<p>shoot abaout the polymerization one. and my GC arae +/- .5 while the burets are +/- .1? so isn’t that still more precise? Couldn’t you dispense the thing you were mesuring more precisely this way?</p>
<p>Did it say anything about dispensing?? Haha, I don’t think this question will ever be answered.</p>
<p>Lol. So shadowrider, once you put something in a graduated cylinder, it can never come out? And it’s physically impossible for a buret to ever gain liquid? once you use all the titrating fluid, you have to throw it away?</p>
<p>I still think it’s buret. It’s more precise and there’s no reason why you can’t use a buret to measure a liquid.</p>
<p>I am in agreement. Did anyone get XC2H3O2 for something, although I don’t remember what it was. i think it was like least likely to form</p>
<p>^ What is this question you guys keep talking about?! I am so confused.</p>
<p>Yeah it was. Because the M had to have a charge of 2+ (it was with SO4, which has a charge of 2-) while acetic acid is 1-. Wouldn’t work.</p>
<p>i was pretty sure you dont use a buret to measure liquids… think about it, have you ever used a buret JUST to measure liquids?</p>
<p>Yes. My chem teacher does when she does demonstrations when its actually important she has the exact right amount of the liquid. Also, when we do titrations we measure BOTH acid and base with a buret, in order to get accurate measurements for the thing we are titrating as well as what we are using to titrate.</p>
<p>ok for the CO3 2-one, since it has a 2- charge, wouldnt it be better at oxidizing?</p>
<p>More thoughts on Buret vs. Graduated Cylinder? </p>
<p>Thoughts about Polymerization being E? Was it really? LoL. I checked Wiki and C could represent a condensation polymerization reaction. </p>
<p>“Condensation polymerization occurs when monomers bond together through condensation reactions. Typically these reactions can be achieved through reacting molecules incorporating alcohol, amine or carboxylic acid (or other carboxyl derivative) functional groups”</p>
<p>Yeah but it said “in this reaction”. It doesn’t oxidize anything in that reaction because it’s not an oxidation reduction reaction</p>
<p>I don’t know where people are getting the idea that NH3 is not a base. It is actually one of the strongest bases. The strongest base is NH2-, then OH0, then CN-, and then NH3. After that, there are 15 or so more that have been determined to be weaker bases. Water appears more than half way down the list; it is a weak base. This is straight from my chemistry textbook.</p>
<p>wait… i was looking at the post before…
'“Adding NaCl to a saturated solution, no change in concentration = T”
?? what??</p>
<p>Well it’s saturated…</p>
<p>I’ve used a buret for just measuring liquids. I used it at Chem Olympics like two or three weeks ago for that. It’s very accurate. It’s also very very good for spreading substances throughout a liquid.</p>
<p>Adding NaCl to the a saturated solution would just make the NaCl float to the bottom. So no change in concentration…</p>
<p>Or at least that’s what I thought</p>
<p>polymerization: the process of combining several monomers to form one large polymer.</p>
<p>polymer: made up of repeating, identical, units called monomers.</p>
<p>I put C to but I think its wrong. I fell for the “lots of C’s,H’s, and O’s!!!$#<em>&</em>(#@ must be polymerization!!” trap. but it wasn’t repeated like E was.</p>
<p>Jinxed, you mean sink to the bottom? Haha :]</p>
<p>Was there one about graphing the solubility for something as temperature increased? I think i’m going crazy.</p>
<p>And did anyone get 100 on that one about acid of pH 4 and acid of pH 2 or something?</p>
