<p>Cu is metallic and well electrical conductivity</p>
<p>yes crucible and NH4Br and i don’t remember the Cu question…but yea that’s obviously true</p>
<p>does anyone remeber any questions?</p>
<p>H2O’s boiling point is higher than H2S …because H2O’s bonding is stronger than H2S /… (TTCE?)</p>
<p>yea, H2O has hydrogen bonds, i think i put TTCE as well</p>
<p>WHAT WAS the kinetic molecular theory… question? </p>
<p>was it kind of Collid each molecules and also collid to the wall… something like this…</p>
<p>other answers …constant speed, one direction…etc.</p>
<p>i put collide with each other and walls…holy crap you have a good memory</p>
<p>on part A… if “CO2” put in to water, then does it make weakly acid solution???.. in the other answers … C2H5OH… something HCl and NaOH…</p>
<p>that’s correct, it’s CO2 because when added to water, it becomes HCO3, which is a weak acid</p>
<p>and also in kinetic theory… TF Question…</p>
<p>um… if temperature is increased then something something something … i think i put T in this statement. … and molecular engergy is greater than activation energy…something something… i think I put T also…so CE … i GOT…right???</p>
<p>I don’t remember exact element … and it is might be TF question…</p>
<p>in akali metal family, as atomic number is increased reactivity is increased…</p>
<p>yea i put TTCE also for the kinetic question…wow this is really reassuring that we’re getting the same answers…have u taken AP chem…i got a 5 on AP, but I thought the SAT II was harder lol!</p>
<p>for the alkali metal question, I put that as atomic # increases for alkali’s, reactivity increases (b/c atomic radius gets bigger as valence shell # gets larger)</p>
<p>no… actually i am taking AP course, and i will take… but… I hope scale is going to be generous… b/c i omitted a lot…</p>
<p>Oh… there was some thing “saturated question” If NaCl puts in to water continuously then… something concentration is increase?? i think i put that kinna sentence.</p>
<p>o… and Why is rusting iron caused entropy to increase? I thought alcohol boiling was the answer ( liquid → gas :vapor)… i don’t know… :(</p>
<p>eh, one of the answer choices was liquid–>gas? are u sure about that…b/c if it was, then that’s probably the answer…but then again, rusting is spontaneous…so…</p>
<p>there was something … number of electrons??? is different???</p>
<p>oh… did you guys put any answer on the part A something about Nuclear fission or fusion???</p>
<p>yea # electrons different</p>
<p>and i don’t remember which one i put betw. fusion and fission…prolly fission</p>
<p>I think the reason it was rusting was because the questions specified it was a chemical change where is boiling isnt.</p>
