<p>a few of these T/F/CE questions can go either way.</p>
<p>However a person has mentioned that on the test it is specifically stated that the diatomic molecule is X2 type.</p>
<p>Oh ok, Thanks Kscnoko.</p>
<p>N2<FCl<KO </p>
<p>Was that answer choice A?</p>
<p>Yeah, I think that was A</p>
<p>i don't remember the exact question, but the answer was either 2,400 or 4,400.
which on was it?</p>
<p>& then the one with the calculating the density of the substance given the water displacement. what was the answer to that one?</p>
<p>if i omitted about 4 & got like 10 wrong, how do you think my score will turn out to be?</p>
<p>4,400 is the answer</p>
<p>how about the question with which one will bethe best to obseve a precipitate in?</p>
<p>hey guys, umm which books did you use to prepare for this test?? like PR, barrons etc. im taking it next yr and it sounds pathetic but i want to know which i should buy -_-; also, how do you think you did with which ever book you used? im hoping to get like 750+</p>
<p>princeton review has oddly close answers to the test... i've heard of multiple exams where there were multiple questions that appeared verbatim.
this year's bio had no less than 8 tricky questions in the second practice.
check with upperclassmen with underclassmen siblings. they usually don't write in them so their younger bro/sis can use it later. ask to borrow it. also, i strongly recommend the official guide. buy all books used at half.com for a pretty big savings; most aren't written in, and the books barely change each year besides the person on the cover.</p>
<p>in summary, PR>CB>others.
um, and an AP book (PR--"used" of course) will seriously help with tricky problems and the "next level" of learning. take tests in june after you finish the class. preferably take the AP also so you have double reason to study</p>
<p>the classification section kinda scared me</p>
<p>yellow suffocating gas ---chlorine
dense metal w/ low melting point---bromine
always positive oxidation states ---lead
yellow solid high melting point ----sulfur</p>
<p>is that right?</p>
<p>bromine is a liquid.
i put that the dense metal one was lead.</p>
<p>its actually dense metal-lead
and everything else of your list is correct</p>
<p>RJacob's post "It said all diatomic molecules are nonpolar BECAUSE they are all linear"</p>
<p>TT</p>
<p>Shouldn't it be TT CE? cuz the fact that the molecules are linear makes the molecules nonpolar along with the fact that they have same electronegative values.</p>
<p>does someone mind answering the questions that were left unanswered above?</p>
<p>thanks. :]</p>
<p>i put TTCE for that one too.</p>
<p>^^ that is the test tube</p>
<p>I got 2,400.
(m)(cp)(∆T)
(10g)(4J/ºC)(60ºC)=2400.</p>
<p>I think...</p>
<p>+1 to dense metal being lead.</p>
<p>I put TT for the linear one.</p>
