Not a chance it will be that high.
Does anyone know when the free response will be released? I thought they said 48 hours…
Thanks! @cedv16 Will the answers be posted too so I can total up how many points I got or will they not be released until later?
@destined4harvard They make the scoring guidelines at the ap reading.
Was there a mistake on the lewis structure one. I think there was. They said one bond longer than the other two, which meant carbon would need more than an octet, which makes no sense.
yeah! @ChessKing10 thats what i thought too…
@ChessKing10 @neha3130 I got this question wrong because I was rushing, but the question wasn’t a mistake. There are two resonance structures, each with one double bond, so the two bonds are not exactly double or single bonds, so they’re still longer than the single bond. Sorry if that was confusing- just look up HCO3- on google and you’ll see
For particle-particle interactions, did you guys say ion-dipole forces between H and Cl- and O and Li+? Also, for the experiment to run to determine if it was conductive or not, did you guys say to measure its conductivity by running some type of current through it?
For the particle particle interactions, I said to see whether it conducts when in aqueous solution @CGlynn
@iamnotironman See, thats where i was confused. Cause technically a double bond is shorter than a single bond due to the attraction… but i think i get what you mean
@CGlynn yes and yes
What did you guys do for #6 on the FRQ? I just found the limiting reactant and assumed it all dissolved because K was super big but I wasn’t sure
@iamnotironman Yes, Ba 2+ was LR and just do stoich to find the product moles, then divide by total Volume. I think it ended up being like .100
@CGlynn yay I think I got that!! What did you say for part 2?
@iamnotironman I said no change because since the reaction goes to completion essentially a change in concentration will not affect the moles of a reactant remaining.
@CGlynn Same!! But I was worried because I thought it was a le chat’s-type question…
I thought you had to set up the K equation and plug numbers in… I got something x10^6 on #6 because the value of K was so large, but maybe I messed that up… @CGlynn
Also, where can the link to the questions be found on the college board website? I know someone dropped the link here, but what did they type in to find it?
when are scores released?
What pH’s did you guys choose for #4? I only chose a pH of 1.
i put 10, 11, 12, 13, and 14.
