I have attached what the lab was over, my data, and the instructions on what the lab report should have in it. Also, there is an example of an old lab report for guidance. Some math might be involved with showing the calculations. Please follow the guidelines and if you have any questions feel free to contact me.
Background/Introduction
The general purpose and background of the chemical basis for your experiment should be given. Any chemical equations should be stated. Include any known limitations to the procedures or equipment
that limit the quality of results obtainable by that method. A reference to the procedure should be given
and any deviations from the procedure should be noted. The background/introduction should be
summarized in your own words. It cannot be copied from the lab manual.
Results
Your raw data should be included in the report in tabular form or included using a report form (which will
be provided). Extra copies of the report form are found on Blackboard in PDF and word versions.
Sample calculations must be included and may be handwritten on a report. (If a report form is used, in
the results section of your report, simply indicate “See attached report form.”)
Discussion
A discussion associated with a lab report in Quantitative Analysis Lab should be a discussion of the
quality of the results obtained in the experiment.
1. One should clearly and briefly state only the final results. (If three trials were performed, only the
average and relative standard deviation are to be reported. DO NOT restate each trial’s result. E.g.,
“Of four trials, the average was 5.934 g with an RSD of 5.32 ppt.”)
2. Then, discuss the quality of the results. Are the results accurate? Are the results precise? Why?
What did you do to insure accuracy and precision? Do not make qualitative statements like, “The
results are relatively precise.” (Note: How precise is relatively precise? Is this better or worse than
“pretty precise”?) If two sets of titrations were done (e.g., one standardization and one
determination), you might state that the precision in one set was better than the other set.
3. Were there any known sources of error? This pertains only to your experiment. If you forgot to zero
the balance, then state it in your discussion. If you did not have that error, then do not write it in your
discussion. Human error is not a valid source of error. You are not to guess at every possible error
under the sun. ONLY state the errors you observed.
4. Run a Q test (explain and elaborate why or why not we need to run one)

This week, consider the following terms:
Entropy
Second law of thermodynamics
Spontaneous change
Free energy
Third law of thermodynamics
Respond to the following in a minimum of 175 words and also leave two separate comments of 50 words each in the note section of the PowerPoint please and thank you!
Choose at least two terms from the list, and answer the following questions for each term:
What familiarity and prior knowledge do you have about the term?
What does the term mean in everyday language to everyday people? Use examples to help describe your thoughts. How do people use the word?
What does the term mean in technical language to chemists?
How is the term related to the course student learning outcome: Explain the laws of thermodynamics?
What are the similarities and differences between the everyday and technical meanings and uses of the term?
What impact might the similarities and differences have on your learning of chemistry concepts in this course?

The Ligand and Field Strength pdf is the lab and all the guidelines for the lab report.
The image is the data table that must be included in the lab report filled in with the concentration values that must be calculated. The pdf files for samples 1 to 6 are to be used for the data analysis.
In this last exam module, we will review the material you learned in the previous four modules to help with your comprehension of material for the exam. In your initial post to the discussion, respond to the following prompts:
Think back over the last four modules. Which topic made the most sense to you and why? How would you explain this topic to a layperson (someone who has never taken a chemistry course)?
Which topic made the least sense to you?
How does one or more of these topics relate to your life outside of chemistry class? In other words, how are these topics relevant in the real world?
Share two or three study tips that you plan to utilize while studying for this exam.
Least Sense – Limiting Reactants in Everyday Life
Most Sense – M9. Discussion: Conceptual Problem Solving
According to Charles’s law, the volume of a gas is directly related to its temperature in kelvins at constant pressure and the number of moles. In your initial post to the discussion, respond to the following prompts:
What if there was an inverse relationship between the temperature and the volume? How do you think the world might be different? How would this change our day-to-day lives?
Pick one of the following questions and try to answer it using one of the laws you learned in this module:
How do spray cans work?
Why do you need to fill up your tires with air on a cold day?
Why do soda cans explode?
When you inhale, your diaphragm increases in volume. How does this allow you to breathe?
How does a syringe fill?
How does filling a basketball with air increase its volume?
Electronegativity is defined as the relative ability of an atom in a molecule to attract shared electrons to itself. We use differences in electronegativity to account for certain properties of bonds. In your initial post to the discussion, answer the following questions:
What if all atoms had the same electronegativity values? How do you think bonding between atoms would be affected?
What are some differences we would notice?
