<p>I think I did much better. I was a lot more confident and quick with the questions and left 5 blank (Last time I left 9). I predict a low 700s score, last time I got a 680.</p>
<p>it was easy</p>
<p>I didn't have a hard time with anything I knew (electrochemistry, stoichiometry, nuclear chemistry, yatta yatta yatta) which was fortunately most of it, but I did blank out on five of 'em, meaning my ceiling score is 800 by the most generous curve (but realistically I'll probably get more like 730).</p>
<p>i think it went ok, some of the practice tests I took were easier....</p>
<p>It was o.k. I wasn't sure about 2 of the lab questions on the first page (the separating two miscible, and forgot the other).</p>
<p>The separation one you were to use the funnel with a stopcock.</p>
<p>I took a complete guess, not sure what I put. I should've left it blank =</p>
<p>yea i'm glad I read over the equipment stuff right before the test, and yes taht's what I put murasaki</p>
<p>omg it was so hard...... i think i omited like 17 and probably got around another 15 wrong or something. how many t,t, ce's did you guys get? i got 4 i think.</p>
<p>Highest diffusion rate ch4
Alpha particle- for two of the answers
H-H is s-s
H-Cl is s-p
other one is sp3 sp3</p>
<p>How about lab equipment?
pipette for acid/base
dilute something to known concentration- use flask
which one to measure- cylinder</p>
<p>Limestone- acid</p>
<p>"Highest diffusion rate ch4

<p>Got all those. The sp3 one was C2H6. The alpha twice was in a row: e,e.</p>
<p>How about lab equipment?
pipette for acid/base

which one to measure- cylinder</p>
<p>other questions?
something about swirling- lab rules
something about 100g used to raise 6 C of 250 gram something
how about 200 gram to raise 500 gram? does temperature stay the same</p>
<p>sketchy answers
Ascetic?- ch3OH
NH3 for something
Not soluble in water - octane?</p>
<p>and also the graph PV vs P
is it a straight horizontal line</p>
<p>"something about swirling- lab rules
something about 100g used to raise 6 C of 250 gram something
how about 200 gram to raise 500 gram? does temperature stay the same</p>

Ascetic?- ch3OH
NH3 for something
Not soluble in water - octane?"</p>
<p>For swirling, I put to prevent the glass from contracting too fast.
For both temperature ones, I put that it went up by the same amount (t) and 6 degrees.
What was the acetic acid question?
I got NH3 for the one that asked about a .2M solution of Ca(NO3)2. What is the molarity of ______? I got .4M NO3.
What were the other choices for the octane one?</p>

Not soluble in water - octane?"</p>
<p>temperature stays the same because it's proportional
the acid from vinegar is ascetic
umm i put octane for the not soluble in water as well..</p>
<p>what else was there..</p>
<p>Linear molecular = CO2
Reaction with positive delta H (963 KJ I think) was endothermic.</p>
<p>Can you guys confirm the lab questions
How about lab equipment?
pipette for acid/base
dilute something to known concentration- use flask
which one to measure- cylinder</p>
<p>so for swirling, is it a? about some form of vaporization </p>
<p>SO CH3COOH is for both ascetic and vinegar?
not souble in water is octane
and what's the answer to the one that is something gas and is insolube in water? is it ch3oh</p>
<p>How about chemical property? Supports burning?
For pressure times volume vs pressure, the volume is a straight horinzontal line?</p>
<p>"How about chemical property? Supports burning?"
No, density. Burning is chemical. Denisty is physical.</p>
<p>I don't remember using the horizontal line...</p>
<p>then what's the graph for PV vs ideal gas P?
Is density one of the choices?
and for the swirling one, is it like vapor pressure or something(a)</p>
<p>I said density as well...i hope that's right</p>
