Don't worry! Please don't. Most of the people that say it was "easy" never end up getting what they expected; you might have scored very well :wink:

be optimistic and also, this paper is only 20% of our overall grade!

Depends on how high your grades where, if you got 2 high A's and a high D then you probably would get an A overall

To be honest the exam was pretty good. It was way easier than January 2014... What did you guys find so difficult about it?

Why can't the enthalpy change of decomposition NH4CL be measured directly by experiment

1.(Sr)2+ + (CO3)2- = SrCO3
2.16.26g
3.This answer has 2 parts:
1st part: Z is not a carboxylic acid since it doesnt turn litmus blue paper red
2nd part: Z is not a primary or secondary alcohol since it didnt turn KMnO4
colorless so it is a tertiary alcohol
