NLM doubt - Q74 (red is key answer)
the wedges aren't fixed right? if they're moving in opposite directions then how would the cylinder remain in contact with both of them?
this is probably a stupid doubt i'm having, so i'll apologize in advance.
edit: understood that they will eventually separate, and it's asking us for the velocity of the cylinder before they do.

PnC/Relations, prime number counting problem
i think there would be 9. 2x2 isn't counted, so the multiplier can only be chosen from 9 distinct numbers, not 10, while the multiplicand is 2.
9 for each multiplicand, 10 total multiplicands, so 90 ordered pairs from that, and then the numbers' pairs with themselves like you said at the end, so the total number of ordered pairs would be 90+10.
i didn't realize the thing that was later pointed out by opt either :').

Naming Conventions
sorry if i'm too fixated on naming conventions and missing what you were trying to convey 😅

Naming Conventions
to clarify - what i was talking about is how since you can't always classify a compound as inorganic or organic, i assume it'd be confusing naming such compounds. it does seem like the compound with palladium at the centre is named using some convention though.

Naming Conventions
that was a nice read, and it does have to do with the distinctions i was trying to make at first with specifying that the compound be inorganic so as to make clear that i'm not talking about organic nomenclature, but it makes me feel that naming conventions are even less reliable than i initially thought, and that you only gain intuition about naming compounds as you go on studying chemistry :')
