New to the forums here. If anyone needs me I’ll be over in the corner hyperventilating into a paper bag because of this exam. -1 on the exam, here I come!
@glasshours: Thanks! Could you also help me on #49 pls?
@ambitious98 the anode/cathode switches from a galvanic to electrolytic so the substance that has the more positive SRP in the galvanic would get reduced (cathode) in an galvanic and oxidized in an electrolytic (anode) so yes
What would you be reviewing now? Id think at this point you more or less understand most topics or you dont have time to understand
How do you all feel about caffeine consumption before this exam?
@JuicyMango - What are you still reviewing? I went through the 2013 and 2014 tests yesterday and today, then I’ve just been answering questions on here since this morning, which has been a surprisingly effective method of studying 
@Mathman97 usually yes except for dispersion forces because all molecules have them and in the case of oil it doesn’t really make a significant case for dissolving
any good last minute online comprehensive study guides?
I just watched dragonball z episodes all day yesterday…
I’m reviewing the 2013 and 2014 exam questions, which has been going really slow for me because I don’t seem to be getting anything.

1st is kinda short/to the point
2nd is longer but more in-depth/covers some stuff u don’t need to know but covers the stuff you do very well
Isnt the one with the higher srp reduced in galvanic anyways?
@JuicyMango - 49: the first thing I noticed was that butane doesn’t have hydrogen intermolecular forces, so that eliminates C and D right away, because stronger IMFs = higher boiling points. Larger molecules also have higher boiling points; 1-propanol is larger than acetone.
@Xurian - I need caffeine or I can’t function haha (went into the SAT IIs yesterday without caffeine…worst decision of my life)
@Mathman97 Yes so which ever half reaction has the higher SRP will get reduced and the other will get oxidized
so its not different between galvanic/electrolysis?
@Xurian strongly recommend doing whatever your norm is. If you usually have caffeine, don’t go without. If you usually don’t, then don’t
Also, for the heat=mc(delta t) equation, what mass in exact do we use in the equation? i always forget!
Is the 2014 exam people have been talking about the one with the hydrogen bonds on 59 and a kp problem on 60?
^no thats the practice test
@shough101 - I read somewhere on here that we don’t need to know that equation, but just in case, you use the mass of the thing being heated/cooled (e.g. if water is being heated, convert mL to g and use that mass).
@glasshours: I thought acetone also lacks hydrogen bonds? Doesn’t a hydrogen have to be bonded to either F, O, or N?
