<p>puddinggirl, the question asked for experimental observations, and choice D was the right answer b/c it said D) Cu loses 2 e-
and you can't observe that...it's D
Jksbond...i used kaplan too...
i really recommend barrons..lol
kaplan = no</p>
<p>what did you get for the electron configuration one? was it as tricky as other people were saying? I just put p3 orbital.</p>
<p>i dont think they mean observation literally...</p>
<p>and how could the cu dissapear?? all the other choices, which all of u substantiate, are correct. and they all imply the cu stays because the others say like it turns black, or is lighter.</p>
<p>so does anyone have an answer to the electron config. question (about the element in the same group as N)?</p>
<p>i put down p^3...b/c nitrogen is something like 1s^2, 2s^2, 2p^3 or something (forget -<strong>-)...
but then a friend told me that she rechecked that question and foudn that the answer she put- which was also the one ending in p^3- had 4s^2 before it...so it was a trick!!!! -</strong>-</p>
<p>no, i dont remember a 4s being there</p>
<p>it could be a product, not necessarily Cu but maybe CuO. it doesn't say 'Cu is dark' it says 'product is dark'.</p>
<p>but if the question read experimental observation, isn't it taken as literal observation? that's why Cu disappears is an answer choice (you observe that it disappears, doesn't mean it has to..just an experimental observation)</p>
<p>o.... DAMMIT!!</p>
<p>tm2000, are you sure about the 4s not being there? b/c otherwise, this is such a simple question (that's why i was afraid of the trick thing...)</p>
<p>so is the Cu experiment answer D, Cu loses 2 electrons?</p>
<p>for one T/F question</p>
<p>something like d has 4 orbitals BECAUSE it can contain maximum of 8 electrons</p>
<p>I put F,F because d has 5 orbtials which contain 10 electrons</p>
<p>i think that we are totally overthinking these questions. --;</p>
<p>theres the experiment. shiot, u guys are right. i hate myself, i didnt do good on this one</p>
<p>did u all get a T/T without a Ce. i think i did..</p>
<p>^...don't say that :(..it's ok...
it's just one question..
and puddinggirl, you're right...F/F for that one...hehe...
we must overthink! that's how we learn!!</p>
<p>I only got 2 Ce's...um..if you go back to page 9 (or around there) in this thread, i think there was the discussion on Ce's -__-..
i don't even want to think about those..
for some reason, i kept getting FF and TF</p>
<p>there was a good amount of FF's and T/F F/t ones</p>
<p>for that problem...</p>
<p>its F/F cause</p>
<p>the d contains 10 electrons (5 orbitals)</p>
<p>so both wouild be wrong..</p>
<p>right??</p>
<p>disprove me</p>
<p>yea. that was like the easiest one lol.</p>
<p>^..yes both were wrong</p>
<p>Variance, yep, no doubt on that one, it's definitely F, F</p>
