This is a lab report on a prior lab. I will provide everything you may need. It will consist of an introduction, sample of calculations, results, conclusion, and discussion (needs 2 references).

Hello I need someone to write this lab report for me I have included everything needed.please attach the screenshots in the report and follow the outline. Also it doesn’t have to be that long

*only organic chemistry expert bid*
fix my mistakes
I am redoing this assignment since I got it wrong, that’s why i attached the rubric and comments to get it right this time. You have to follow the rubric fully and complete all steps.
I also attached answers from the first time I did it just for your reference, you can fix my old mistakes or do a completely new problem. your choice
This assignment has to show all molecules drawn, all arrow movements, don’t just explain and write words. You have to SHOW and DRAW. MUST OR FAIL THE ASSIGNMENT. need visual drawings not just paragraphs of words
Don’t use AI or chegg. It will be checked, if I wanted answers from chegg i wouldn’t be here

I need someone to make me a script of exactly what to say for a video assignment in organic chemistry and I also need drawings on the assignment as they are required. Script doesn’t have to be too complicated and should be for about 3 minutes long. I have attached everything you will need.

Why atomic radii decrease from left to right in d-block?
The atomic radius goes on decreasing while going from left to right in a period because the atomic number of the elements increases which means the number of protons and electrons in the atoms increases (the extra electrons being added to the same shell).

Discuss the process involved when one is pricked by a sharp object on the finger, how does he react and why?

1. a. How many moles of N2 gas occupy a volume of 775 mL at 8.40 atm and 335 Kelvin? b. How many grams of N2 are formed from the above?
2. A sample of gas at constant temperatures has a volume of 400.0 mL and a pressure of 760.0 torr.
What volume (in Liters) will it occupy at 595.0 torr?
3. At a temperature of 0C, a gas occupies 22.4Liters. How hot must the gas be, in celsius, to reach a volume of 25.0Liters?
4. A Student obtained a balloon containing 0.500 moles of helium at a volume of 1.75 liters. The student’s lab partner added 0.250 moles of nitrogen gas into the balloon. The contents of the balloon were held at constant pressure and temperature. What is the balloon’s final volume (in liters).
5. a. A mixture of gases contain 64.5 grams of oxygen gas, 50.0 grams of nitrogen gas, and 150.0 grams of chlorine gas. Calculate the mole fraction for each. b. If the total pressure of the gas sample was 5.00 atmospheres, calculate the partial pressure of each gas.
6. Which of the following gases will have the highest velocity?
a. Cl2 b. O2 c. Kr d. C3H8 e. F2

By now you should have completed several of the most important sections of formal report. It is time to combine them and add some other items such as Title, Reference, etc. Make sure that you will revise your formal report based on comments your TA provided to you during these individual practices. Once again, the following files may be helpful, though you may have read them before:
FORMAL_REPORT_INFORMATION.doc
Formal_Report_EXAMPLE.doc
Warning: Please read the following very carefully!!
A tool called “TurnItIn” will be used to check similarity (or originality) of your completed formal report. The originality report may be used to discipline students for plagiarism or other academic misconduct found in grading your formal report!!

Prelab Questions – please write me a detailed procedure ( I don’t want to read the lab manuals) and also have answers for the following Experiment Method
Understand the method and how it works.
What is being measured? What is being studied? What phenomena is being studied? What happens to the chemical system during measurement?
Expected Results
What results do you expect?
What will the raw data look like? What trends are expected?
How will you process your data?
What things will be compared?
Physical Significance
What understanding of the chemical system do you gain by performing this experiment?

here is a pre-Lab. We will recrystallize caffeine. Please do an EXCELLENT intro, as you indicated that you did not know about this. You all did do a lab in 1107 if you went here on Alum crystallization, but this is somewhat different. Please write a prelab for doing recrystallization from water, and from ethanol. Let’s use about 2.5 grams of caffeine.
These labs are pretty interesting actually. there is no actual protocol on what to do – you kind of just make it up based off of what we have already done in lab. you will research what you can do for this lab and make a protocol for it. ill attach a lab report I have previously done so you can get a better understanding. you will do the first half of the report since I haven’t done this lab yet. you will make up your own protocol get creative for chemicals attach the SDS sheet in a link too. follow the guidelines. do not work on observations since lab hasn’t been done yet. do the intro, procedure, protocol, the equipment and chemicals and that is it you need to research this topic beforehand and write about it in the introduction followed by the objective of the lab. if you use sources make sure to use superscriipt format for it. superscriipt goes after the period. include It in references. intro should be at least a page long. it should be detailed. you need to also do the lab equipment portion as well as the reaction and chemicals. do not morph the formatting of the template. remember this is a PRE LAB REPORT
you will research and write a protocol.
