in the Time Requirements section. Set aside the time you need to ensure you have enough time to perform the activity.
Perform the activity, following the instructions carefully.
Complete the Evaluate Antacids Lab Report.
Upload the Lab Report when finished.
Submit your assignment here. For details, see the assignment guidelines and rubric. 
Type in all required data and answer responses by replacing the bracketed text with your own content. Images of experimental setups are to be copied and pasted into the
file for submission. Include calculation work with complete units. Save the
file as a DOC file or DOCX file for submission.
All images must
include your handwritten name and date. Lab reports submitted without
experimental images will not be accepted.

Pre-Lab Laboratory Experiment 8 Study the Laboratory Experiment 8 Write-Up Download Laboratory Experiment 8 Write-Up and then do the Laboratory Experiment 8 Pre-LabDownload Laboratory Experiment 8 Pre-Lab for this experiment. All grades are to a large extent (50% for Pre-Labs) based upon your work being thorough, complete and of good quality; you need to be showing me all of the relevant work in getting to the questions answers. Good work includes showing all of the units throughout every calculation. Being too brief is the equivalent of being incomplete. 2) Laboratory Experiment 8 If you have not already done so then study the Laboratory Experiment 8 Write-UpDownload Laboratory Experiment 8 Write-Up and then do the Laboratory Experiment 8 Pre-LabDownload Laboratory Experiment 8 Pre-Lab for this experiment.

To support your work, use your course and text readings and also use outside sources. As in all assignments, cite your sources in your work and provide references for the citations in APA format.
Start reviewing and responding to the postings of your classmates as early in the week as possible. Respond to at least two of your classmates. Participate in the discussion by asking a question, providing a statement of clarification, providing a point of view with a rationale, challenging an aspect of the discussion, or indicating a relationship between two or more lines of reasoning in the discussion. Complete your participation for this assignment by the end of the week.
Discussion Question 1
Using the South University Online Library or the Internet, research acids, bases, and salts that are used in therapeutic processes. On the basis of your research, respond to the following:
Define an acid, base, and salt as they apply to chemistry.
State three examples each of acids, bases, and salts commonly used in therapeutic processes.
From the examples you state, select one acid, one base, and one salt and describe specifically how and where they are used in therapeutic processes.
Discussion Question 2
Using the South University Online Library or the Internet, research buffered aspirin. On the basis of your research, respond to the following:
Define a buffer and explain how a buffer works. [Note: be sure to address the role of conjugate salts.]
Analyze and explain the buffer system in buffered aspirin (carboxylic acid).

For your initial post pick a combination of one of the following molecules, one mass quantity, and one total solution volume from this table. You may not use the same combination as another student so be sure to read any existing peers postings before posting your own.
Molecule Mass Volume
NaCl 2 g 150 ml
CaBr2 6 g 3 L
Li3N 1 g 500 ml
CaO 7 g 14 L
For example, one possible combination would be 2 grams of NaCl in 500 ml of solution. Then, give each of the following for your unique combination being sure to show all of your work:
%mass/volume concentration
Molarity
Osmolarity
Make sure to post at least two high quality posts.

Predict Stability Using Molecular Modeling of Alkenes
Molecular models are a great tool for representing and manipulating the structures and reactions of molecules, and those properties that are dependent on these three dimensional structures. Molecular modelling includes hands-on modeling with physical molecular modeling kits, theoretical, and computational models to mimic the behavior of molecules (Leach, 2009). Molecular modelling is used to study the structure, dynamics, surface properties, and thermodynamics of inorganic, biological, and polymeric systems (Aminpour et al, 2019).
For example, the sis and trans isomerization in cyclic alkenes can be discovered using the results of molecular modeling (Barrows, 2004).
This week you have learned a lot about unimolecular and bimolecular elimination reactions and the stability of alkenes.
Instructions:
Use your molecular modeling kit and build these three alkenes.

Rank the alkenes shown in the ball-and-stick models (A—C) in order of increasing stability.
Take a photo of the models and upload to this assignment.

water volume rises from 28.3 mL to 45.6 mL?
2. A flask that weighs 218.5 g is filled with 125.5 mL of NaCl solution. The total weight of the
flask and NaCl solution is found to be 354.6 g. Calculate the solution density.
3. Three beakers contain different volumes of water of 8.1 cm3, 0.64 L, and 2.7 dL. If all
three volumes were mixed together in a larger container, what would the final volume in
milliliters be?
4. What is the volume of a 0.240-lb sample of ethyl alcohol if its density at the temperature
in question is 0.739 g/mL?
5. The usual dose of amoxicillin for children and babies older than 3 months, who weigh
less than 40 kg, is 20 to 40 milligrams (mg) per kilogram (kg) of body weight per day,
divided and administered every 12 hours. If the drug amoxicillin is 125 mg / 2.5 mL oral
suspension, how many teaspoons in 24 hours should be given to a child who weighs 54
pounds for the maximum dose? (One teaspoon is 5 mL)
