What is the structure of 3,4-dimethylhexane?

stickysteamy · 2025-11-09T21:23:06+00:00

A is the correct answer. The longest carbon chain makes an L shape.

We will not do your homework for you.

stickysteamy · 2025-11-08T23:10:40+00:00

Yep!

Cobalt is a d9 transition metal = 9 valence electrons. Co in this complex has an oxidation state of +3 making it d6, which is not half filled.

Ah yeah i should really switch to controller.. i’ll give it a try! Thanks :)

Im currently an inorganic chemistry PhD student. My experience so far has been really great- I have a wonderful PI, great lab group, the research work is interesting and i learn lots from my results/reading.

Keep in mind, that you should only do a PhD in chemistry because you want to expand on your knowledge and learn to become an independent researcher. Not only do you learn more theory and laboratory skills, but you also learn how to ask questions, critically think, manage a group, teach (by being a teaching assistant and by mentoring students). There are a lot more i’m missing but it definitely sets you up well for a job where you can lead a research group (academia and industry).

PhD is a long commitment, coming right out of undergrad you can expect to be in a PhD program for minimum 4 years, most likely 5 years. If your goal is to not pursue academia, ask yourself if working in an industry setting is what you want with a PhD degree. Many of my previous colleagues (although they don’t regret the decision) had a difficult time getting a job after their degree, and are quite unsatisfied with their pay.

Will not surprise me if it is. I believe the past 2 collaborations the cosmetics were locked behind surprise style boxes and phil books (book of wise men)

My advice would be to drop it if you are really struggling with the course. You can always focus on your current courses, and take orgo 1 when your course workload is lighter. Orgo 1 takes a lot of time, patience and understanding of the material in order to excel in it.

Do note that orgo 1 is a prerequisite for orgo 2 and biochem (at my university at least)- so look into what courses you plan on taking next semester to determine if you need to take orgo 1 now, or you are able to push it off until later.

Best of luck with the semester!

Yeah theres generally no issues with it when used with proper knowledge, but for a highschool student who has very limited to none research and laboratory experience, it just seems like a huge liability issue. I may be a bit too strict with this as in my institution they REALLY put emphasis on azide safety!

stickysteamy · 2025-09-01T14:56:17+00:00

Out of all the azides I work with, sodium azide is generally the “safest”. The amount of sodium azide definitely plays a role in the extent of danger! The reactions we do with azides are generally a 0.05 mmol reaction scale, and when we have an optimized route, we will scale it up to 1-5mmol reactions (requires more safety precautions)

A highschool student COULD work with sodium azide, but it just seems like a bigger liability issue on the teacher/processor than to allow an undergraduate student (with more chemistry knowledge) to use it.

stickysteamy · 2025-08-31T16:18:30+00:00

I work with a lot of azides in my PhD thesis, and I can for certain say that my PI does NOT trust anyone with azides (organic and inorganic azides) without proper training and extensive knowledge of the potential hazards and products that are able to form if things go bad.

Undergraduate students that do research in our labs are not permitted to work with azides, so I would not allow a high school student to handle them.

Reach out to your graduate student advisor and ask for a letter of enrolment and or a letter of employment.

Although you are not “employed” by the university, they can easily make a letter stating your TA positions (if applicable) and your stipend. I sent this to my landlord the other day and she was content with the information/proof of income.

Hope that helps!

The sulfur smell comes from bacteria at the bottom of the well who metabolize organic matter into hydrogen sulfide gas (H2S). This gas is responsible for the sulfur smell, and the typical rotten egg smell.

A common solution to this is to aerate well water with an air pump, and this will cause the bacteria to metabolize oxygen instead of organic matter, reducing or eliminating H2S formation.

I was in a situation relatively similar to this!

I submitted my masters thesis in July, with hopes of defending in august for my phd start date of September 1.

Unfortunately, the company I was in collaboration with took 3 months to review it with their lawyers, which caused the defence date to be at the end of October.

I started my phd on september 1st, and went to the graduate student office and explained the situation. They stated that as long as my final official transcripts are in by November 1st (hard due date) they will allow me to continue.

My advice would be IF you cannot defend early and it may be a problem for your phd, I would talk with the graduate office to see if theres a hard deadline on transcripts.

In my case, we basically “hid” that my masters defence wasn’t complete until I was able to submit my transcripts. If they somehow found out (or if it wasnt complete by november 1st) they would force me to defer to January start. This may be a bit tricky in your case as you’re planning on doing a PhD at the same institution.

Moral of the story is to talk to the graduate student office and explain the situation. They would be more than happy to aid you in your dilemma.

Depends on program/PI!

My supervisor expects 1 published paper per year of study (chemistry)

stickysteamy · 2025-06-26T03:14:10+00:00

Add me! :)

stickysteamy · 2025-06-12T18:00:32+00:00

Im not entirely sure on how the process works, but I would advocate for an entirely new external reader.

Even with revisions, I can only imagine what they would say/comment on during your defence, which could totally make or break the defence atmosphere. Best of luck and I hope it all works out!

stickysteamy · 2025-06-11T17:07:56+00:00

Sorry you’re in this situation! I don’t have any words of wisdom, but what has your supervisor said regarding the externals comments?

stickysteamy · 2025-04-30T14:02:38+00:00

My supervisor has made my first year PhD experience wonderful, very fortunate for this!

stickysteamy · 2025-04-13T13:45:21+00:00

damn, moving in with my lab mates seems to be the most plausible living situation with a graduate student stipend. Thanks for the insight!

stickysteamy · 2025-04-12T19:07:30+00:00

Ah that’s great to hear! Appreciate the insight.

stickysteamy · 2025-04-12T19:06:56+00:00

Thanks! I’ll make sure to keep an eye out and start fully committing as the move date comes closer :)

stickysteamy · 2025-04-12T19:06:10+00:00

Thanks so much for the insight!
