<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>
