<p>It’s definitely trigonal pyramidal. If you draw a Lewis diagram, you’ll see that N has an extra pair of electrons sticking out. In fact, NH3 is a super duper Lewis base. Hope that helps. :)</p>
<p>I havent reviewed any chem since the AP test, and I’m pretty sure I got a 5 on that (Just barely though). How much should I study for this exam?</p>
<p>Thanks. I just noticed that yangmaster’s last relationship analysis question has a wrong answer. It should be FT because NH3 isn’t tetrahedral.</p>
<p>Isn’t the electron pair geometry of NH3 tetrahedral since it has 3 bonding pairs and 1 lone pair? It’s not talking about the actual molecular geometry</p>
<p>Good luck everyone! May the curve ever be in our favor!</p>
<p>^Yeah nsojori09 is onto something. He’s right! It is tetrahedral.</p>
<p>…</p>
<p>Guys that was a very very easy exam.</p>
<p>I wish i was on this thread ealier,i wud hav left the question i skipped</p>
<p>What was the answer to the glass question? I put SiO2</p>
<p>SiO2 is right.</p>
<p>Very tough, much harder than any practice exam I’d ever taken.</p>
<p>is kinetic energy and kinetic speed the same thing?</p>
<p>How many CE’s did you guys get? I got either four or five</p>
<p>The test was easy compared to the practice tests. I think I did well!</p>
<p>^and no speed and kinetic energy aren’t the same</p>
<p>Three CEs, right?</p>
<p>3 CE’s sounds about right to me, either that or 4. What was the question about Lab Safety Procedures, was the answer fire polishing?! Also, for the reaction with 100 mL of 1 Molar NaOH that would liberalize the most heat, was it 1 Mole of HCl?</p>
<p>That test was ok, but there were obviously those handful of questions where I really didn’t know what to pick. Nonetheless, I’m happy with getting a 700+ which isn’t too hard to get hopefully.</p>
<p>I got fire polishing for lab safety, and I had 4 CEs I remember 3 of them were back to back and there was a fourth one a few questions later. Imo those questions were a lot easier than on practice tests.</p>
