<p>I don’t know if this is right but for question 1, can you do the square root of [Mg^2+]/Ksp to find the [F-] for bii?</p>
<p>Here are the last 2:</p>

<p>No superstarlala, it does dissociate, but it is not a strong acid, strong base or soluble ionic compound. Only those 3 dissociate in the net ionic equation. I got tricked into doing that after I saw the little response underneath and i regret it, stupid mistakes everywhere.</p>
<p>Killerskullz You are wrong in delta H, as delta H is the difference between the start and the end, the transition state DOES NOT count. I made that mistake in an earlier practice test I took :/</p>
<p>@darkaeroga, not necessarily true. Say you mix HCl and Ag2CO3. The net ionic reaction would be 2H+ + CO3-2 -> H2O + CO2. In this situation, H2CO3 dissociates into H2O and CO2.</p>
<p>shoot… does 6e. have to have the hydrogens in the water molecule BOTH bonded to the only? I drew it sticking out with only one H attached</p>
<p>@darkaeroga, which question and which part?</p>
<p>Also, can we get guesses on scoring and how many points each question gets…?</p>
<p>do both of the Hs have to attach to the formalhyde on #6?</p>
<p>@killerskulz.</p>
<p>I disagree with your answer to 5e.</p>
<p>What you labeled as Delta H isn’t correct I don’t think.</p>
<p>Delta H is equal to the difference between the potential energy of the products minus potential energy of reactants. That isn’t what you indicated from what I can see.</p>
<p>Other than that—I seem to agree with your answers to everything. Nice job.</p>
<p>On that one you are correct, specific thigns such as NH4NO2, H2SO3, and H2CO3 (Among others) dissociates into their own compounds. But the general rule is the three I mentioned.</p>
<p>crappppp. Is that a full 2 pts off? Do you think I could possibly get 1 pt for H+ and HCO3-?</p>
<p>@APCalc, @darkaeroga, Yeah you’re right I missed that. I’ll change that.</p>
<p>that’s 2 points but don’t worry the equations are worth barey anything</p>
<p>@APCalc, @dark I updated that mistake, thanks for catching it :)</p>
<p>What about balancing? Is that also minus points because my products were wrong?</p>
<p>O.O</p>
<p>I just calculated my approximate score on AP Pass
I’m borderline 4 and 5
Oh Lord…CURVE, LORD, CURVE!!!</p>
<p>@randomandweird</p>
<p>I’m in the same exact situation as you! Now we wait… for like two months. Whyyyy</p>
<p>@superstarlala</p>
<p>They give you a point for correct balancing even if your equation is wrong
As long as your balancing is right</p>
<p>@Rememberance</p>
<p>2 WHOLE MONTHS

<p>UGH!</p>
