<p>which questions do u think will be taken out because they are unfair</p>
<p>Does anyone know the answer to the question which had “ground state,” “valence electrons” in the question?</p>
<p>They take questions out b/c they’re unfair? Sorry, this is my first SAT</p>
<p>Guys for the one question with hg+2 becoming hg and a solid metal becoming an aqeuous ion, it asked what reaction it was. Was it electron transfer reaction? </p>
<p>Two ttce questions I remember were the one on hydrocarbon composition and other was the last on acetic acid and h2so4 (I think). For the hydrocarbon I said FT and the last one on the acids I said TF I think. Anyone agree?</p>
<p>yeah thats why it takes almost 3 weeks to get back your scores! if like the people within the top 10 percent don’t get it right and like mostly everyone gets it wrong, then they scrap the question because it wasn’t one that showed the diversity of people</p>
<p>Any guesses on curve?</p>
<p>I need explanation so I won’t commit the same mistakes next time…
From the list:
- “No visible change = Na2SO4 and NaOH.” Why? Is it because its a double replacement and it basically forms the same thing?
- “Electrons release energy in packets called quanta.” I dont remember reading this from my barron’s book. But I might have missed it. Anyone?
- “Exothermic when K+ and Cl- crystallizes out of solution” I thought KCL dissolves or dissociates completely?</p>

I chose electron transfer. Almost chose proton transfer during the test though but I looked it up just now and saw that acid-base reactions are the kinds that transfer protons</p>
<p>Darn, for the copper wire i put “It turns black” as something that doesn’t happen. >.></p>
<p>Which was the semiconducting metalloid and which was the major component of brass?</p>
<p>Anyone for the two ttce questions I posted above, did they get the same thing?</p>
<p>I got FT for the hydrocarbon question. And the acetic acid and HCl one I said TF. True that HCl dissociates more, and F that Carbon has a higher electronegativity than Cl.</p>
<p>which choice was the complex ion?</p>
<p>@xazndudex i’m not sure… but i think my answer was the one w/ NH3</p>
<p>btw everybody, one of the last questions was weird: some alkaline earth metal combines with N2, what is the product? i think it was Magnesium as the metal, so i got Mg3N2</p>
<p>for Cr3+ thing, how many electron moles were transferred? I put 3… but IM probably wrong</p>
<p>@nirvana1234 i got 3 as well</p>
<p>I got 3 moles too</p>
<p>@squashaddict YAY!!! You made my day! haha, but I think I got 5-10 wrong so hopefully 770+…</p>
<p>NH3 is one of the most common components of complex ions, so I put that.</p>
<p>Yes it was 3. It went from a 3+ oxidation number to a 6+</p>
<p>So far I think I’m between 0-3 wrong. Hopefully I can get an 800, or at least a 790…</p>
<p>so I took both physics and chem today and I don’t get why chem’s curve is so much harder when their percentile ranks are so similar (91% and 90%) and they’re comparable in difficultly</p>
