Lab reports must be turned in Canvas by 1:00 pm the day they are due. Late reports will not be graded. Use this format for the file name: LastName_FirstName_Rep #X.
The reports must be typed using font size 11 (font: Arial) or 12 (font: Times New Roman) in 1.5 line spacing, with 1-inch margins. The collected data and all calculations steps must be typed and be included as part of your lab report.
Your lab report must include the following sections:
Title page and abstract (5 pts) – The abstract is a brief summary of the objective, experimental results (the calculated molar mass of a gas, errors, etc) and any significant conclusions. Typically, 50 to 100 words long.
Introduction (1 page, 15 points) – Statement of the purpose of the experiment and a brief outline of the theory and background, citing pertinent equations and citing references whenever appropriate. Do not include the same content found in the handouts or the textbook; instead based it on the references you are citing. It should be at least 1 page long. Equations and/or figures included in the text will not count toward the required minimum length.
Experimental Method (5 points) – Brief outline of the experimental procedure or methodology.
Results (20 points) – Experimental results in full detail, making use of tables, plots and figures when appropriate. All results must be reported with proper units.
All calculations (all steps) must be shown with their proper units, and these will be included in the Appendices section.
Discussion (minimum half-page, 30 points) – Data analysis, data interpretation and in-depth, meaningful discussion of the results that includes a close examination of the results and possible sources of errors, relationships among variables, etc.
References (At least 1 reference, 5 points) – This reference must correspond to primary literature (peer-review articles) DIRECTLY related to the experiment performed. They must be cited in accordance with ACS guidelines (provided in a document uploaded in Blackboard).
Appendices (20 points) – Include all your calculation steps with proper units (don’t omit steps; your instructor must be able to determine how each result was calculated so that you can receive credit). Include any other supplementary material in this section.
attached is part 1 and 2 of experiment. you must do calculations and show your work

1. In your own words, compare the following pairs of terms and then provide an example of each.
a. Mechanism of action versus mode of action
b. Local effect versus systemic effect
c. Statistical significance versus biological significance
2. Compare chronic exposure to acute exposure. Research and discuss at least one manufacturing toxicant that causes adverse effects from both chronic exposure and acute exposure. Identify the toxicant, what it is used for in manufacturing, how exposure occurs and the observable adverse effects that it causes
3. Using the dose-response curve above answer the following questions:
a. Which substance has the highest potency? Explain your answer.
b. Define NOEL. What is the NOEL range of substance B?
c. What is the ED50 and TD50 of substance A? How did you determine these values?
d. The therapeutic index of substance B is 9. Comparing substance A to substance B, which one would be considered safer? Explain your answer.
e. At what dose is the maximum toxic effect of substance A observed? Explain your answer.
f. At what dose is threshold reached for substance B? What is the threshold of a substance?

Choose a pharmaceutical drug and answer the following questions about the drug:
What is the IUPAC chemical name?
Who discovered it or what company discovered it and when (if available)?
What does the compound look like? Provide a picture of the compound.
What are the functional groups in the compound?
What are the medical uses for the drug?
What is the mechanism of action of the drug (how does it work to affect the disease or malady)?
How is it usually administered (ex. IV, pill, etc.)?
What are the potential adverse effects of the drug?

Take on the identity of an element and write a creative story involving your element. Your story will contain a part that is fictional but will also weave in facts of your element. Examples of facts are chemical and physical details of the element, the discovery, history and current applications. Below is the attached example of the assignment. Number of words – 1100 – 1500
