Are Bunsen burners and hot water baths usually provided in invitational competitions such as Princeton?
They should be. That's on the event supervisor.
Have yall ever had to determine the direction of impact for glass?
I've personally never seen it on any tests I've taken, nor have I used it yet on tests that I've written. I think the reason why would be that maybe supervisors don't wanna write a problem for it or a lot of the images may not be able to show much detail of the impact spot beyond the spot where it hit and the resulting cracks surrounding it.
Thanks for the idea tho, I’ll consider it for the future
The peak on the rightmost side is tells you the molar mass of the molecular formula. You see that the rightmost peak is around m/e of ~46, which corresponds to the molar mass of the ethanol
I was asking for the molecular formula, not the molar mass. Sorry for any confusion.
Usually the molecules used for these are taken from a list of carbohydrates; find a list for this and match the molecular weight to the carbohydrate.
In reality it's waaaaaayyyy more complicated than that. It's quite an advanced organic chemistry topic, actually. Those textbooks may have some info on that.
