in a galvanic cell,
-anode is the metal that undergoes oxidation
-cathode is the metal that undergoes reduction</p>
<p>hahah I’m too slow</p>
<p>For writing the equations:
If, say, there are 3 products but you only get two of them correctly, do you still get 1/2 product points, or none at all?</p>
<p>Ugh, I didn’t read the ‘nonvolatile’ part.</p>
<p>Remember, the colligative properties when solute is added are boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure.</p>
<p>In the PR book they wrote AN OX and RED CAT for anode-oxidation and reduction-cathode to help memorize</p>
<p>My teacher told us that An Ox jumped over a Red Cat.</p>
<p>chickenonrice. anions are oxidized, cations reduced.</p>
<p>in order to find E in galvanic cells do u do cathode minus anode or what?</p>
<p>Guys what calculator can you bring in the FRQ part?</p>
<p>Cathode minus anode.</p>
<p>K what about this mc ?
Gaseous cyclobutene undergoes a first-order reaction to form gaseous butadiene. At a particular temp, the partial pressure of cyclobutene in the reaction vessel drops to 1/8 its original value in 124 seconds. What is the 1/2 for this reaction at this temp?
a) 15.5 sec
b) 31 sec
c) 41.3 sec
d) 62 sec
e) 124 sec</p>
<p>i got b but the answer is c</p>
<p>lol theradtomato i haven’t even done orgo yetD:</p>
<p>my next questions is on this:<a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>Supporting Students from Day One to Exam Day – AP Central | College Board;
<p>what the hell do u for part d of the question with the galvanic cell?</p>
<p>i know u use log of k is equal to n(E)/.0592.</p>
<p>but how do i determine n ?</p>
<p>are there any really specific things we need to know?</p>
<p>Hi for that MC I did it using half life thingie
1–> 1/2 –> 1/4 –> 1/8
3 half lives passed so it’s 124/3 = 41.3 = half life :)</p>
<p>lol theeboy3, i think alot of ap chem is based on specific things. what do u consider specific things?</p>
<p>also how do you find f) on <a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>Supporting Students from Day One to Exam Day – AP Central | College Board; ? question 2</p>

<p>Like having to know what an amalgam is, or having to know Fe3+ is gold, Fe2+ is faint red?</p>
<p>Gah I can’t decide if I want to bring my TI 84 or just a scientific calc. You can store info on the TI 84 calc right so wouldn’t that be cheating?</p>
