June 2010: Chemistry

<p>not sure–that’s what my friend said. If you look at the chart, at the top left there was an infinity mark. He said that he got this question (probably slightly abridged) on a practice test</p>

<p>yeah i think its still infinity for ionization…</p>

<p>hm im hoping for a generous curve. test was fairly easy but laborous. also im pretty sure my proctor skimmed some time off</p>

<p>Was to infinity a choice?</p>

<p>yeah, we were wrong. THe Ionization energy is 13.6 eV, which would be D i believe, or infinity whatever.</p>

<p>lol ilovehelp, google it.</p>

<p>Do you remember the salt and water question?</p>

<p>higher boiling point, more mass?</p>

<p>i thought in the question, the choice was “the freezing point will stay the same” not lower</p>

<p>Explain your reasoning why it’s to infinity please. I still think it’s A.</p>

<p>jolly-</p>

<p>Saltwater would have higher density because of the present salt and lower freezing point.</p>

<p>You’re removing an electron, not promoting it to a higher energy level, so its infinity</p>

<p>crap your right. guys, im not doing too well. should i cancel?</p>

<p>i skipped 3 so i have a 17 question limit of things i can get wrong. i messed up on 1 true and false, and about 5-6 other questions listed so far. furthermore, im pretty sure on part C i got like 7 wrong since i was so pressed for time. should i keep it just in case i break 700?</p>

<p>but didn’t the actually choice say “same freezing point”</p>

<p>i agree it would be lower</p>

<p>jolly-
Was that question with saltwater one of those I, II, or III questions? My head kind of hurts from this.</p>

<p>umm i put the one going to infinity.
I think it was C/D.</p>

<p>Oh I’m so relieved that someone else got 1.42.
Someone told me it was 14.2 and I was really upset about that.</p>

<p>Do you guys remember the Q about the liquid that evaporates in room temperatureee?</p>

<p>for the sand/salt question wasn’t that using water than distilling it or something.
filtration cant work cause its… solid and solid?</p>

<p>@wang</p>

<p>yeah it wass a I, II, III</p>

<p>jele-</p>

<p>How is it 1.47? 14.7 is the answer that these guys in the thread agrees on.</p>

<p>It was most definitely 14.7, who remembers the question? I thought about it for a while.</p>

<p>jolly-
Then the choice did say lower freezing point. I remember thinking about it for a few minutes.</p>

<p>What about the least dangerous gas?</p>

<p>and is copper bonding covalent? no right?</p>
