[anabourdais]

I have been working at this for about two days now and haven't really gotten any further. Unfortunately my teacher is away but last time he checked it over he said I was 'almost there' so a few extra nudges in the right direction would be appreciated!

I'm trying to write out the reaction mechanism for the formation of acid rain from atmospheric nitrogen. I know the general equations to go through but when it comes to showing the movement of electrons with 'curly arrows' I get stuck!

so, this is what I have so far:

1. O + N?N ? N=O + N

2. N + O=O ? O + N=O

3. 2N=O + O=O ? 2O=N=O

4. N=O + O=O=O ? O=O + O=N=O

5. O=N=O + O-H ? H=O=N=O
                                     ¦¦
                                      O

Any help is appreciated!

start by drawing the reactants and products in full lewis structures to see where the electrons are, then you'll probably notice the electron "movements" soon enough.

what's lewis structures??

Wiki even explains it

ok i have never been told that they are called lewis structures. anyway i worked it all out. even without advice.
