Chemistry Supercritical Extraction Lab Essay Assignment
There are two parts of assignments:
Assignment 1)
Post-Lab Report assignment (Experiment 4). It will not take more than one hour to complete it
You already do the pre-lab assignment (Experiment 4) for me last week. So, it’ll be easy for you to do the post-lab report. Also, I’ll upload a picture of the data and some information to complete this post-lab report assignment. I’ll upload to you the pre-lab report (Experiment 4) to check it and make it easy for you.
Please read the instructions carefully for this assignment because it’s important and make sure you do exactly what it says in the instructions and mention everything is needed on it.
instructions

Pre-Lab Report (Experiment 5)
Very simple assignment, please read the instructions carefully to know what you should do.
This assignment is very easy, and it will not take more than half-hour to complete it after you watch the video to know what you need to do. So please try your best to do it.
I posted a link for the video; you have to watch the video carefully to get all information needed in the pre-lab assignment. Please don’t forget to collect the data when you watch the video if it’s required.
Also, please make sure you follow the pre-lab rubric file I’ve uploaded here. In addition, please make sure you write your own words when you fill the information in the pre-lab assignment.
If there is anything you need for this assignment or you don’t understand something in the instructions, please feel free to ask me.
This is the link for the video
I post the link for the video, and I think now you can watch the video it doesn’t open with you please let me know. Please don’t forget to follow the pre-lab rubric.
I’ll upload the pre-lab rubric to let you see it and make sure that includes everything that is needed on it.
