<p>isn’t solid C–> co2 be oxidation?
c0 to c4</p>
<p>i also got neutralization for acid + limestone (though it was more of a guess than anything…)</p>
<p>Win. okay for one t/f question:
press. goes up as volume decreases
speed increases as volume decreases (because they bumb around more)
is that T,T,CE
or was it TF???
ugh</p>
<p>I heard that the curve usually isn’t that generous - you need around a raw score of at least an 80 to get an 800.</p>
<p>Is pressure higher or lower as you move upward in our atmosphere?</p>
<p>i think i got that
was the formula for limeston like Ca(CO3)
i put neutralization</p>
<p>I think that c –> co2 was oxidation…</p>
<p>And pressure decrease as you move upwards in the atmosphere.</p>
<p>well it said solid–>gas
i put sublimation</p>
<p>The zinc 1.02x10^23 was 13 grams. One answer was k=1x10^50 the C + D question</p>
<p>sublimation is phase change, not a reaction
it would have to be solid C to gaseous C
or solid co2 to gaseous co2</p>
<p>maybe it is oxidation
yea i think so
crap
thats like two wrong so far</p>
<p>Wasn’t it 1.022 x 10^ 24 (not 23!) atoms? </p>
<p>That would be equal to two moles of products, and therefore 1 mole of Zn…or whatever reactant it was…</p>
<p>i got like 6.5…
i got the second one right though</p>
<p>The solid carbon to CO2 one is kinda poorly worded… It can’t be sublimation… but … if it’s oxidation (which I put)… it should say the carbon in CO2, but not as a whole.</p>
<p>What did u guys think for the one that’s:</p>
<p>H2 (g), O2 (g), HCl(g)?</p>
<p>H2 is definitely one, I don’t know if O2 is…</p>
<p>which one?
which question?</p>
<p>It was like the diagram and the question was asking which of the three gases could be collected through evaporation.</p>
<p>I think I put H2 and O2, since they both can be gases.</p>
<p>wait… first of all… r we supposed to talk about specific questions?</p>
<p>I thought O2 def was one but H2 wasn’t.</p>
<p>ohh i dont remember that
i think i skipped that
what about the T/F questions?</p>
<p>guys lets wait a few hours, ppl are still taking it and if they check this thread, it’ll decrease the curve and lower the scores of everyone here soo… does anyone know how long to wait?</p>
