• # question_answer To which of the following gaseous mixtures is Dalton's law not applicable A)                 $Ne+He+S{{O}_{2}}$   B)                 $N{{H}_{3}}+HCl+HBr$ C)                 ${{O}_{2}}+{{N}_{2}}+C{{O}_{2}}$          D)                 ${{N}_{2}}+{{H}_{2}}+{{O}_{2}}$

$N{{H}_{3}}$ and $HCl$ & $HBr$ is a reacting gas mixture to produce $N{{H}_{4}}Cl\And N{{H}_{4}}Br$ so Dalton's law is not applicable.
