i showed that it reacts with OH to form NH3 and water which is basically showing the same thing

i think there's a mistake in their solution to 31, the graph is skewed in that scan so they accidentally drew the line down to 0.044 instead of 0.046

I knew it was between A or B but i didn't know which had the + on it and i didn't know if that was the charge or not 😭 so i just had the one where the thing that didnt contain the O had the + which was A i think

i genuinely cant remember what i put for 14 so i might have had the same answer as u, possibly not tho idk

I think i got something like 1D 2C 3B 4D 5D 6C 7A 8C 9C 10A 11C 12B 13A 14(idk but i think B?) 15B 16B 17(idk but i think A) 18(A i think) 19(also A i think) 20D not sure that these are exactly what i put for everything but i think it's decently close

sorry meant to reply, ^

i don't know if they're talking abt something completely different, but you might have been able to use concentrations to find how much was added instead. since [CO2] = [CO] let [CO2] = x x/x^2 = 10 x = 10x^2 1=10x x = 0.1 for the conc of both

that test was so much nicer than i expected. i was thinking i was gonna get screwed over and maybe a raw 70 but if everything goes right i might get 90+

2021 is definitely easier than 2022 and 2023 imo. also i would say the actual content of 2023 is harder than 2022, but 2022 was more difficult in terms of interpreting the question because from like 13c onwards each question contained massive paragraphs

im expecting a raw 70-75 hopefully... i messed up quite a bit of stuff. Ik that scales to e4 but my rank might come back to bite me and drag down my mark. hopefully that doesn't happen...

only part of 14 i finished was part a lol, i got most of c(i) but the rest was just waffle and messing around w stuff that i probably will get nothing for

it's in the textbook!!! how could you have missed it!!!!

he's just messing with u guys 😭

the question gave that morepopulation(a_city, b_city) means a_city has higher pop and the same with highercrime(a_city, b_city) and it said what constitutes one city being better than another (higher pop and lower crime), so it said write two facts which result in f_city being a better city than...

i put exactly what u put as well. i was confused about the desk check though, i completely filled up the table and only got through to the Q input so i wasnt able to try X. also the program would have encountered an error right after my last desk check line because it would have tried to read a...

the two that he mentioned were the facts needed for f city to be a better city. The rule would be something like "bettercity(X,Y) :- morepopulation(X,Y) , highercrime(Y,X)" i also forgot the names of the facts given in the question but you get the point

i picked the maintenance option :(

i cant be the only one who had never heard of a post implementation review. i narrowed it down to 2 options but im pretty sure i guessed wrong 💀

some of those questions caught me off guard, hoping i can still scrape a raw 90+. did literally anyone know what linking was??

Thanks for your help
