<p>The vapor pressure was plain strange. The wording was grammatically incorrect so it really tripped me up. Now that I think of it, I think that was one of the ce.</p>
<p>The only CE is the one of ideal gases the mole ratio of blah blah</p>
<p>you use the water tube flipped beaker thing fot the separation of hcl and h2, correct?</p>
<p>And the 15 grams wasn’t even part of the true/false? I really think it was 2CE.</p>
<p>15 grams is a multiple choice was it 15 or 5? What is the other CE?</p>
<p>hannib is talking about the graph that showed solubility of a salt in water. It was part of the multiple choice. You add 20 G at 100 celsius, how much precipitates at 20 celcius? the solubility at 20 celcius is 5 g, so yeah it is 20-5=15.
So have we decided on the vapor pressure TTCE?</p>
<p>15 grams is correct</p>
<p>the second part of the vapor pressure/boiling point question was that the vapor pressure is less than or equal to the atmospheric pressure but shouldnt it only be equal to?</p>
<p>Just looked it up in Zumdahl 8th ed. The vapor pressure was a CE.</p>
<p>Sent from my iPhone.</p>
<p>The vapor pressure one was indeed grammatically ambiguous, yet it seemed like College board was going for something 
I don’t remember what I put.</p>
<p>No, the definition of boiling point is actually when the vapor pressure EQUALS atmospheric pressure. Pretty sure it’s CE, and so there were 2 TTCE’s in total</p>
<p>and the second statement of the vapor pressure/boiling point question said less than or equal to, so isnt that statement false?</p>
<p>I googled it and its TF in my opinion</p>
<p>I concur with Miami24. I say 2CE.</p>
<p>2 CE. When vapor pressure is less than or equal to BP the liquid is boiling. </p>
<p>I thought compared to barrons this test was a 4. Barrons is a 10. The last barrons test was very similar to this difficulty wise though.</p>
<p>Right, absolutely correct, but the “decreases with decreased temperature” was confusing. T T is “for sure”, CE? We need original wording</p>
<p>My bad i meant when atmospheric press is less than 1 atm liquids boil easier because vapor pressure is higher. Sorry lol</p>
<p>Exact wording was smth like the temperature at which liquid boils can be reduced by lowering the pressure above liquid</p>
<p>I think it’ll be difficult to get the actual original wording since it was so verbose and intricate (at least the second part).
But if anyone has it, by all means share!</p>
<p>How about the question asking about unpaired electrons in iron metal?</p>
<p>It was I and III</p>
