Investigating Redox Reactions: Zinc Oxidation

[Soley101]

I'm trying to find out what type of reaction this is.
a drop of water is added to a small pile of chemicals in a dish, after a few seconds, a blue flame and smoke is produced.

NH4NO3 reacts to form (with chlorine as catalyst) N2O and water

the experiment is called oxidation of zinc, so another equation is Zn and NH4NO3 react to form ZnO and water.

this is definitely a redox reaction right? but is there not a decompostition reaction first that allows the zinc to oxidize? so really, this reaction is oxidation reduction, catlyzed, and decomposition?

Well your reaction is catalyzed and decomposed but that's not what the reaction is. The reaction you have already stated as the oxidation of Zn or a redox reaction.
