<p>the question asked: are all diatomics linear? and the answer is yes (True). and i’m fairly certain it was CE.</p>

22

<p>For the diatomics question i put CE also</p>

23

<p>yeah i put ce for that one too</p>

24

<p>^All diatomics are linear, but that doesn’t prove that they are nonpolar. I felt that they needed to add a line saying that the atoms have the same EN, and thus the diatomic mc’s are nonpolar. Then again, I don’t know what the CB expects us to deduce.</p>

25

<p>well the curve will prolly be good seeing as how an 800 is like a 95th or 96th percentile.</p>

26

<p>If the second part is a partial reason of why the first part is true, then are you supposed to put CE or not? I hate that section…</p>

27

<p>and what about that question where it gave like 22.4 l of h2 and 02 and we needed to find moles of h2</p>

28

<p>God I’m taking it in June. Nervous wreck.</p>

29

<p>@harvard76, 22.4L = 1 mol of gas at STP.
Since O2 was .5 mol, H2 had to be .5 mol as well.</p>

30

<p>ok i have a question
if I think I did not do well on the test, should I cancel it?
I’m not sure but probably 680~720 I guess.
Why do some people talk about cancellation
can’t i just send my best score to college?</p>

31

<p>What did you put for the questions where the HCl was dropped into the water?</p>

32

<p>whats the curve for chem</p>

33

<p>that was T T CE…HCl is strong acid ==> sort of like electrolyte so it can conduct electricity.</p>

34

<p>it depends. of the two blue book tests ive seen one had a 81/85 as an 800 while another had 77/85 as an 800.</p>

35

<p>I also put T T CE for that one</p>

36

<p>^^ same</p>

<p>are there guessing penalties for the sat II’s? </p>

<p>I don’t really remember, but I think i had T T CE for the diatomic/linear question</p>

37

<p>ok good thats what I had.</p>

<p>For the question:</p>

<p>X2 is diatomic. X2 is linear. </p>

<p>I only had T, T, because some linear molecules are polar (H-Cl)</p>

38

<p>In total I had about 3 T T and 5 T T CEs (roughly). Also, I had two pairs of two TTCE’s in a row.</p>

39

<p>^ <em>high-five</em> I had the same answer. This gives me hope haha</p>

<p>Edit: to post 37</p>

40

<p>yea there was a question like that on the USNCO</p>
