<p>@browndynamite F2 is the hardest to oxidize, and yes Ne was the one that did not react</p>
<p>@lazamataz burets are used for titration and it was asking what would be most useful is measuring 23.whatever volume of the solution… which is a graduated cylinder</p>
<p>@d0texe Burets can be used for measuring volumes to the hundredths, which is what the question was asking for.</p>
<p>Don’t worry, at least you didn’t say friggin’ volumetric flask. Stupid me. >.></p>
<p>what about this pressure asking N + O?
the answer choices were like
a. half of oxygen
b. twice of oxygen
c. triple of oxygen
blah ?!</p>
<p>i totally ommitted lab related questions because im sure i get them wrong.
i hope i get 800 with 3 omit + 2/3 wrong </p>
<p>@nicoleryoo I think it was triple, because the number of moles was 25% O2 and so it was 75% N2, and since the ratio of moles is the same as the ratio of partial pressures, (3/4)/(1/4) = 3</p>
<p>@browndynamite I got the same thing.</p>
<p>me too</p>
<p>If you get a 75/85 what score can you expect to get? a 700?</p>
<p>^ I estimate somewhere around 740-760. This is with the lenient curve of six questions missed is still an 800.</p>
<p>@capitalamerica It’s definitely F2. Think about it this way: being oxidized means losing electrons. If F2, were to lose electrons, you’d have F+ ions. Knowing that fluorine is the most electronegative element helps in realizing that that’d take a ton of energy.</p>
<p>@burning00 3x10^23 question was CO2. You have 22 grams of CO2, which is half of a mole.</p>
<p>Alright in the middle of doing some practice for the AP exam tomorrow, I realized that I may have done all of my math wrong when multiplying the decimals to find moles when given molarity and liters… Do you remember if there were trick answers where the decimals were off but the numbers were the same?! I’m really scared right now ._.</p>
<p>@burning00 oxidation means removing electrons from atom/molecule; therefore, it’s most difficult to remove an electron from F2 from the otherss</p>
<p>Does anyone remember any questions from the begining? like the matching with the types of reactions any others?</p>
<p>Fluorine is known to be the Best Oxidizing agent. That means it gets reduced Most easily. Hence no way it can get oxidized!</p>
<p>@Morgolfaznot The only one I remember that was questionable was the polymerization since I didn’t study organic chemical reactions. I’m pretty sure that was the combination of the two organic molecules though. Anyone else?</p>
<p>@morgolfaz @capitalamerica I think the other two were hydration, which I said was the one that made a hydrate, and redox.</p>
<p>@capitalamerica It was the combo of the 2 organic molecules + H2O, thats called a condensation polymerization reaction, you’re right</p>
<p>What was the one where they were asking about molar energy or something?</p>
<p>the polymerization reaction was the one that had n-(CxHy) - > CxnHyn or something like that</p>
<p>Polymer’s are generally described as ‘n’ chains, so whenever you are looking for a polymer, keep your eye out for the variable ‘n’ in a formula.</p>
