501

<p>Judging off what others have said, 77-85 would scale to a an 800. I feel that if this test is easier than most it might be 80-85 for an 800</p>

502

<p>the may 08 chem is the exact same</p>

503

<p>Statement 1: CO2 contributes to the greenhouse effect.
We know that this statement is TRUE.</p>

<p>Statement 2: When dissolved in water, the solution it forms is acidic.
We know that this statement is TRUE.</p>

<p>Whether Statement 2 is a correct explanation of Statement 1 is debatable. However, the general consensus is that it is NOT a Correct Explanation.</p>

<p>Monstor344, you are correct. Maybe we’re misremembering the question…</p>

504

<p>

</p>

<p>Wow. -_-
Does this happen often? (because if this does happen a lot I will prolly start reviewing Test Discussions before I take the real thing)</p>

505

<p>@monstor, I’m pretty sure it said acidic solution.</p>

506

<p>^it happened for us history too may 08 ush and chem were the same as june 09!</p>

507

<p>Do you guys remember this question about the properties of water? Is water most dense at 4 degrees Celsius? And can water act as a weak acid?</p>

508

<p>

</p>

<p>Both of those statements are true. Water is most dense at 4ºC and as an amphoteric species can act as a weak acid. Didn’t that question ask which property of water was incorrect? I feel like the answer may have been something about electrolytes, but I totally forget what the options were.</p>

509

<p>miriel, if i remember correctly, it was all of the following are properties of water EXCEPT:</p>

<p>and i think the answer was “it was a superconductor” or something</p>

<p>cuz it is definitely NOT a superconductor, it doesn’t even conduct electricity AT ALL if the water is distilled</p>

510

<p>Water is more dense at 4 degrees Celcius. (Remember that ice floats, it has lower density than liquid water)</p>

<p>Water is a weak acid and a weak base. Water is amphoteric (can act as acid or base).</p>

511

<p>I think the false statement was water being a strong electrolyte.</p>

512

<p>guys what was the first ttce, i tihnk i put t,f but i heard some ppl say it was t,t,ce. what was it?</p>

513

<p>Water is most dense at 4 degrees Celsius. I’m also pretty sure water can act as a weak acid because it can be an acid or a base.</p>

514

<p>Something about decrease in volume was increase in pressure - I think I put T/F too.</p>

515

<p>^ T F… average speed is not affected.</p>

516

<p>I think the general consensus on 101 was T,F</p>

517

<p>Do you guys remember what the first TTCE was? I’m trying to remember…</p>

518

<p>Was that the iron mesh one? I can’t remember in what order they were.</p>

519

<p>I think that the first part was: iron mesh rusts faster than a block of iron</p>

<p>and the second one: because the iron mesh has a higher surface area than a block of iron (equal volume)</p>

520

<p>Not was I was thinking, but I do remember that question. </p>

<p>Answer should be TTCE.</p>
