**OFFICIAL** AP Chemistry 2014 Thread

<p>@yoshithedino‌ Yeah, I realize that, but given that this is a new test, a 66% for a 5 is pretty likely. </p>

<p>Anyone have a good site for lab question prep? </p>

<p>Also, can someone explain to me what the FRQ can cover? Like is there certain topics for the long v short or something? </p>

<p>Thanks for the organic chem link, @Hawkace‌, but I thought that isn’t on the exam.</p>

<p>@collegetime18‌ I’m pretty sure that there are. This sucks. Why can’t we just have a document outlining what is on and not on the test? Are there reactions that we need to do?</p>

<p>@Hawkace I sure hope that will be the case, but looking at what they did with the AP Bio exam, I’m not too sure…
@jamesjunkers I’m pretty sure everything is fair game.</p>

<p><a href=“http://media.collegeboard.com/digitalServices/pdf/ap/IN120085263_ChemistryCED_Effective_Fall_2013_lkd.pdf”>http://media.collegeboard.com/digitalServices/pdf/ap/IN120085263_ChemistryCED_Effective_Fall_2013_lkd.pdf&lt;/a&gt; Starting on page 11, there is a fairly detailed outline of what exactly will be on the test. (It’s quite long)</p>

<p>@yoshithedino‌ To be quite honest, Bio is not as hard as Chem</p>

<p>I’ve heard that organic chem, assigning quantum numbers, and crystal structures aren’t on the exam</p>

<p>@jamesjunkers From the course description: “Section II of the exam will contain questions pertaining to experimental design, analysis of authentic lab data and observations to identify patterns or explain phenomena, creating or analyzing molecular views to explain observations, articulating and then translating between representations, and following a logical/analytical pathway to solve a problem” Basically section II puts emphasis on your ability to explain and justify why something is/isn’t happening using your knowledge of chemistry and the appropriate vocabulary (the question on the course description put a lot of emphasis on using the correct terminology when referring to a chemical phenomena) </p>

<p>also, does anyone know of any other practice tests online? I’ve taken two in my princeton review, the college board official one, and the barrons online. I just want to get as much practice in as I can before monday!</p>

<p>@collegetime18 Organic Chem isn’t directly tested but you may be asked to determine some properties of organic compound using you knowledge of chemistry.</p>

<p>From what I noticed the practice exam placed a whole lot of emphasis on equilibrium and partial pressures (Kp) and the fundaments of the concepts behind equations (such as relationship between density and pressure for gases, etc.) so be sure you’re familiar with the reasoning behind all the equations I think that’ll help shape a good and solid understanding of the concepts for the FRQs</p>

<p>By the way for all asking for the practice exam, a lot of us do not have it. My teacher shredded them before our eyes :frowning: it’s a whole legal/liability thing for teachers so some take that stuff pretty seriously </p>

<p>35.33 more hours</p>

<p>Has anyone find any similar practice tests? I already took the CB released one and I want some more practice that’s close to the real exam on Monday. </p>

<p>I’ve heard this new exam heavily emphasizes experiments, if so, what are some experiments that could appear on the test?
All I know are : PES, calorimetry, and titration</p>

<p>Gravimetric analysis is definitely a possibility as well </p>

<p>Can someone explain this AP Chemistry problem from the Course Description? The explanation provided doesn’t make a lot of sense.</p>

<p>K(s) + 1/2 Cl2(g --> KCl(s) ∆H° = −437 kJ/molrxn </p>

<p>The elements K and Cl react directly to form the compound KCl according to the equation above. Refer to the </p>

<p>information above and the table below to answer the questions that follow. </p>

<p>Process DH° (kJ/molrxn) </p>

<p>K(s) → K(g) v </p>

<p>K(g) → K+(g) + e− w </p>

<p>Cl2(g) → 2 Cl(g) x </p>

<p>Cl(g) + e− → Cl−(g) y </p>

<p>K+(g) + Cl−(g) → KCl(s) z</p>

<ol>
<li>What remains in the reaction vessel after equal </li>
</ol>

<p>masses of K(s) and Cl2(g) have reacted until </p>

<p>either one or both of the reactants have been </p>

<p>completely consumed? </p>

<p>(A) KCl only</p>

<p>(B) KCl and K only </p>

<p>© KCl and Cl2 only </p>

<p>(D) KCl, K, and Cl2</p>

<p>^ The one that’s not the limiting reactant?</p>
