Verified step by step guidance

Understand the definition of a homogeneous mixture: A homogeneous mixture is a mixture in which the composition is uniform throughout. This means that the different components are not visibly distinguishable.

Examine each option provided in the list to determine if it fits the definition of a homogeneous mixture.

Consider 'Chicken noodle soup': This is a heterogeneous mixture because you can see and separate the different components like noodles, chicken, and broth.

Consider 'Sand (unfiltered)': This is also a heterogeneous mixture because it consists of different particles that can be seen and separated.

Consider 'Fruit salad': This is a heterogeneous mixture as well, since the different fruits can be seen and separated. 'Seawater (unfiltered)' is typically a homogeneous mixture because the salt is dissolved uniformly in the water, but if it contains visible particles or debris, it may not be homogeneous. 'A cup of black coffee' is a homogeneous mixture because the coffee is uniformly dissolved in the water, making it consistent throughout.
