| Almonds- that one stumped me for a bit but you're right- only it wasn't for water, it was the nitric acide one. Good luck! | |

| Can someone please go through FR #8 with me? It seemed most people went for #7 -- a choice I respect -- but seriously, I'm sure somebody here knows something about #8. | |

| All the questions are up on AP Central (apcentral.collegeboard.com)
AgNO3 --> Ag+ + NO3-
1. Is delta-G (Gibbs Fr. En.) positive or negative? Explain why.
2. Is delta-S (Entropy) + or -? Explain
3. Is delta-H + or -?
Is this consistent with your answers in parts 1 and 2? Explain | |

| About the pro-base, are you talking about a Bronsted-Lowry base? Pro(ton acceptor) base? | |

| There was nothing about it being a bronsted, arrhenius, or lewis base. Don't worry about it. :-( :-( :-( It may just be the opposite of pro-acide...and we all know what THAT is. ;-) | |

| Student, I dont think its that nobody got #8 as much as #7 was just ridiculously (really ridiculously) easy and did that.  | |

Delta S will be positive
Delta H will be postive | |
