Official 2010 AP Chemistry Discussion

<p>we started equilibrium a week ago and starting acids/bases equil.</p>

<p>via: You’re definitely a bit behind.</p>

<p>really? all we have left is redox/electrochem and nuclear chem</p>

<p>Oh, I wasn’t aware that you have already completed thermochemistry. A bit strange that you did thermochem before equilibrium.</p>

<p>Really? We did thermo REALLY early in the year. Like September. Adding it to electrochem, for us at least, was just review.</p>

<p>We’ve been reviewing, right now we’re on a review of bonds and hybridization! Has anyone taken the Chem Olympiad local test yet? Mine’s this Saturday and I’m pumped!</p>

<p>What is the common trend among scores on the MC and FRQ is MC usually higher?</p>

<p>We did thermodynamics. Is that related?</p>

<p>We’re doing Solutions right now. Just finished Electro too. I’m just worried because we have our practice exam the Friday we get back from Spring Break which is in 3 weeks 3 days, and I am really worried because she’s counting the practice exam twice as a test grade. Of course I will be studying over Spring Break wherever I go…but it’s so sad that the teachers count it as a test grade and if you do bad…woops my grade just went in the toilet…</p>

<p>@NewAccount: yeah we did thermo just a little before, i guess thats just how my teacher decided to do it. wow, i was freaking out because i do NOT want to be behind in an AP as difficult as chem, whew…</p>

<p>I’m in Bonding… Still a long haul ahead.</p>

<p>I’m taking a non-AP accelerated chemistry class that’s probably harder than many AP chemistry classes (less than 5 people got A’s last semester). We’re on solutions now, and I’m going to start studying the stuff that we haven’t covered yet sometime.</p>

<p>We just finished electrochem, and are about to start thermodynamics. We did solutions earlier. It’s interesting how much variation there is in the order of topics.</p>

<p>we have 4 chapters to cover… a bit late
and btw i also take ap phys b class and we are only halfway through XP</p>

<p>Anyone know where I can find practice MC Q’s?</p>

<p>We are doing acid/bases. Anyone know the importance of sig figs on the Exam?</p>

<p>Apparently you can be off by one sig fig and it will still count.</p>

<p>So if your sig figs are off by more than 1 will they give you partial credit or no credit?</p>

<p>That’s what I’ve heard. I assume the answer will be considered wrong, but the work will still be fine.</p>

<p>Hmm I see some discrepancy, though, because my AP Chem teacher attended an international teacher conference and the participants said, for Chemistry, significant figures do not matter unless you give at least 3 places…? Idk.</p>

<p>That’s incorrect. ^</p>

<p>There is room for 1 sig fig error.</p>
