Pb(NO3)2 ==> PbO + NO2 + O2 ... decomposition reaction
Not sure how to show the way to balance it. I used a combination of intuition and trial and error to get
2Pb(NO3)2 ==> 2PbO + 4NO2 + O2
I first balanced the nitrogens and then tried balancing the oxygens by putting 2 in front of Pb(NO3)2. But that messed up the oxygens, so I put a 4 in front of the NO2 and that sort of took care of both the nitrogens and the oxygens.

Thanks a lot.03/14/22
