Thermochemistry Enthalpy and entroypy of a spontaneous process

Paper details Take a moment to formulate and write down a hypothesis describing the criteria of spontaneous reaction.

I have attached the lab results. Please look at the file, its not just the lab procedure. The pre-lab questions should be answered at the beginning of the report then at the end of the file its more information on what is needed in the report.


Paper details 1. answers the questions in the file (questions to answer) using the data and video link provided
2.On notebook paper (or electronically) record your data and observations from the lab. Take a picture and submit here.
3.Also, answer the following questions in the Lab Manual – Separation of a Three-Component Mixture by Solvent Extraction
Part 3: Questions 2, 3, and 4 (p 45-47) [Provided in files labeled question 2,3,4]

Isotopes in Cancer Treatment

Paper details Instructions:
Students will work in groups of 2-3 students. Working as a group, students will pick a topic based on course outcomes (COs), research that topic for its connection to nursing/health care. Students may pick a topic from the suggested topics list or instructors may choose to assign specific topics to students. Additionally, students may choose a different topic that is relevant to the COs as long as the faculty approves it. Students must get approval for their chosen topic and format from the instructor.

Students will present or submit their project using the format specified by the instructor. Each student must contribute meaningfully to the project and be part of project presentation. The instructor will specify a due date for the project. Additionally, instructors may have additional requirements. Students must check with their instructor regarding the presentation topic, format and any additional requirements. Students are encouraged to start work on this project early in the session.

Suggested Formats:

PowerPoint or Prezi presentations
Model based presentation
Poster presentation
Creating video to demonstrate/show the topic
Report in Microsoft Word
Creating animation to demonstrate/show the topic
Course Outcomes:

1. Apply the scientific method to propose a hypothesis and set up an experiment
including positive and negative controls and appropriate units of measurement.

2. Predict the numbers of protons, neutrons, and electrons given the atomic symbol or limited information for a specific isotope of an element and relate them to atomic mass and charge.

3. Determine chemical names and/or chemical formula for diatomic or simple polyatomic compounds and draw a Lewis structure, construct a molecular geometry and determine the polarity for a covalent compound.

4. Balance chemical equations, calculate the molar mass of all compounds in the reaction and demonstrate how mole ratios play a role in stoichiometry.

5. Predict how a change in one or more of the parameters of a gas alters dependent gas parameters such as pressure, volume or temperature.

6. Calculate the concentration and volume of a solution given solute and solvent parameters.

7. Predict the properties of and identify reduction and oxidation agents as well as acids and bases by analysis of chemical formulas, chemical reactions, and solution pH values.

8. Differentiate the common classes of organic functional groups and identify the appropriate common or IUPAC names, applications, and chemical structures for simple organic compounds,

9. Differentiate between the types of radio-active decay at the subatomic level and provide real-world applications, sources, and risks.

10. Contrast the synthesis, composition, structure and functions of major biological macromolecules and Illustrate the process of flow of genetic information.

Chemical formula and biological effect of the chosen opiate/opioid on adolescent and adults

Topic: Chemical formula and biological effect of the chosen opiate/opioid on adolescent and adults


The goal of these assignments is to offer the student the opportunity to research chemistry-related topics of interest while utilizing internet-research skills. Because typical CHM-131 students are pursuing careers in the medical field it is expected that many but not all topics will have medical applications.

Format: Each assignment submission should be 350 (minimum) words in length for the body text. No special formatting, such as MLA, is required. Just make your paper easy to read and follow. Assignments should be saved as Microsoft Word (.doc or .docx) or Adobe Acrobat (.pdf) files. No other file types will be accepted unless preapproved.

Discussion: The discussion should include specific chemistry-related details of the topic to demonstrate understanding of the relationship between material from course lecture and real-world applications. In addition, you may discuss why this topic was interesting to you, what you learned and how this topic may apply to your career choice. Any structures, reactions or figures should not be included in the body of the paper but should be attached at the end of the document and not included in your word count. Discussion throughout the text should refer to your figures. Figures copied from internet sources should be properly labeled as such.

Sources: A Works-Cited page should be included at the end of your submission and not included in your text word count, above. You should use at least 2 individual, credible internet sources. You may also refer to your textbook or other sources in addition to your 2 internet sources. Include a hyperlink (webpage) to your internet sources and the dates you accessed the sites. Example credible websites are available on Moodle but the list is not all-inclusive. Feel free use additional sources.

Different Biofuel Alternatives for Combustion Engines

this is a research article and comments have been added to it with all the errors, I have also included an article attached that I would like to be added to the research paper. another thing to keep in mind is that this is a ACS style paper and it needs to be corrected to ACS if needed. a comment made by my professor was to make sure I included the differences between transesterification and esterification. let me know if anything is missing.

Chemistry/discussion question

Paper details discussion#1
1.How do Svante Arrhenius, Johannes Nicolaus Brønsted and Thomas Martin, and G.N. Lewis each define acids and bases?

2. Go a step further and explain how the three definitions of an acid and base differ.

3. Give an example of an acid and/or a base that is “fits” one of the definitions but not another and explain why.

1.What is a Strong acid?

2. Go a step further and explain how a strong acid is different than a concentrated acid.

3. Give an example of a calculation where equal concentrations of acid solutions may have different pH’s due to differences in acid strengths. Be prepared to explain the calculations.
