<p>i think filer paper was twice</p>
<p>no im pretty sure its just once, salt would be distilled, ink would be chromotagraphied, the metal would be magentized and the solid would be filtered</p>
<p>really do u remember the question for the metal one i dunt think i ever chose magnet</p>
<p>it was like how to seperate iron and sulfur, that definately wouldnt of been filtered</p>
<p>r u sure...............anyone else help us out?</p>
<p>it was definately a metal and sulfur. i remember looking up to see if it was a metal or not</p>
<p>hey elsmurf do u remeber any of the T/F quesitons, besides the neon and H2S one,?</p>
<p>a T/F question or sth like it: </p>
<p>I: NaCl has a lower freezing point than CxH22O11
II: NaCl has a less molar mass than CxH22O11</p>
<p>the metal was iron...so i chose magnet.
ink...chromatography
NaCl and water...may have messed up on this one
silver nitrate in solution of something nitrate...may have messed up on this one, too</p>
<p>wasn't there a 5th one???</p>
<p>ali_liu: i said T/T for that one, no CE.</p>
<p>hey for the freezing temp one, what did you guys put. I put salt had lower freezing temp.</p>
<p>umm.. for that question in assertion reason type:
halogens are good oxidizing agents
because
samples of halogens contain O2..
what did u guys do?
i marked it true, fals buut im not sure...</p>
<p>fr the freezing pt true false, i think it was a CE as depression in freezing pt is inversely variable with molecular mass</p>
<p>It was T/F. F2, for example, is a really great oxidizing agent.</p>
<p>Freezing, I put true/true. Freezing is a colligative property meaning it doesn't have anything to do with the actual molar mass -- it's all about how many particles (ions, molecules, atoms, etc.) are in solution. Glucose doesn't dissociate; salt does. Hence, the freezing point of salt is -1.86 degrees celsius that of glucose.</p>
<p>altf4, for the silver nitrate, i wrote filteration.. as silver nitrate is solid and it was in a solution... for the NaCl in water one i wrote distillation.. what do u think?</p>
<p>Silver nitrate is a solution isn't it? But since it said that it would react with something chloride, and AgCl is definitely a precipitate, I put filtration.</p>
<p>Yeah, thats what I put too.</p>

<p>yeah...T/T/no CE</p>

</p>
<p>that's probably what it was...</p>
<p>For the halogen question, what was being tested is whether oxidation is directly related to oxygen CONTENT, which it is not...because certain halogens are pure, kept in containers, and then allowed to be ox-agents to other compounds</p>
<p>i messed up on ^ that one too, i think i said F/F, answer should be T/F...</p>
<p>oh great, i KNOW already at least 6 wrong >< gar.</p>
<p>eh i think i still got like 10-15 wrong, hopefully no more than that. in retrospect, i should have omitted some "unsures"....grrr</p>
<p>same here!! gar.</p>
