ammonia gas reacts with copper (ii) oxide at high temperatures to produce elemental nitrogen, copper metal, and water vapor. Assume that 36.2g ammonia reacts with 180.8 g copper ii oxide.

(balanced equation: 2 NH4 (ammonium) (g) + 4 CuO (copper ii oxide) ==> N2 (nitrogen gas) (g) + 4 Cu (copper metal) (s) + 4 H2O (water vapor) (g)

Which species is the limiting reagent?

Please justify your answer! thank you!
