Quizplus · Accepted Answer

Gaseous mixtures are typically homogeneous, meaning that the composition is uniform throughout. This is because the molecules or atoms in a gas mixture are free to move and mix with one another, leading to a uniform distribution of components. Choice A is incorrect because gaseous mixtures can contain both molecules and atoms. Choice B is incorrect because some gaseous mixtures can be homogeneous. Choice C is incorrect because gaseous mixtures can contain both isolated atoms and molecules.
