<p>shorter bond angles*</p>
<p>Lone pairs do repel each other to a greater degree, however electron groups always repel EACH OTHER (though to different degrees), and therefore have MUTUAL repulsion.</p>
<p>i said TF because I thought mutual repulsion=linear/nonpolar/symmetrical. But im not sure? Everyone said it was TTCE so I assumed I was wrong lol. I if you search mutual repulsion electron geometry or anything related nothing comes up in google anywhere so its hard to tell…</p>
<p>urghhh</p>
<p>Edit: I hate barron’s for making me associate mutual repulsion with linear and octahedral.</p>
<p>There was a true false about adding neutrons and increasing atomic radius, but I believe that was a TF.</p>
<p>I also remember more than 6 TTCEs. Maybe there were 6 in the second row, but there were maybe 2-3 more in the first row.</p>
<p>ah, i assumed by mutual they meant they repelled to the same degree, but now that i see it from everyone elses viewpoint i guess im wrong… oh well haha</p>
<p>I know. j999 I feel like there is an argument for both which is what I hate about those types of questions. And I think I remember that one yunu578, or I remember one which was like “all atoms of the same element have the same number of neutrons” and then “all atoms of the same element have the same atomic number” or something… and it was FT.
does anyone remember that?</p>
<p>I remember that one… it was “all atoms of the same element have the same mass” and “atoms of the same element have the same number of protons”</p>
<p>^ Oh yeah that was another one. It said all atoms of the same element have the same mass, and thats false because of isotopes. Then it said all atoms of the same element have the same number of protons.</p>
<p>I think the one I am thinking about is the one where it said as the atomic number increases in a family the radius goes up. Then it said adding neutrons to the nucleus makes the radius goes up. TF</p>
<p>Anyone remember the one where the answer was 0.1g of NaOH?</p>
<p>On the water one, did it say that the ionization AT 25C IS 10^-14 OR that it is 10^-14 period? Did it have at 25C? Just asking. This might be from another practice test I took…</p>
<p>Ohh I<3pi thats what I was thinking of.</p>
<p>And I said TF for the one you are referring to yunu578 but I don’t remember the adding neutrons part lol, just the atomic number increasing makes the radius increase in a family part…</p>
<p>and jenkster im pretty sure it said “at 25C the ionization constant is only 1.0e-14”
which confused me for a second for some reason, but then I got it.</p>
<p>ok thanks.</p>
<p>anyone remember the answer to the one that was like which of the following contains 3.22 x10^23 atoms</p>
<p>
</p>
<p>Wait a minute. The first one specifically said that Neon emits light when an electric current is passed through because excited atoms go from a higher to lower energy state. I’m not sure, but the atom part made me think that it was false. Electrons go from one energy level to another. And, I’m absolutely sure that it said atom not electrons about this cause it was the last question I checked and I spent 5 min on it at the end. </p>
<p>The fluorine gas one makes me wonder, though. Just because a substance has weak intermolecular forces doesn’t mean that it is gas. I put TT for that one. Some of these are debatable, which is what makes them such as stupid format.</p>
<p>Idk about the first. I was pretty sure it said electrons, but I’m not really a reliable source because I sped through it. But the only reason a substance is a gas at room temperature is because it has a very low boiling point and what determine boiling point is the strength of IMFs</p>
<p>The first one, I’m absolutely sure it said atoms, not electrons. I perused that question for 5 minutes, so I basically memorized it.</p>
<p>I’m pretty sure the second part was worded in a way where it was true, even if it did mention atoms.</p>
<p>For IMFs, think of it this way. If water didn’t exhibit hydrogen bonding, it would be a gas at STP.</p>
<p>Yeah, I realize that now. I got the F2 one wrong, but I’m sure about the other one. Oh well, move on folks.</p>
<p>I got 8 CE’s total and only one T,T w/o a CE. As for remembering more questions, my photographic memory is good but not that great. I already posted like 20 questions on page 3.</p>
<p>Also, I only remember getting like 2 or 3 F’s for Statement I. What about you guys?</p>
<p>:( tux you have scared me about the neon one. Anyway, bumb about the answer for “which of the following has 3.22x10^23 atoms?” q?</p>
<p>bestyanks - i also remember getting a weird amount of T’s for statement 1… not sure number but I remember being a little put off…</p>
<p>I don’t remember the answer to that one.</p>
<p>Bestyanks930, I remember some more TTCEs as well, but unfortunately, I don’t remember the actual questions.</p>
