<p>I got 100. And yes there was a graphing question for solubility.</p>
<p>Okay, couple of things.
I posted lots of questions with what I thought were presumably the answers on page 3 and pinki posted more on page 4, refer there before just asking your questions.</p>
<p>For the NH3 stronger base than water: water is amphoteric, it can act as a base or an acid. NH3 is a weak base, but a stronger base than water. Tux is way wrong in what he was saying. The strongest bases are alkali metal hydroxides and alkaline earth metal hydroxides.</p>
<p>For the buret question: A buret is 100% the most accurate way to measure any liquid no matter what you’re going to do with the liquid. Period. No debating this one.</p>
<p>
agreed. i’m pretty sure NH3 is a stronger base than water.</p>
<p>as for the polyermization question: thank God i guessed n-CHsomething.</p>
<p>What was the graphing question for solubility? (Can you please get specifics?)</p>
<p>And buret is the most accurate. I don’t think a graduated cylinder displays any decimals.</p>
<p>I’m upset about that question. I’m usually good with organic chem and so i kind of rushed that question. I just saw two hydrocarbons forming a bigger one and moved on.</p>
<p>Can anyone tell me the answer to all 3 graphs and the correct order?</p>
<ol>
<li>Time and Concentration</li>
<li>Pressure and Temperature</li>
<li>Volume and Temperature</li>
</ol>
<p>Same with me and organic chem. The question was something like which best displays the graph for the solubility of (something) in water whose solubility slowly but steadily increases as the temperature is raised. (obviously more formal wording)</p>
<p>Really? Where was it???</p>
<p>Can anyone tell me the answer to all 3 graphs and the correct order?</p>
<ol>
<li>Time and Concentration</li>
<li>Pressure and Temperature</li>
<li>Volume and Temperature</li>
</ol>
<p>

<p>This was on a list of strong acids and their conjugate bases. On that list, NH3 is one of the strongest bases, but H2O appears before it meaning that it is a weak base. I know I left out some information, but I am not wrong.</p>
<p>And for the buret vs. graduate cylinder, I put graduated cylinder. That can go either way. Both technically use the same mechanism for measuring. And there are different varieties of graduated cylinders which have some of the most miniscule units that you can measure for. And, if I remember correctly, they gave some sort of volume for this that was in mL and had decimals. You could measure that on either a buret or a graduated cylinder with the appropriate unit markings.</p>
<ol>
<li>curves up from (0,) and plateaus</li>
<li>straight line with positive slope</li>
<li>graph y = 1/x. It looks like the graph in the first quadrant.</li>
</ol>
<p>You are right, NH3 is one of the strongest CONJUGATE bases, not one of the strongest bases. Nevertheless it doesn’t matter because NH3 is a stronger base than water!! so woohoo TTCE</p>
<p>3 kind of looks like half a hyperbole right? It doesn’t touch the y or x axis right?</p>
<p>Wait… were those the three graph matching sections? and in that order? mine seemed different.</p>
<p>I think the graph matching is out of order. I don’t remember my sequence of answers going like that.</p>
<p>Plus one of them was pressure-volume I believe</p>
<p>Ya, the hyperbole one is P-V graph. So please someone tell me where on earth the solubility graphing question is? Thanks.</p>
<p>What solubility graphing question?</p>
<p>That’s what I’m asking. I don’t recall one.</p>
<p>I don’t know I really thought there was one…it could have been on a practice test though!!! but some one was like “yeah there was one” but i’m not sure… please some one answer if there was?!?</p>
<p>EDIT: ha NVM there wasn’t one. im not sure why someone agreed with me?!? i just found it in the practice test i was looking through in the car.</p>
