<p>I’m pretty sure I got a 3 on this. If not dang…</p>
<p>I’m so confused. I had Form O, but those aren’t the free response that I had on my exam.</p>
<p>thank you so much @hypnotoad</p>
<p>For 3D, does the cell potential stay the same as concentration is halved? I remember an equation comparing concentration to cell potential, but people have been saying the potential stays the same.</p>
<p>@ProvocativePanda Cell potential is always the same regardless of concentrations.</p>
<p>Ok Thank gooodddd I put that but one of my friends said it was unaffected</p>
<p>@ProvocativePanda: The Nernst Equation tells us that as concentrations are varied, the cell potential can vary. However, the value for concentration of each half cell must be different from each other for it to affect the voltage. Since in this case, the molarities were the same, it doesn’t affect the Q value, which means it doesn’t affect the voltage.</p>
<p>What are the total points of each question? </p>
<p>I think 10 for long, and 4 for ahort</p>
<p>@graceann you are right. I’m sorry for that. It puts them on the top 5%</p>
<p>So…is the curve predetermined?
My teacher said that wouldn’t be fair because we were their trial group for the new format which shouldn’t give us any less of an opportunity to get a five as last years clear.
Then again, he also said that there would be no hybridization on the exam but look how that turned out.
Guess I better start drug dealing. </p>
<p>@Aaly222 it was predetermined and your teacher</p>
<p>@LycanAlpha I’m sorry but I honestly don’t understand what you are trying to say lol</p>
<p>@Aaly222 I was saying that the curve was, in fact, predetermined by collegeboard. The teacher but was an accident.</p>
<p>*bit</p>
<p>@Aaly222 but in reply to the claim that it would be more fair, the fact of the matter is that it will be a more accurate bell curve, not more or less fair per say.</p>
<p>Guys would it alright if I suggest we make a google doc with the multiple choice answers as well? like people cans tart contributing questions they remember? </p>
<p>@jy2013 It’s a good idea in theory, but it may be illegal.</p>
<p>Where are you getting the idea that the curve is predetermined?</p>
<p>@Hypnotoad Sorry, quick question. The CaCO3(s) —> CaO(s) and CO2. Kp = (CO2), but when you add more CO2 into the system and force the reaction towards the reactants is it possible for the CaCO3 to run out before reestablish 1.04 atm? </p>
