<p>shane are u talking about the hess’s law one…?
the choices were like -85 -35 25 and some others</p>
<p>umm yeahh
it was like
-85 i thinkk</p>
<p>wow 227 is really good
although if i wasnt dumb/checked my work i would have gotten 230 
o well, next year is what matters :)</p>
<p>no the enthalpy one was -35
you just added up the numbers. -60 + 25</p>
<p>where are u from, let me guess new jersey aka home of the genuises</p>
<p>but wasnt it endothermic makign it a gain of heat andthe only + answer was 25 i dunno…</p>
<p>All you had to was apply Hess’s Law.</p>
<p>all you need to do is add the problems together cuz hess’s law as peeps said</p>
<p>hahhaa actually i am living in new jersey currently
but i was born/lived in california for 10 years</p>
<p>noo im like 90% sure it was -85
cause u had to reverse the second one</p>
<p>thought so lol</p>
<p>No, you just added them together as written.</p>
<p>Came out to -35.</p>
<p>was +25 a choice?</p>
<p>so is anyone thinking about cancelling?
i’m probably definitely (lol oxymoron) registering for june just in case
and if my score is good enough, i’ll just take… math I or something useless LOL.</p>
<p>but i know some colleges dont accept score choice…
ugh if only princeton would make their decision, seriously</p>
<p>its not -85.</p>
<p>lol what of new jersey cyanide?</p>
<p>shahe i put 25… but i dont think i did it right</p>
<p>was+25 a choice</p>
<p>and you didn’t have to reverse them</p>
<p>the equations were something like</p>
<p>X (g) -> 2Y + Z dH = 60
X (l) -> X (g) dH = -25</p>
<p>see if you add them, the X (g)'s cancel and you’re left with X(l) -> 2Y + Z which is what they asked for</p>
<p>theres no need for reversing anything.</p>
<p>yea u just add them no reversal necessary…</p>
