<p>O2 and O3 are allotropes</p>
<p>for finding the vandium and oxygen formula, it was VO2.<br>
Anyone remember the first part of the test very well (questions 1-15 about)?</p>
<p>Not particularly. I agree with making a list of answers…who isn’t taking an AP exam and has time? :P</p>
<p>cardboard + magnet (some powder and Fe)
the distiller and condenser (i think was nacl but i cant remember)
The two colored inks
And there was one other one for the first section…</p>
<p>hey was May 2008 Chem test harder than other Chem tests??? or was it easier or similar to other ones???/</p>
<p>THAT THING WAS HARDDDD</p>
<p>Which one has the highest melting point.
A. CsF
B. CsCl
C. CsBr
D. CsI
E. CsAt</p>
<p>HOW DO YOU KNOW THEIR MP??? ***</p>
<p>What was the answer to
T/F HCl + AgNO3 forms AgCl
T/F HCl is a strong acid</p>
<p>HOW DO YOU FIGURE OUT WHAT IT FORMS ? I FORGOT THE METHOD ..***</p>
<p>AND HOW DO YOU KNOW IF ITS A STRONG ACID?</p>
<p>You memorize the strong acids: Hbr, HI, HCl, HClO4, H2SO4, HNO3
You have to memorize the solubility rules as well for that question. I believe I put down T/T</p>
<p>And CsF has the highest melting point because it’s hardest to break the ionic bonds.</p>
<p>How did you know that it was the hardest to break though?</p>
<p>F is the most electronegative element.</p>
<p>What about ::</p>
<p>what did you guys get for the question that asks about what concentrations will be the greatest when Na2SO4 is in water?</p>
<p>would it be Na+ and SO4 2- ?</p>
<hr>
<p>How do you do that question? I completely forgot</p>
<p>well you know that Na is a +1 ion pretty much always and SO4 is -2 so when you break it Na2SO4 you know the highest concentrations will be of the most common ions: Na+ and SO4 -2</p>
<p>The other choices they have don’t really occur.</p>
<p>Wait</p>
<p>the highest concentrations will be of the most common ions</p>
<p>But the most common ion is SO4 -2 since it has the most</p>
<p>well the highest concentration is of Na+ because there are two mols for ever mol of the compound. However, that is irrelevant because Na+ and SO4 2- were in one answer. (Correct me if im wrong)</p>
<p>Yep, they both were 
</p>
<p>The other ones were like Na2+, Na2, SO3, etc etc</p>
<p>anyone remember the questions on the graph (there were like 2)</p>
<p>Someone make a list…as long as we’re taking our time to do this…</p>
<p>you make the list!!! i’m tired of making all the god damn lists!!!</p>
<p>what lists? You’ve never posted b4 this thread lmao!</p>
<p>I thought it was V2O5…</p>
<p>mole ratio was 1:2</p>
