disregard anything that includes lab 11. In this lab report I need an abstract, introduction, experimental procedure, and results and discussions. It needs to be cited with journal articles.

You were asked to evaluate the results of GPC analysis of PMMA (poly[methyl methacrylate]) polymer. Separation was made on PLGel universal column (styrene-divinylbenzene 100 – 107 separation range), RI detection, and eluent – THF, calibration by polystyrene standards. Weight and number average values were calculated directly from chromatogram. Are the calculated Mwand Mn values, correct? Explain why.
2/ You are separating benzene, toluene and ortho-nitrophenol on RP column with acetonitrile/water as eluent. How the variation of the eluent composition (% of acetonitrile in water) will affect the selectivity between benzene and toluene and between o-nitrophenol and benzene? Explain.

I have a chemistry task that starts at 12:30 Pacific time which is in one hour and it must be completed within two hours starting. it is 25 questions and only answers are required no need to show any work. answer must be provided quickly because it is a timed task.

hello I have a general chemistry task that starts at 12:30 pacific time which is in an hour and 30 minutes. it is 25 questions and must be completed with in 2 hours of starting so answers must be provided quickly. only answers are needed no need to show any work.

Option 1:
We will begin this topic by practicing the use of the scientific method. The steps of the scientific method are: observation, hypothesis, experiment, results, and theory. Using your understanding of the scientific method from your readings and lessons, you will be applying this knowledge to a real world situation. Take a real world scenario in the news, or another outside source and apply the scientific method, being sure to detail the controls on your experiment.  Describe a result that would confirm your hypothesis.
Minimum of 3 sources cited.
APA format for in-text citations and list of references.

I will have all the attachments please do the Excel calculation there is
an instruction file for that. and then please do an Abstract and
introduction there are also two attachments for that after that please
do the discussion part and the error analysis. and one last thing please
do 1-7 calculation part you only need one sample.
