<p>yes. the two that were not conjugate acid base pairs was H2O2 and H2o?</p>
<p>acetone was the answer with the graph. it asked which has a boiling point at 50C.??</p>
<p>I put buret for all three (4,5,6).</p>
<p>im thinkin thats really possible lol....</p>
<p>how bout for the other q's?</p>
<p>I got the buret for 4, 5, and 6 as well. Overall though, the test was easier than I though it would be.</p>
<p>****** im thinkin burette for all 3 seems pretty reasonable. CRAP.</p>
<p>how many u think can be missed for an 800?</p>
<p>dunkin wat about for the other questions? watd u get?</p>
<p>I got zinc, acetone, CaO, 766mmhg, 88. What did everyone get for the HF question(the last one)?</p>
<p>0.008? i think. or 0.08, but im leanin toward the former</p>
<p>0.008 for the HF one ..</p>
<p>can we get more answers on the 3 lab questions plz? all 3 burette's is possible but it seems unlikely that they would use the exact same answer 3x in a row..</p>
<p>are you guys completely sure it's all three buret? i put buret for the titration one ... and "n" is the principal quantum number right?</p>
<p>i agree with aa6590</p>
<p>im not sure, i put buret of titration, the dropper pipet (b) for the dilution, and graduated cylinder (d) for measuring accurate volume.</p>
<p>graduated cylinder is not the most accurate. it's volumetric flask.</p>
<p>really? hmm this is confusing
Volumetric</a> flask - Wikipedia, the free encyclopedia
i remember our teacher doing this sample lab for us with it.</p>
<p>oh and btw, any real general thoughts as to the test?
i thought it was mediocre in difficulty.
not as hard as june 2007, but still rather challenging.</p>
<p>curve predictions anybody?</p>
<p>A - pippette
D - the cylindrical thing
A - pippette</p>
<p>definitedly not buretter for all three...a burette is just used for titrating an acid with a base (which I btw, did just 2 days back in my high schools lab)..1 answer is measuring cylinder, the test tube like thing with markings on it...not so sure about the third</p>
<p>no, a burette was definitely used for titration.</p>
<p>the only one i got wrong (which i know of so far) was the dropper pipet. We don't have that apparatus in our school so i didn't know what it was so I chose the buret. </p>
<p>I thought n=0 was the principal quantum number (not "n") so i was a bit confused, so i put the answer with shape or position of the orbitals.</p>
<p>EDIT: The two i'm 100% sure are correct are</p>
<ol>
<li>buret for neutralization/titration</li>
<li>volumetric flask for measuring to a known volume (hence the name "volumetric"-it only measures 1 volume).</li>
</ol>
