Well its 2 2NH3--> N2 + 3H2 Just because the nitrogen and the hydrogen are diatomic molecules

I also have a question I need some help with: Selective Oxidation The standard reduction potential for the half-reaction Sn4+ + 2e- Sn2+ is +0.15 V. For a galvanic cell under standard conditions, which of the following cathodic half reactions would produce, at the anode, a spontaneous oxidation of Sn to Sn2+ but not Sn2+ to Sn4+. (a)Sn4+ + 2e- Sn2+ (b)PbSO4 + 2e- Pb + SO42- (c)Fe2+ + 2e- Fe (d)Fe3+ + 3e- Fe (e)H2 + 2e- 2H- (f)2H2O + 2e- H2 + 2OH-

purple rocket..i still dont get it...can you explain a little more detailed if you can

Nitrogen and hydrogen are "diatomic" gases. They exist in nature as two atoms bonded together. They are never found, in nature, as N and H buth rather as N2 and H2. NH3 <==> N2 + H2 (unbalanced) 2Nh3 <==> N2 + 3H2 (balanced)
