Write the balanced chemical equation for the decomposition of sodium azide. If this is a redox reaction, show half reactions and determine if spontaneous. The chemical equation is 2NaN3(s) -> 2Na(s)+3N2(g) right? I am confused on the oxidation states for NaN3... please explain!
On the left side,
Na is +1
Each N in NaN3 is -1/3
On the right side, Na is zero, N in N2 is zero.
