Another question sorry, but when the shape of a molecule is bent is it aways 104.5 or can it sometimes be 120?
If there's three pairs of electrons on central atom with one of them being a lone pair, then it's bent with 120 degrees. If there's four pairs of electrons on the central atom with two being lone pairs, then it's bent with 104.5 degrees.

Nope. Sometimes "extra" electron density can cancel out can cancel out extra repulsion from a lone pair. Sulfur dioxide, for example, has a bond angle of 120 degrees and is bent.

At times like this i don't understand chemistry at all...
just from reading the pre-release and having a guess i would say that in the morning from rush hour lots of nitrous oxides are released from the combustion of the engine fuel...this then sticks around in the atmosphere so sunlight acts on it and photo dissociates? or maybe just travels to the stratosphere because thats where the high energy uv is. or it might react with ground level ozone (someone clarify?) then at night there are less cars on the road and no sunlight so concentrations decrease....and going on this same principle, in summer the sun is hotter and in winter its not and the general temperature is colder....who knows if this is actually correct
EDIT: maybe its nh3 + OH makes NH2 and water? if NH2 can be a radical...and if not then i guess its a termination reaction? thats my only other idea...
