<p>isnt it ttce?</p>
<p>@TypicalAsian, what are you saying the answer is then?</p>
<p>Why would it be CE, the second part said that H2 was less dense than AIR not water. Even if you used Xenon gas, it would be more dense than air, but you can still collect it through water displacement because it’s less dense than water.</p>
<p>but isn’t it at least part of the reason?</p>
<p>I think the key word was air, if they had said less dense than water, then yeah, but they said air, so I don’t think so. Maybe.</p>
<p>Well I put T T CE, but now that I think about it, it would probably make sense if it was only T T</p>
<p>hm i still think its tt ce…oh man,.</p>
<p>i don’t think it’s ce because hydrogen displaces water by pushing it out of the way, and it only does that because water is more dense and sinks, so its density in relation to water matters, but air isn’t in the tube, so i don’t think that would matter. and i think they were probably trying to trip us up by putting air instead of water.</p>
<p>On the only released College Board Chemistry test, this was the curve:</p>
<p>85-800
84-800
83-800
82-800
81-790
80-790
79-780
78-780
77-770
76-770
75-760</p>
<p>So, getting three wrong would result in 790.</p>
<p>which had the most atoms?</p>
<p>more questions pleaaaaaaaaaase</p>
<p>20seconds for 1 mol in 25 degrees. 5seconds for 45? (rate doubles for every 10degrees)</p>
<p>numbers 1 2 3
were A C E?
lol sorry random</p>
<p>
</p>
<p>Wait, wasn’t the question asking which had the least number of atoms?</p>
<p>@nde most atoms
were 1g Ag</p>
<p>Yeah, it was least atoms and the answer was Ag.</p>
<p>5 seconds, since it is halved twice.</p>
<p>i think i remember putting ag (e ?)</p>
<p>20seconds for 1 mol in 25 degrees. 5seconds for 45? (rate doubles for every 10degrees) ?
anyone?</p>
<p>i put 5 seconds (a?)</p>
<p>Yes, it was five seconds.</p>
<p>The released CB test was easier, so the curve for this test (hopefully) will be a little bit more generous.</p>
