Understand the definition of a homogeneous mixture: A homogeneous mixture is a mixture that has a uniform composition and appearance throughout. The components are evenly distributed and not easily distinguishable.
Analyze each option to determine if it is homogeneous or heterogeneous: A heterogeneous mixture has a non-uniform composition with distinct, easily identifiable components.
Consider 'Chicken noodle soup': This is a heterogeneous mixture because you can see and separate the chicken, noodles, and broth.
Consider 'A cup of black coffee': This is a homogeneous mixture because it has a uniform composition throughout, with no visible separation of components.
Consider 'Sand (unfiltered)', 'Fruit salad', and 'Seawater (unfiltered)': These are heterogeneous mixtures because they contain distinct, visible components that are not uniformly distributed.
