● By heating ammonium chloride with slaked lime:
2NH4Cl+Ca(OH)2→2NH3↑+CaCl2+2H2O
2NH_4Cl + Ca(OH)_2
ightarrow 2NH_3 + CaCl_2 + 2H_2O

Detailed Explanation

In this reaction, ammonium chloride (NH₄Cl) is heated together with slaked lime (calcium hydroxide, Ca(OH)₂). During the reaction, ammonium chloride decomposes and produces ammonia gas (NH₃), calcium chloride (CaCl₂), and water (H₂O). The equation represents that for every two parts of ammonium chloride used, one part of slaked lime is required, resulting in two volumes of ammonia gas released.

Examples & Analogies

Imagine baking cookies where ammonium chloride is like flour and slaked lime is like baking powder. When you combine them under heat (mix and bake), you get delicious cookies (ammonia gas) along with leftover ingredients (calcium chloride and water) that are not needed for the final treat.

↳ 2NH3↑ + CaCl2 + 2H2O

Detailed Explanation

The reaction produces three important products: ammonia gas (NH₃), calcium chloride (CaCl₂), and water (H₂O). The ammonia gas is the desired product in this preparation, which can be collected from the reaction. This gas is used in various applications including agriculture as fertilizer. The remaining calcium chloride and water can also be used in other chemical processes or as by-products.

Examples & Analogies

Think about when you brew your favorite tea. The tea leaves (ammonia) that come out of the brewing process are what you want, but you also have leftover water (which can be reused for watering plants) and tea leaves (calcium chloride, potential use in composting).
