<p>what about the TTCE question on pure water being a bad conductor of electricity and it’s small Kw value? </p>
<p>I got T, T, CE for that one. You need ions to conduct electricity.</p>
<p>@Suchwowmuchcool thanks</p>
<p>how about for the one asking to calculate the molar heat of fusion of H20?</p>
<p>Ok good! 
Also what about the one with CO3- and something else (i don’t remember what) and it was asking whether it will produce a gas, precipitate, colored solution, etc? </p>
<p>@ak1998 I forget that question.</p>
<p>Do you guys remember the tools you needed to find specific heat of something? Did you include balance? I thought balance was what you used to weigh mass so I included all three.</p>
<p>@2015er I said gas because if you put H+ and co3 2- together you get h2co3 which decomposes to h2 and h20, making a gas</p>
<p>And the one below it was precipitation I believe, right? @Suchwowmuchcool </p>
<p>@Suchwowmuchcool I said that you need all three for the specific heat question because of q = mc∆t and the balance would help you get the mass…not sure if that’s right though</p>
<p>@2015er Alright, I wasn’t exactly sure what a balance was, lucky guess for me lol</p>
<p>@2015er I forget the one below it</p>
<p>@ak1998 I multiplied it by the molar mass (18 g?)</p>
<p>Correction: h2c03 -> h20 + co2</p>
<p>I said all three for the one about calorimeter also</p>
<p>also, for like 2 of the balancing questions i got 3 as the coefficient…does that sound familiar to anyone?</p>
<p>@blubrrybanana22 I remember that one now, yeah, I multiplied as well</p>
<p>All the TF’s I remember, with my answers in parentheses:</p>
<p>-water worse base than NH3 b/c NH3 accepts protons better (TTCE)
- metals are good conductors because they contain positive and negative ions (TTCE)
- water bad conductor at room temperature b/c KW = 10^-14 which is bad (TTCE)
- F2 is a gas at room temperature b/c it has weak imfs (TTCE)</p>
<p>Others:
- which is the best for measuring 23.15 mL (buret)
-For the sudden jump in PV, I’m going to file a complaint because I thought that the question was ambiguous, since we didn’t know if the jump was from 23 ish to .08 or .08 to 23 ish. I thought it was the latter… what do you guys think?</p>
<p>the graph question about the concentration of products was the one that kind of looked like a square root graph right?</p>
<p>@yballer I got TF for the one about metal and I put buret for the measurement.
@2015er I believe so. From 0 curved into a constant line basically?</p>
<p>What did you guys put for the question about the change in concentration in a saturated solution?</p>
<p>no change. i believei t was TF?</p>
