Last day to win £100 of Amazon vouchers - don't miss out! Take our quick survey to enter 24-10-2016
1. KN2O(sub-script3) -> KNO(2) + 2O(2)
Numbers in brackets are the little ones that go one the bottom right corner
2. As far as I can tell yes.
Just in case, here's how:
KN2O(3) So, 2x3 = 6 O, there's 1 K and 1 N

In KNO(2) + 2O(2), first part is 1x2 = 2 O, second part 2x2 = 4, all equals 6 O, there's 1 K and 1 N.

You've got it covered!
