Understand the definition of a homogeneous mixture: it is a mixture that has a uniform composition and appearance throughout, meaning you cannot distinguish the different components visually.
Understand the definition of a heterogeneous mixture: it is a mixture where the different components are not uniformly distributed and can be visually distinguished.
Analyze the example of cereal in milk: the cereal pieces and the milk are separate and can be seen as distinct parts, indicating multiple phases.
Since the cereal and milk are not uniformly mixed and can be visually distinguished, this mixture is heterogeneous, not homogeneous.
Therefore, cereal in milk is not a homogeneous mixture because its components are visibly separate and do not form a single uniform phase.
