<p>overall easy or hard?</p>
<p>What do you think curve should be like?</p>
<p>78/79 = 800</p>
<p>How is CO3 a strong base? KOH is a strong base…</p>
<p>I said 1M HCl for the most heat I think.</p>
<p>Also for the bonds,
NH3 - lone pair on the N
CO - has a triple bond
forgot what i put as the one with the double bond…I just drew them out.</p>
<p>this test was soo hard…i’m in ap chem…and a lot of the stuff was nothing i saw on practice tests…tear…</p>
<p>Ahh yeah NH3 was lone pair. It said one and only one lone pair, I remember, haha.</p>
<p>CO2 had the double bond</p>
<p>Yeah it was CO2.</p>
<p>Test was hard compared to the practice test I looked over.</p>
<p>im a senior and i took the chem sat ii when i was a sophomore. this test was much harder. ( igot 750 last time)</p>
<p>…failed this.</p>
<p>Oh well, it should have a nice curve?</p>
<p>Was the answer for the excited electrons something with “quanta”?</p>
<p>The TTCe for this test was challenging, but I’m feeling confident now.</p>
<p>I said light. But I wasn’t sure on that one.</p>
<p>Co3 strong base
reason: Hco3 weak acid - Co3 strong base due to being its conjugate</p>
<p>NH3 single bond, correct me if wrong</p>
<p>heat one was 1m Hcl it was a trick. it was a simple titration solution i was luckily able to see it 100 *1 = 100x
so x equal 1m
the only logical choice was 1 m HCl</p>
<p>this might have been the hardest chem test ever administered in Subject test history</p>
<p>Correct me if i’m not answering this correctly but i dont remember the question all too well.</p>
<p>Co3- is a strong, weak base.</p>
<p>The only strong, full dissociation bases, are those with hydroxide(OH-) right?</p>
<p>the most accurate solution was buret</p>
<p>I just thought which one would bring it to completion :P. 1M strong base requires 1M strong acid. = 1M HCl</p>
<p>NH3 is a single bond between the N and H but it has a single lone pair on the N making it a pyramidal. (1+1+1+5=8 electrons in total, therefore, 3 single bonds + 1 lone pair = 8 electrons)</p>
<p>(Draw it out and count the electrons).</p>
<p>Would OH- be the strongest Bronsted-Lowry Base? I mean It’s the best proton acceptor.</p>
<p>Oh and what’s the curve looking like this year for a 800? How many can you miss considering you left 0 blank.</p>
<p>well the thing is that Co3- is a moderate strong base wikipedia</p>
<p>for OH- to be a STRONG base it must have a alkali metal or alkali earth metal bonded with it, which it did not. The OH- was meant to be a trick.
I’m 100% sure it was Co3-</p>
