<p>Hope this helps. Did this very quickly so there might be a couple of mistakes. Feel free to comment if you think you see a problem.</p>

<p>@hypnotoad107, honey, you are soooooooooo friggin amazing.</p>
<p>Welp, looks like I really did fail everything on this test. Oh well. Good job hypnotoad!</p>
<p>My pleasure :)</p>
<p>Yaay ty ty</p>
<p>@renoverchat. Seems these FRQs were tough for a lot of people. I actually think the alternate form might have been a bit easier this year. Electrochem and Organic are both troublesome for students as a general rule (probably due to time constraints), and to see them both on the FRQ to this degree is pretty rare. Think the curve for this form might be a bit more generous than the curve for the alternate form. I will say, however, I thought the Equilibrium question was pretty straight forward.</p>
<p>Surprisingly I got the electrochem, but for the life of me couldn’t remember the equation for the solubility constant. If only there could have been something with an ice box…</p>
<p>As a general note, I think any student in AP physics and AP Chem might have done better with the electro chem, thoughts?</p>
<p>Shouldn’t number 2a have a ratio of Aluminum formed to electrons transferred as 4 mol Al: 6 moles electrons? According to the balanced equation given?</p>
<p>I’m not really good with Chem, but for the first one, are you sure it isn’t</p>
<p>MgF2 + H2O -> MgO + 2HF</p>
<p>? Because it says “chemical equation”, not net ionic</p>
<p>I apologize in advance if this is a dumb question</p>
<p>How about an answer key to the ap physics B free response? haha very good job on the chem ones though</p>
