Study the flow chart given and give balanced equations to represent the reactions A, B and C:
Mg3N2→ANH3⇄CBNH4Cl\text{Mg}_3\text{N}_2 \xrightarrow{\text{A}} \text{NH}_3 \xtofrom[\text{C}]{\text{B}} \text{NH}_4\text{Cl}Mg3N2ANH3BCNH4Cl
A : Mg3N2 + 6H2O ⟶ 3Mg(OH)2 + 2NH3 [g]
B : NH3 + HCl ⟶ NH4Cl
C: NH4Cl + NaOH ⟶ NaCl + H2O + NH3 [g]
