<p>Hey there! Can someone explain bond order to me? I looked up the formula on google and got .5 X (bonding elections- antibonding electrons). *** is an ANTIBONDING electron?</p>

562

<p>Guys, how come they put a solid in the equilibrium expression in 1v?</p>

<p>Come on, AP CENTRAL!!</p>

</p>

<p>Bond order is just the number of bonds, like for H2, it is 1 (single bond), O2 is a second order (double bond), N2 is a triple bond, so order is 3</p>

<p>Thank you =)</p>

<p>Collegeboard is down, so use this site for practice FRQ</p>

567

<p>lemone: they showed a general equation of equilibrium. If you read the question, there’s water, making the compound aqueous. And, as you know, we dont include water in Ka</p>

568

<p>lemone… you are a life saver…</p>

569

<p>INTERNATIONAL FRQS WAS SO HARD! well…at least the first question was, because I did NOT expect it…lol part B was easy…</p>

<p>What’s the cutoff for a 5?</p>

570

<p>oceanangel:
on a scale of 1-10, 1 being super easy and 10 being ohh ****, how would you rate the MC?
like compared to the 2002 or 2008 ones if you’ve taken them :)</p>

571

<p>MCs weren’t that bad…I’ve taken previous years’ papers before but I don’t actually know which years they were from haha but I would say about…5 for me. It was about the same level of difficulty from the papers I’ve done before~ I’m just really worried about my FRQs haha</p>

572

<p>haha that’s what I’m worried about too! I can only get credit if I get a 5 on this test, and that’s not looking really likely especially since I suck at Ksp/Kp/Ksomething and that integrated rate law thing. heh.</p>

573

<p>^ did you take the test yet? >.<</p>

574

<p>PMed you :)</p>

575

<p>general question…
do we lose points on the FRQs if we write a wrong answer? (because I know we lose points if we put a wrong answer for the multiple choice…)</p>

576

<p>No there is no pt. deduction for incorrect answers. Actually, many times points can be gained even when you have wrong answers (assuming you set up your problem correctly). </p>

<p>Point blank, try to come to the correct answer. But if you cannot, put down the equation and set up your values. You’ll at the least get half the points possible for that question.</p>

577

<p>wait…so there are point deductions for wrong answers on the multiple choice only
right?</p>

578

<p>Yes. only for MC</p>

<p>@Everyone: GOOD LUCK! HOPEFULLY YOU WILL ALL DESTROY THE CHEM EXAM. Cya after the test. ;)</p>

579

<p>omgosh i am so screwed for this!
do you think the make-up ap exam will be harder than todays?</p>

580

<p>Well, I’m going off to take the test in less than 30 minutes…thanks for the help of everyone on this board. Best of luck to everyone, and here’s something to lighten the mood.</p>

<p>A group of organic molecules was having a party when a group of robbers broke into the room and stole all of the guest’s joules. A tall, strong man, armed with a machine gun came into the room and killed the robbers one by one. The guests were very grateful to this man, and they wanted to know …who he was. He replied: My name is BOND, Covalent Bond.</p>
