(a) The chemical equation to prepare ammonia from ammonium chloride is

2NH₄Cl + Ca(OH)₂ → CaCl₂ + 2H₂O + 2NH₃↑
(b) Chemical equations to identify Cu⁺² & Ag⁺ ions with the application of NH³:

AgCl + 2NH₄OH(excess) → Ag(NH₃)₂ Cl + H₂O

CuSO₄ + 2NH₄OH → Cu(OH)₂↓ + (NH₄)₂ SO₄

Cu (OH)₂ + 4NH₄OH (excess) → [Cu(NH₃)₄] (OH)₂ + 4H₂O
(c) Flowchart for the manufacture of ammonia by Haber process is as shown.
N₂ + 3H₂ ⇌ 2NH₃
