online quiz 3
eeyur chiobu nv post answers on blog :(
害我得不到满分!
anyway, here're the answers for the latest online chem quiz :)
the polar molecule that absorbs microwave energy : NF3 (because it is polar)
*MgO isnt the answer because it is not polar (it is a freaking ionic compound, i kena scam)
variation in bond angles of water and ammonia is due to : number of lone electron pairs
change in bond angle from SO2 to SO3 : decrease from 120 to 107 (according to notes)
species containing the smallest bond angle: BrF5 (< or = to 90)
junan~
did you have a GOOD friday and HAPPY easter sunday? :P
