Write the reaction equation: N2-NH3-NH4Cl-NH3

1) N2 + 3H2 = 2NH3 (when nitrogen interacts with hydrogen, ammonia is formed);

2) NH3 + HCl = NH4Cl (when ammonia reacts with hydrochloric acid, ammonium chloride is formed);

3) NH4Cl + KOH = KCl + NH3 + H2O (when ammonium chloride interacts with potassium hydroxide, potassium chloride, ammonia and water are formed).
