For questions 7-10, pretend this mixture of 3 compounds is given you and you are asked to separate them. 7. Upon dissolving them in ether (an organic solvent) and adding 8% HCl solution, identify the location of all solvents and solutes (5 total compounds) in the separatory funnel NH₂ OH 8. Justify your choice in Question 7 by showing the acid/base reaction and arrow pushing mechanism that causes your selected compound to be soluble in the aqueous layer.

This is my 2nd attempt to receive help with this problem. The previous expert confused me by saying the answer is less than 109.5? Does that mean it should be 90?  Please provide clarity instead of adding confusion; otherwise the payer loses a question for assistance.  Thank you.

1a. Throughout the experiment, what are some possible sources of error that could have led to someone recovering a significantly smaller amount of table salt (NaCI) than was originally present in the sample mixture. 16. What are some possible sources of error that could have led to someone to appear to have recovered a significantly larger amount of sand (SiO2) than was originally present in the sample mixture.

I understand this answer, but it wasn't one of the multiple choices they gave me.

I'm resending this question because the image on the last one was blurry. I wrote the prompt and steps and helpful conversions to figuring out the real world problem on my scratch paper, how do I solve for this problem?

The study of detecting small quantities of substances in samples would most likely be performed by a chemist in the branch of chemistry known as ___ . organic chemistry biochemistry inorganic chemistry analytical chemistry physical chemistry
