<p>went through the 2009 free response. Was pretty harsh, the readers expect you to apply concepts, not to just calculate stuff.</p>
<p>I’m unloading some of my resources here.</p>

<p>its an mcq so i can’t use the standard reduction potential…</p>
<p>ChickenOnRice - for the common oxidation one, I think you’re just supposed to know… I mean, at this point I guess you’ve seen it all so much in labs and all, that stuff kinda sticks.</p>
<p>Thanks coffeeandtea - I really should just call it done and study for Computer Science/my lin. alg final, but that looks like some quick and relatively easy last bits of info.</p>
<p>@Volta93: It’s sp. Each C in ethyne is bonded to an H and another C. Thus, it’s linear and displays sp hybridization.</p>
<p>This is sad but describe the process of solving this problem please. Have pity on me.
How many mL of 10.0M HCl are needed to prepare 500 mL of 2.00 M HCl?</p>
<p>Lol im not focusing on orgo that much , how about you guys?</p>
<p>lol runnerz that from 2008 right?</p>
<p>M1V1 = M2V2
10M(x)=(500ml)2.00M</p>
<p>^ Unless you’ve learned everything else, there won’t be more than a question concerning organic. </p>
<p>^^ Use M1V1 = M2V2</p>
<p>dam well o well…</p>
<p>i still need help with the nonpolar molecule with polar bonds. *** are polar bonds?</p>
<p>Can someone explain #6 on the 2008 MC?</p>
<p>oh that’s so easy =P thanks</p>
<p>ugh, i keep getting like 25-30 questions wrong on mc portion.
and by the time i get to the free response, i’m like dead .-.</p>
<p>i’m still confused on sigma and pi bonds. so let’s say an atom has one single bond, one double bond, and one nonbonded pair of electrons. would that be one sigma bond and one pi bond? are you supposed to disregard the nonbonded pair?</p>
<p>Last minute AP chem FRQ question
<a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>Supporting Students from Day One to Exam Day – AP Central | College Board;
<p>For 2005question 8(d)(ii), why is the reduction half reaction not Na+ + e- ->Na(s)? Could someone quickly explain please? Thanks.</p>
<p>Also, if I’ve been consistently gettin 80% correct on the FRQs, how much would you anticipate that I need to get right on the MCs for a 5?</p>
<p>ethene is sp , think of it as (-c-)</p>
<p><a href=“http://chemmybear.com/stuff.pdf[/url]”>http://chemmybear.com/stuff.pdf</a>
I’m confused with the “GASES THAT FORM” section. Can anyone explain it to me?</p>
<p>@feedback: there is always one sigma bond in each bond but can have as many pi bonds.</p>
<p>Just did the 2008. . . I got a raw of 54 (58-16 wrong answers).
That’s good, right? I mean, from this : <a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>Supporting Students from Day One to Exam Day – AP Central | College Board; I basically need to get the same thing for a 5 . . . so I need another ~70% on the free-response to get a 5?!</p>
<p>To Mordred, it would not be Na+ equation as it would have to be flipped to fit the reaction given.</p>
