first photo is pipetman exercise values for data analysis and results /question discussion
second and third photos is buffer exercise data analysis and report /questions and calculation

for the lab report you basically need to make your own
we will be doing a lab experimenting on wee wee pads (the pads dogs pee on)
the brand of the wee wee pads: honey care all absorb training pads
for the intro: Get information about what is in these pads. (what is in the in them? what absorbant (absorbent in it is actually polyacrylate) how to extract this absorbent from the wee wee pad. what different polymer are in them? how would you identify it (by IR and by a microscope for this lab). in previous lab I did we did IR of polymers to determine what organic groups are in different random items we bring to class. we used the Nicolet is5 IR spectra.
you would just need to do a procedure, intro, the chemicals you might think we will use, basically everything besides the data and conclusion since that needs to be done after the experiment is over.so do the beginning and stop when you get to the data part.

Please read this document first. This document also contains the lab report pages that you will need to complete for the lab.
Laboratory #1 Experiment 2: Measurements
The purpose of this assessment is to provide practice and instructor feedback in correctly making and recording measurements with the correct number of significant figures.
This assessment will be graded.
Directions:
Complete Laboratory #1: Measurements. You must show all of your work for credit.
Detailed directions for the laboratory are provided in the virtual laboratory document provided in this assignment.

9) Physical or Chemical?
a) Unsaturated fats are liquid –
b) O2 binds with Hgb –
c) metal in hip joint implants is not corroded –
d) antacid tablet neutralizes acid –
e) Melanin pigment is brown –
11) Alcohol (l) is frozen to solid, then melt back. Have the molecule been changed by the process?
15) Hydrogen Peroxide H2O2 can be changed to water H2O and oxygen O2. Use the term homoatomic or heteroatomic to classify hydrogen peroxide.
23) classify as homogeneous or heterogeneous (mixture)?
a) muddy water – b) gelatin – c) normal urine – d) smog-filled air – e) an apple –
f) mouthwash – g) petro jelly –
37) 25km –> miles (1km=0.621 miles)
25 km x 0.621 mile
1km
38) mass 4.0kg –> pounds (1kg=2.2 pounds)
4.0kg x 2.2pounds =
1 kg
47) Which ones are incorrect in terms of scientific notation expression? Try to write the correct way (optional).
a) 4.2×103. b)6.8×104. c) 202×10-3 = 2.02×10 d) 0.026×10-2 = 2.6×10-4. e) 1×10-2 f) 74.5×105 = 7.45×10 6
54) ** Calculator work. Do the multiplication, and express answers in scientific notations. (8.2×10^-1)(1.1×10^-2) = 9.02×10-3
56) Use calculator to find your answer directly.
a) (144)(0.0876) = (1.44×102)(8.76×10-2) =
58) Use calculator to find your answer directly.
3.1×10^-3
(1.2×10^2)
77b) 3.0 yard x 1m = 2.74 m

Professor is allowing one side paper notes to have during exam. need help writing important concepts to remember for my cheat sheet.

-We used “1.10g ” of acetanilide
-the final mass of the product is 0.45 g. the melting point of product is 221.3 degrees celcieus
-I will attach the instructions. Please rewrite the procedure yourself and not copy and paste the one I provided. It should be similar to it.
– In the post lab you can find the pictures such as IR and TLC. My yeild calculations and IR interpretations are not 100% correct.
-Citation style: ACS.
Thanks

What are the main requirements of this assignment? ð Part 1: Create a PowerPoint presentation to inform: 1. In your words, describe what is Environmental Justice – What does it mean to you?, and 2. Identify three areas of need of Environmental Justice in the Atlanta metro area. Give descriptions in your slides (Explain what it’s about.), and prepare a reference list as background for the information in your presentation (If someone is interested in getting more information, where could they go?). ð Part 2: Choose two groups working for Environmental Justice in Atlanta and prepare a paper that answers the following questions about each one: 1. What are the goals for this group? 2. What are your thoughts about this group’s work? 3. How can someone in your profession help to address these issues of Environmental Justice? How will the assignment be evaluated? Evaluation is based on how well the project fulfills the stated requirements. The following questions will be asked when reviewing the project: ²Did the writer provide a complete explanation of the topic? Did the writer include meaningful references to support this explanation? ²Did the writer identify Environmental Justice groups in the community? ²Did the writer discuss their thoughts about the groups’ work? ²Did the writer discuss how their profession relates to this topic?

use calculations and make sure its not done by Ai. The pdf below explains everything so just use that and follow it.

A formal lab report has to be done in APA format about the extraction of essential oils from cinnamon using the article provided. Not much information about the assignment was given other than it has to be 5-6 pages in APA format. Use as many references as needed including the attached article.

Please see files.
We are group of 3.
One of my group members chose to do the Malvern figures and did the table , i am required to do (1.2)
