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)

Oxidizers and explosives have been used as weapons of mass destruction (WMDs). For this assignment, you are the lead incident commander for Star City Fire Department, which is responding to an explosion at the Regional Federal Building in downtown Star City. In preparing to respond to this incident, you noted that it appears to be eerily similar to the 1995 terrorist incident at the Murrah Federal Building in Oklahoma City, Oklahoma. Information relevant to this case study incident is provided below.
The ambient temperature today at 3:00 pm was 75°F, with winds blowing at 10 mph from the northwest to the southeast.
The Regional Federal Building in Star City is located in a congested downtown area with an interstate freeway passing within 200 yards southwest of the Regional Federal Building.
Approximately 1,550 people work at or visit the Regional Federal Building on any given weekday.
The building alarm to evacuate workers and visitors from the building was sounded immediately.
Assuming that the explosive blasting agent used for this Star City incident is ammonium nitrate/fuel oil (ANFO), address the questions below in your case study.
Based on what we know of ammonium nitrate/fuel oil (ANFO), what are the potential hazards and DOT classifications?
Describe interactions of chemicals, potential for them to react, and the conditions necessary for reactions to occur.
Describe the course of action of emergency response personnel and safe distances/evacuation per ERG guidance (https://cameochemicals.noaa.gov/).
Describe PPE and equipment resources needed.

Here are the details for the final paper submission and presentation slides
Your paper should include the following:
