22. How many grams of ammonia can be produced when 20.0 g of Mg3N2 and 20.0 g of H20 are reacted? What is the limíting reagent? How many grams of unreacted material will remain? Mg3N2 + H20---> Mg(OH)2 + NH3

It will fall off and tip over. 

Idon't hope someone you

What record? the question is incomplete

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
