Vedclass · Answer

(C) The law of definite proportions states that a given chemical compound always contains its component elements in a fixed ratio by mass. Nitrogen forms multiple oxides with oxygen (e.g.,$N_2O, NO, N_2O_3, NO_2, N_2O_5$). Since nitrogen exhibits variable valency,it forms different compounds with oxygen,meaning the mass ratio of nitrogen to oxygen is not fixed for the general term 'nitrogen oxide'. Therefore,the law of definite proportions is not applicable to the generic term 'nitrogen oxide' as it does not refer to a single specific compound.
