<p>I remember getting two TTCE’s towards in a row towards the end of the T/F section. Anyone else?</p>
<p>I think I got a total of 3 or 4 TTCEs… I’m not quite sure though.
Is “all molecules are at the same speed at any instant” the thing that was NOT true of kinetic molecular theory o-O?</p>
<p>^@kikuhana</p>
<p>I hope so because that’s what I said.</p>
<p>3.5 M anyone, because the volume is doubled?</p>
<p>did anyone else get something like .0117 for one of the questions?</p>
<p>^ yep i got 0.117 i think</p>
<p>What did the 0.117 question ask?</p>
<p>-oblivi0n: I think I got 2.75 M for that question… but I wouldn’t trust me, since I was rushing insanely hard and didn’t re-check that problem T.T</p>
<p>^I got 0.117 too, lol.</p>
<p>there was an exercise with a bunch of electrode potentials. with ni, h, and i think au. which one did you choose? i don’t remember the question</p>
<p>I also got 2.75 and .117. I’m very confident in those answers. According to Kinetic Molecular theory, temperature is AVERAGE kinetic energy of the molecules, so no, not all were at the same speed. Also, I picked Au3+. Since oxidizing agents get reduced, and Au3+ was 1.5 for the reduction reaction, it was easily Au3+.</p>
<p>I recall getting 3 T T CE.</p>
<p>Hopefully I got at least 780. I wanted to take in July when it was fresh from AP Chem, but I couldn’t, so we’ll see how it goes.</p>
<p>yep
i got 2.75 .117 and Au3+ also</p>
<p>hey, hahalolk, which one was the right answer on the molecular kinetic theory question?</p>
<p>^I don’t remember. I just remember specifically that it wasn’t that they all have the same speed. If you could remind me of the choices I could answer it. And the question as well; I forgot what it was asking for.</p>
<p>the one with all atoms have the same speed is the wrong theory. It’s obvious that not all atoms will have the same speed. They will, however have the same average speed.
Ok, my question.
Was the PBbr3 the unstable molecul because pb3+ doesnt exist
Was the atom the neutral particle</p>
<p>Na3po4 is basic in solution because Po4 attracts H+ ions and NaOH will exist. H3po4 is a very insoluble acid so and NaOh is soluble. Therefore the solutikon will be basic. Is it true that the concentration of products and reactants will not change at equilibrium. I wasn’t sure.</p>
<p>Yes, the atom was neutral. Cations, anions, electrons, and protons all have charges. An atom has no charge.</p>
<p>Na3PO4 was basic in solution. And it is true that the concentration of products and reactants will not change at equilibrium, because the forward rate equals the reverse rate.</p>
<p>wow, I got one wrong. darn it. So was the PbBr3 unstable because Pb3+ doesn’t exist.</p>
<p>I got about 2 or 3 TTCE</p>
<p>There were two TTCE i got in the end. I recalled them being easy. I think one of them was about Temperature and Pressure doubling.</p>
<p>also, was I suppose to read the meniscus at the buret</p>
