Question

Write the chemical equation for the reaction between two gases to produce a solid substance.

WBBSE Class X Physical Science Inorganic Chemistry 01 Mark 2026

Answer

The reaction between ammonia gas (NH₃) and hydrogen chloride gas (HCl) produces solid ammonium chloride (NH₄Cl).

NH₃(g) + HCl(g) → NH₄Cl(s)

The product ammonium chloride is formed as a white solid.
