A. The components of a homogeneous mixture are chemically combined:
This statement is False. In a homogeneous mixture, the components are not chemically combined; rather, they are mixed together in a way that the individual substances retain their own properties. Examples include saltwater or air, where the components can be separated via physical processes.
B. Homogeneous mixtures have uniform properties:
This statement is True. Homogeneous mixtures exhibit uniform properties throughout the mixture. No matter where you sample the mixture, it will appear the same, meaning it has a consistent composition and appearance. This is a defining characteristic of homogeneous mixtures.
