<p>and how many CEs did you guys have? I think I had four and I skipped one of those Qs</p>
<p>seperate alcohol and water is distillation
salt and water is evaporation</p>
<p>I had 5 CEs....:/</p>
<p>j-dom, I was able to balance EVERY equation successfully and I am pretty sure that I did them all right.</p>
<p>i had a lot in the second row....one after the other...</p>
<p>One of the equations I had trouble with ended up being 1 1 1 4....the NH4Cr one...but yeah, I balanced them all too.</p>
<p>tapedDuck, i probably missed something then. that's unfortunate. should i cancel if i skipped 6 and probably missed some?</p>
<p>I had 3 CE's in a row in the second column... and in the first i had one T T but not CE, and one CE. I think.</p>
<p>I had a lot of T, F. and yeah, I had one that was TT and not CE, and one CE.</p>
<p>^ me too..........</p>
<p>delta 1 = (delta2 + delta 3)</p>
<p>oxidation state of __... was +5..</p>
<p>acetic acid is a stronger acid that HCl because it has more H+ than HCl. (that was a Q .. or something like that.)</p>
<p>TF Mendeleev was able to predict the properties of Ga, but Ga does not have the same number of electrons as Al.</p>
<p>separate methynol alcohol and water: distillation</p>
<p>separate sugar and sand, it was water treatment followed by filtration;</p>
<p>paper chromatography (choice D);</p>
<p>Critical point on the phase chart ___?</p>
<p>Least harmful gas to humans CO2</p>
<p>the Bunsen burner would not have helped. Other options were erlenmyer flask, buret, indicator, analytical balance</p>
<p>N2 has the triple covalent bond</p>
<p>the TFCE questions: Water is polar - Water is linear.</p>
<p>there was something with a 180 degree bond angle too. </p>
<p>And a 'square planar' thing, with a methane (CH4) molecule.</p>
<p>In a closed vessle, 3 moles of ...Gas A.... and 2 moles of "Gas B", total pressure = 1.5 . whats the partial pressure of Gas A?
For the closed vessel one, what did you get?? 1.0?</p>
<p>0.025 Moles was an answer.</p>
<p>which of the following has the smallest radius....</p>
<p>(a) F-
(b) O 2-
(c) N 3-
(d) NA +
(e) MG +2</p>
<p>which of the following is the least harmful in the atmosphere to humans...</p>
<p>(a) CO2
(b) NO2
(c) NH4
(d) SO4</p>
<p>which exists as a ionic solid at room temp?
CaO, or _____.... (I chose the one I can't remember)</p>
<p>isomers: I and II</p>
<p>Na+ H2O -- > NaO + H2 (g)</p>
<p>1L of O2 remains.</p>
<p>Hmmtrhytrjhytj</p>
<p>yeah, that was a Q. Yeah, you're right too-- HCl is a strong acid, and acetic acid is weak.</p>
<p>it wasnt HCl it said acetic acid is a stronger acid than H2SO4..... i put FT</p>
<p>i got .9 for the partial pressure one.</p>
<p>yea i put FT as well!! and isn't water bent (not linear)?</p>
<p>yeah i got 0.9 for the partial pressure one too</p>
<p>Yes water is bent.</p>
<p>wait... you can have a CE when its not TT???</p>
<p>no.... but you can have TT and no CE</p>
