<p>The instrument used for delivery of accurate volume.</p>
<p>Also, I used the round bottom thing when I Diluted Sulpuric acid, in lab last week</p>
<p>It’s certainly possible. Problem is, you never know what CB is thinking.</p>
<p>Is it just me, or I’m really scared. I thought, I did okay. But, the more I delve into this discussion, the more I realize I’m wrong :(</p>
<p>Does anyone remember the question that was discussed on the old thread? It was a true/false question.</p>
<p>The second part was: “BECAUSE all diatomic molecules are gases at STP.”
(That part was F, because of Br.)
What was the first part to that question?</p>
<p>The first part was N2, O2 and H2 are gases at 1atm, etc. which is true.</p>
<p>What about the
one need to measure the mass of the crucible and stuff more than once, etc. and the because part as well.</p>
<p>I think the 2007ers said it was t t ce for that one. ^</p>
<p>Biology was definitely more difficult than the Chem test… </p>
<p>For the diatomic question, I also remember putting false for the diatomic (I2 and Br2 are liquid at STP). And let’s be real, how many of our labs actually have a volumetric pipette that we can use all the time?</p>
<p>Does anyone remember the question about which equation had the least amount of entropy? I believe I said the equation that only had a solid as its product (as opposed to a gas).</p>
<p>Entropy was (g)–>(s)</p>
<p>Was that option a (b) or something?</p>
<p>It was either a b, c, or d, I think. And okay, that’s what I put. ^</p>
<p>The T/F question about All chlorine atoms being identical and having the same mass is false isnt it?
Or were they talking about chlorine atoms of a single isotope?</p>
<p>I skipped that one because I wasn’t 100% sure. What is the answer for the 50C with the curves? I put in acetone. Is it right?
Btw, I skipped 6 qs. Is it still possible for me to get a 800.</p>
<p>Yup, acetone.
Curves aren’t fixed. So, usually they range from 75-85 for extreme cases or even 81-85 for the easy cases. Can’t say really</p>
