Question

laboratory preparation of ammonia
with balanced stoichiometric equation ​

Answer 1

Answer:

laboratory preparation of amonia (NH³)

⇩⇩⇩⇩⇩⇩⇩⇩⇩⇩⇩

The amonia is generally prepared in laboratory by gently heating

of Slaked lime ( calcium hydroxide ) Ca(OH) ² and amonium chloride NH⁴Cl.

Equation is ⇩

2NH⁴Cl + Ca(OH) ²→ CaCl²+ 2H²O+2NH³

FOR THIS AMONIUM CHLORIDE AND CALCIUM HYDROXIDE REQUIRED 2:3 RATIO BY WEIGHT

And it can also be produced. in INDUSTRY by heating N² and O² at 500°c under 200atm in the presence of Fe catalist

The reaction is ⇩

Fe

N²(g) +O²(g) → NH³(g)

200atm; 500°c

Through Haber's process.

Answer 2

ANSWER

Lab preparation of ammonia:

2NH4Cl+Ca(OH)2---) CaCl2+2H2O+2NH3

The ammonia gas is dried by passing through a drying tower containing lumps of quicklime (CaO).

Hope it helps ☺️
