<p>It's O2 or H2, because HCl is soluable in water, so you can't use it for that.</p>
<p>what about the one asking for the compound not found in its elemental state as stated in the answers? answers were Au, S, O2, N2, Na.. i put S</p>
<p>Oh...I put Au for that question</p>
<p>what about the one that was brittle, could conduct electricity when melted, etc.?</p>
<p>that was the ionic bond one</p>
<p>I put Na because I figured Na would probably react with other things.</p>
<p>yeah...I should've put Na...that definitely makes sense</p>
<p>^same (..)</p>
<p>i said o2 and h2 could be collected. don't know about hcl
so what was the answer to the radioactive particle electron one? was it I and II because i know i didn't choose III (for 1/3 mass)</p>
<p>Yeah, I put 1 and 2...but I can't remember what the other one was (the one that wasn't radioactive electron)</p>
<p>Hmmm... I should have put Na, but I put S because sulfur generally occurs as S8...</p>
<p>I put Na because it's so reactive</p>
<p>Hmm guys what did u put then for the one about water boiling at higher temps (t/f question). I put T/T something about air pressure was the 2nd one.</p>
<p>i omitted it. =[</p>
<p>it was F/T</p>
<p>It waid water boiled at a higher temp at higher altitudes (it boils lower)</p>
<p>No it said water boiled at a LOWER temperatue at higher altitudes. Trust me it said LOWER. But I am worrying if air pressure is higher at higher altitudes..</p>
<p>It was t/f. Air pressure is lower at higher altitudes.</p>
<p>Thirding the T/F. Air pressure is not higher at higher altitudes.</p>
<p>Oh well that sucks >.<. Did you guys get 65 grams for something? Did you get .03 moles of pbi2?</p>
<p>I put true/ false becacue water boils at lowerr temperatures at high altitudes and false because the atmosphere is not higherr at higher altitudes</p>
