<p>@ IAmCool ; What question was that? The pH? ( Can’t rememberrr. ): )</p>
<p>gonna curse CC if they dont be mercy on this freakin test…</p>
<p>i seriously have NEVER seen the questions like the Bohr ones in any books</p>
<p>The boiling point one on the phase change graph was B because it was at 1atm. </p>
<p>no, althought B was at 1 atm, it represented the change from solid -> liquid while d represented liquid-> gas (evaportation) and was also on the ! atm line.</p>
<p>■■■ 6 wrong</p>
<p>highest pH ( I HATE THIS)
bohr least E
ionization E
Na + H2O - - > Na+ + OH- + H2
H+ + CaCO3 produces:
NO2</p>
<p>@coup </p>
<p>it asked which compound had the HIGHEST pH
the answer choices were something like NaOH, HClO, H3PO4, etc. etc. at .1M concentration</p>
<p>i put H3PO4 because i thought lowest pH and H3PO4 was the strongest acid there…</p>
<p>IAMCOOL:</p>
<p>highest pH: most basic</p>
<p>^yeah i know, iwas telling coup the mistake i made haha</p>
<p>yea same. ■■■ ■■■ ■■■ ■■■ ■■■. </p>
<p>ok guys need some advice: i had to rush the last 10-15 questions or so. some were easy while others had more calculations. im pretty certain i got most of them right. i finsihed all but the last question. </p>
<p>now after seeing this thread i have gotten 3 wrong total so far. i left 3 blank. should i cancel?</p>
<p>^ And I’ll be beating myself up about that all week…</p>
<p>oh haha my bad :]</p>
<p>@ IAmCool ; … :[ Wow, well, feel better! I missed that too. Poop. I misread, too, and was thinking something along the lines of like highest [H+] concentration. ;____;</p>
<p>i ****ed up SO bad on this… i knew like everything and made so many dumb mistakes…</p>
<ol>
<li>ink question</li>
<li>T/F vaporization q</li>
<li>1 of the Bohr questions</li>
<li>density question blank</li>
<li>POSSIBLY the O2 left question (i put 2 L O2)</li>
<li>H20 9 g</li>
</ol>
<p>blank: density when adding NaCl question</p>
<p>6w 1 b… raw… 77</p>
<p>For people who thought they did well, what prep book did y’all use? Did it cover everything that showed up?</p>
<p>Was the bohr Ionization energy 0 (c)?</p>
<p>was separating water and ethyl alcohol –> evaporation?
for 9 grams of H20 … was one of the answers III. 11.2L of water… ? something like that–> it is H2O (l), not H2O (g). so wrong
isomers: first two
x203 –> B and He
Mendeleev Mendeleev was able to identify Gallium (True) b/c Aluminum and Gallium have same number of valence e- (True…?)
–> did not mention valence electron. mentioned total electron, so TF</p>
<p>md5hash </p>
<p>was it ur first time taking?</p>
<p>i hope they have a 5-7 point curve at least, which is what it should be.</p>
<p>at pete</p>
<p>-distillation for ethyl alcohol for sure
-isomers and 2 O3 is right
-Mendelev is right</p>
<p>Can ANYONE confirm the I. 9 g H20/ III. 11.2 L of water</p>
<p>I think it was [11.2 L H20] Because it was 9 g of H+ not 9 g of H… idr if it said STP :(</p>
<p>Does anyone remember the question about production of C02 with the delta H values and three different arrows?</p>
<p>I think i put 1 = 2 + 3 but that was a guess…</p>
<p>“for 9 grams of H20 … was one of the answers III. 11.2L of water… ? something like that”</p>
<p>i said I and III for that. i think I was how many moles of Hydrogen are produced, which was 9 times 2 /18 so 1 was correct.</p>
<p>also, what were the products were H+ Na+ and OH- or something like that…? or was it H2</p>
<p>answer
mentioned H20 liquid, not gas. so exclude 11.2 L
without reading carefully, can make mistake.</p>
