<p>I thought that the test was pretty good working from a Barron's book. However, one of the first few classification blocks were difficult, especially when predicting if a reaction would release an odor or not.</p>
<p>Release an odor? What question was this? ._.</p>
<p>Merp messed up on hydration and polymerization, but seems like just those two…
Anyone remember questions they thought were difficult?</p>
<p>400/300? anyone get that?</p>
<p>I think I got those correct. There was a list of compounds, and then you were supposed to match an effect to a reaction, like silver reacts with something to form a precipitate</p>
<p>Also…I couldnt finish the coefficient for o2…it was the one with c4h10</p>
<p>I also got 400/300.</p>
<p>Oh you mean the one with HCO3? (or was it H2CO3?)
thought that was gas bubbling</p>
<p>C2O? is the lowest</p>
<p>Can someone please clarify which reaction would produce an odor?</p>
<p>There were 5 answer choices and only two statements. I think the one with Ag was a precipitation reaction, and the other was an odor-producing reaction.</p>
<p>Do you remember the product(s)?
I’m pretty sure it was carbonic acid, which would be bubbling…</p>
<p>what was the answer to the modern atomic theory question? was it extranuclear electrons?</p>
<p>Indestructible atoms
We’ve developed nuclear fission, which breaks down atoms, so that’s wrong</p>
<p>I also put percipitate for the Ag one and indestructible atoms.</p>
<p>does anyone remember any T/F?
i know i totally messed up on that bc i got like 7 CE
and i got ALL trues for the right column…</p>
<p>how many TTCE’s did you guys get ?</p>
<p>very few. I got 2-4</p>
<p>do you remember which ones you got correct explanation on?</p>
<p>2C4H10 + 13O2 → 8O2 + 10H2O</p>
<p>combustion of butane 
I got a whole lot of CCE’s 
I’m probably taking this over again in May…</p>
<p>Ya I got 13 for the coefficient of O2, and I got 6 CEs, I’m pretty sure that’s about how many there were. And there was one lewis diagram of HCN, I got the picture with the triple bond.</p>
