Which reaction between the given substances produces ammonia under the right conditions?
I. NH₄Cl and Ca(OH)₂
II. NH₄Cl and NaOH
III. NaOH and Ca(OH)₂
- I, II
- II, III
- I, III
- Only III
📝 Detailed explanation
Ammonia is produced when ammonium salts react with strong bases.Reaction I: 2NH₄Cl + Ca(OH)₂ → CaCl₂ + 2H₂O + 2NH₃
Reaction II: NH₄Cl + NaOH → NaCl + H₂O + NH₃
Reaction III does not contain a source of nitrogen.
