<p>I wrote TTCE for the isomer one, wasn’t sure though</p>
<p>After looking through this thread, it looks like I have 2 wrong so far. Stupid lab questions…I should have paid more attention in class.</p>
<p>yea for iron filings thats what i got. what about the nacl and h2o: distillation?</p>
<p>there was another balancing question with H2S</p>
<p>and question 101</p>
<p>^ that’s what I put. The others were off</p>
<p>yes distillation</p>
<p>Highest boiling point is NaAt right?
The iodine solid to gas is heat of sublimation?</p>
<p>yup, distillation
1 blank, 1 wrong so far</p>
<p>Bell Curves,</p>
<p>Highest boiling point is NaF, isn’t it? I asked my friend to check on the way back.</p>
<p>And yeah, heat of sublimation.</p>
<p>Highest was NaF, highest electronegativity difference = strongest bond</p>
<p>Now I’m really worrying. Was the energy needed to vaporize a solid heat of sublimation, or are you talking about the earlier question?</p>
<p>anbody remember the balancing question with H2S and the ideal gas question was 8.0 L
anybody remember the 1 mole question?? Was it 22.4 L??
Were there two questions where the answer was 22.4?</p>
<p>Was there answer that was oxygen famil?!! I don’t remember it at all???!!!</p>
<p>i think its the opposite because the smaller the ionic radius the stronger the crystal lattice so i think it was NaF and i put heat of combustion for the one where it went from solid to gas because that is the same as burning something in o2</p>
<p>I put NaF for the highest boiling point.</p>
<p>was oxygen family an answer?</p>
<p>[Enthalpy</a> of sublimation - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Enthalpy_of_sublimation]Enthalpy”>Enthalpy of sublimation - Wikipedia)</p>
<p>I’m pretty sure it was that for the last question of the test.</p>
<p>The nitrogen gas at 273K and 2atm was 11.2L right?</p>
<p>for the 1 mole of the ideal gas u just used the combined gas law so it was 44.8L</p>
<p>It was 11.2 because you doubled the pressure, so you halved the volume.</p>
<p>it said 1 mole which confused me a lot. So i put 22.4. I have no idea. I remember another question that also asked for the volume which I’m sure was 22.4.</p>
<p>anybody remeber the first T/F question 101.</p>
<p>yes, there was an answer Oxygen family</p>
<p>there was a question, asked for the volume of 1 mole of gas at 273K, but 2 atm. what was the answer? 11.2L right?</p>
