<p>I wouldn’t be surprised if there was an empirical formula question on there. They haven’t done one since 2003 and a lot of kids forget this “easier” topic.</p>
<p>I have seen at least bonding/Lewis structures and IMF forces on almost every Part II, so I highly doubt that if they even do the changes for the descriptive chemistry topics, it’d be hybridization/atomic theory at most, (paramagnetism and the like).</p>
<p>2008: Kp/Kc, Kinetics, Electrochem / Gravimetric Analysis, Lewis structures/atomic theory/bonding/IMF forces
2007: Ka, Thermo, Bonding energy, Electrochem / Titration, Lewis structures/hybridization/bonding
2006: Ksp, Thermo, Stoichemetry / Beer’s Law - Spectrophotometer, Lewis structures, periodic trends/physical chemical principles
2005: Ka, Stoichemetry, Kinetics/ Synthesis of a Salt Lewis structures, Bonding theory,IMF, Electrochem</p>
<p>Revised predictions:
Q1: Kb or Ksp
Q2: Thermo(calorimetry lab?), stoichemetry
Q3: Electrochemistry
Q4: net ionic rxns
Q5: Lewis structures/hybridization/bonding theory
Q6: isomers/IMF forces</p>
<p>Can someone else better predict 5 or 6?</p>
<p>I agree with Serafina. They seem to ALWAYS ask about VSPER and hybridization/atomic theory.</p>
<p>@ Serafina: wouldn’t the fact that electro’s been on there the last 2 years greatly decrease the chances of it being on this year’s test?</p>
<p>It could, but electrochemistry is one of the chapters that doesn’t get taught in most AP classes, due to it usually being the last chapter in the book, according to my teacher. It’s also one of the most confusing concepts if not studied properly. </p>
<p>What does everyone else think it should be, then?</p>
<p>I hope for the equlibrium one its Ksp not Ka or Kb lol.</p>
<p>im looking over petersons review book and they have a section on “dipole moments” and “vectors” … its in the “molecular geometry” chapter… ive never seen this before? would it ever be on the test?</p>
<p>Do any of you know how the scoring for the AP Chemistry test is?</p>
<p>For some reason my Kaplan book doesn’t explain it.</p>
<p>I know for APUSH there was an online calculator that solved whatever values you input into it. Do you guys know if there is one for AP Chemistry?</p>
<p>It’s my birthday and I am skipping school to study chemistry. ■■■.</p>
<p>Happy Birthday! So sorry to hear that.</p>
<p>Not sure, check the scoring rubric for AP Chem? I also think someone posted it earlier here. It’s 50-50 for both the MC and the FRQ, but the FRQ is easier to grab money points. Aim for a 70% on both.</p>
<p>Vectors and dipole moments are really small. Dipole moments are only used to determine the length and strength of bonds, from what I remember?</p>
<p>You usually want about a score of 40 for the MC and a score of 60 for the FRQ. A scaled score of 100 is a 5.</p>
<p>haha thanks. I’ve talked to two AP chem teachers in two different schools and both of them predict that the first question will most likely be on acid-base equilibrium, and one of them is leaning towards a weak base equilibrium since weak acid was a couple years ago.</p>
<p>It should be graded like this:
[(MC correct) - (1/4 X Number wrong)] X 1.0667 = Weighted section I
FRQ1: (Points out of 9) x 1.7778
FRQ2: (Points out of 10) x 1.600
FRQ3: (Points out of 8) x 2.000
FRQ4: (Points out of 15) x 0.5334
FRQ5: (Points out of 8) x 1.500
FRQ6: (Points out of 8) x 1.500</p>
<p>Composite Score:
160 - 108: 5
107 - 86: 4
85 - 62: 3
61 - 43: 2
42 - 0: 1

<p>That’s cool! Now we have to figure out the rest of the FRQ, since Kb or Ksp will probably dominate tommorrow. Stoichemetry, Kinetics, Thermodynamics, Electrochem are our tasty choices. I think Stoichemetry will be on there tommorrow, since it hasn’t been on in years, but I wonder what else. Perhaps some tasty Thermo with G = S - TS? Sexy kinetics?</p>
<p>What do you guys think the lab FRQ will be on tomorrow? Is there a possibility it might be chromatography or calorimeter?</p>
<p>ChasingStarlight HAPPY BIRTHDAY</p>
<p>i hope it isnt on freezing point depression stuff or calorimetry, i swear</p>
<p>btw</p>
<hr>
<p>3 Cu(s) + 2 NO3−(aq) + 8 H+(aq) → 3 Cu2+(aq) + 2 NO(g) + 4 H2O(l) E ° = +0.62 V</p>
<p>ΔG° = − nF E ° = − (6)(96,500 C mol−1)(0.62 V)
= − 360,000 J mol−1 = − 360 kJ mol−1</p>
<p>How do you know that n is 6? n is like the moles of electrons</p>
<p>does a double bond count as 1 sigma AND 1 pi bond?</p>
<p>thank you!</p>
<p>What do you guys think the chances chromotography, carolimeter, freezing pt depression will be on it tomorrow?</p>
