<p>i said something about after incubation in dark…</p>
<p>@mh12325
I put the m-t thing</p>
<p>what about the one that said why it wouldn’t matter if you put an extra weight on both, or something.</p>
<p>i think it said that it would matter about the dry weight because its per gram</p>
<p>@sp it’s because it was measured per gram</p>
<p>Damn, I put that there was heat because R was 0. I could have sworn that was the case :/</p>
<p>its not cuz they wiegh afterwards its cuz they weigh the thing by gram so its like all proportioned out by weight not per tube or something</p>
<p>thanks…that’s what i put, but wasn’t sure</p>
<p>what about the 88k one? did anyone get that for an answer?</p>
<p>^ yep, 88k :)</p>
<p>Yes I put 88K after looking at the key at the bottom of one of the figures.</p>
<p>88k one? i dont remember, what was the ?
aahh…nevermind</p>
<p>i remember a number like 5.09 or 6.09 also</p>
<p>^ 5.09, yep.</p>
<p>awesome, what about these:
12% hydrogen or h20 was lost in the reaction
carbon dioxide was formed from the decomposition of caco3</p>
<p>^I put both of those.</p>
<p>guys the answer to the second to last one in the conflicting viewpoints one was D…(student 1 was wrong; he said if U goes up, so does K [which is obviously untrue due to the law of conservation of energy], but the question was ACCORDING to him) so according to him, when height is decreased (thus, U is decreased), K is decreased as well (so, the answer was K is less, because U is less [or something like that])</p>
<p>(where U = potential energy, K = kinetic energy)</p>
<p>HOPING FOR A 36; i think i might’ve actually done it! :)</p>
<p>this was the first test where i actually finished early for science/reading!!! SO glad the fighting scientists one was on physics!!!</p>
<p>oh and #39 was the m-k thing because it had the same R (0.02) although the melting point was 94-96 whereas the other one that had the exact same specified melting point of 93-95 had an R that was way out of the correct range. ACT probably just wanted to test your knowledge of the fact that sometimes temperatures can be off like this (by 1 degree) due to error.</p>
<p>what was one of the last questions where it asked which of the 3 students was right? I think i put student 1 and 2… anyone else?</p>
<p>jahamba- I put 60% h20 because I compared the mass of CACO3 to that of hydrated wtv it was called</p>
