Also on 2014 FRQ #2 why don’t you divide by total volume in part D?
@APmaster007 I got 33/60, which is a little more than 50%, and you need a little less than 60% total to get a 4.
http://appass.com/calculators/chemistry Also you guys can predict your calculated score here/see how many you need to get right haha
@portraiture97 that’s based on the old exam.
@portraiture97 , but that’s out of 75 on the mc. It’s an outdated calculator.
??? you can just do a conversion/set up a proportion then…
can someone help with part D on 2014 frq?
@portraiture97 it’s not that easy. The curves on these new exams are nowhere near as lenient as they were in the past.
@APScholar18 - Which question?
Let’s just hope for the best then!!
I would really appreciate the 2014 MC too, my teacher never got it for us. I really could use it.
is an ionic bond an IMF?
@mathman97 NO IONIC BONDS ARE INTRAMOLECULAR NOT INTER
INTER IS BETWEEN MOLECULES
INTRA IS BETWEEN ATOMS
@mathman97 no, because bonds are different than intermolecular forces. IMF occur between molecules, while bonds occur within molecules. Most ionic bonds show dipole dipole IMF though, I believe. For example in HCl there’s an ionix bond between H and Cl. There are dipole dipole forces between one HCl and another HCl molecule.
I’m pretty sure that’s right.
^There’s also ion-ion intermolecular forces, though
is the 2013 test the test before it got updated?
^ right, I think ion-ion is a special case of dipole dipole. Is that true or are they two completely different things? And I think there’s ion dipole too.
@stemscholar - I think ion-ion is just electrostatic, which is ionic, so there’s ionic intramolecular forces AND ionic intermolecular forces? Can someone confirm?
@glasshours #2 part D FRQ 2014
ion-dipole would be like an Na+ ion in solution attracted to the negative dipole at the Cl- of an HCl molecule
