Ethanamine, a basic amine, reacts with HCl to form its salt, ethylammonium chloride (CH₃CH₂NH₃A+ ClA−).
Ref: NCERT Class 12 Chemistry > Chapter 13: Amines > Topic: Chemical Reactions - Alkylation, Acylation and Electrophilic Substitution
Reaction: 2Al + 6HCl → 2AlCl₃ + 3H₂. Moles of H₂ = 5.6/22.4 = 0.25 mol. 3 mol H₂ from 2 mol Al; 0.25 mol from (2/3)×0.25 ≈ 0.1667 mol Al. Mass = 0.1667 × 27 ≈ 4.5 g.

Reaction: Na₂CO₃ + 2 HCl → 2 NaCl + CO₂ + H₂O. Moles of Na₂CO₃ = 10.6/106 = 0.1 mol. 1 mol Na₂CO₃ produces 2 mol NaCl; 0.1 mol produces 0.2 mol. Mass = 0.2 × 58.5 = 11.7 g.
