Is the decomposition of lead(ii)nitrate a redox reaction?
Equation with O.S. underneath
2Pb(NO3)2 => 2PbO + 4NO2 + O2
+2 -1 +2-2 +4-2 0
I got all the o.s. but I am still confused as to whether or not this makes it a redox reaction. Do the individual elements in the nitrate ion count?

1. Sorry, I didn't know it would post like that! I'll clear up the O.S.
Pb = +2
NO3 = -1

Pb = +2
O = -2
N = +4
O = -2
O2 = 0
