The gas given off when NH₄Cl is heated with an alkali is

Answer Details

When NH₄Cl is heated with an alkali, it undergoes a chemical reaction known as the Hofmann's degradation reaction, which produces ammonia gas (NH₃). The reaction is represented as: NH₄Cl + NaOH → NaCl + H₂O + NH₃ Therefore, the correct answer is NH₃.
