(http://uploads.tapatalk-cdn.com/20180115/b301e9deb99c1af1fbb9c64c95ee40b1.jpg)I thought the 3rd equation is meant to be N2O3 (for the N2O5)
How did they get the five though?

Also, does it matter if you write 2AlN=Al2 +N2 and 2AlN=2Al+N2?

The reaction should be balanced as 2HNO3 --> N2O5 + H2O. What is happening is that when two HNO3 molecules collide, each loses a hydrogen and one of them loses an oxygen to form water. N2O5 is what you have leftover.

I'm not really too sure what your saying here. Are you asking if writing 2Al forming is the same as Al2? If so, that would be seen as two different products forming. Al2 would imply some sort of diatomic molecule made of 2 Al atoms, whereas Al would imply aluminium metal forming.
