Final answer:
Iced tea is a homogeneous mixture, while apple pie, orange juice, and vegetable soup are heterogeneous mixtures. A sample with various components and different properties across different regions is also classified as a heterogeneous mixture.
Step-by-step explanation:
The answer to the first part of the question, which asks about identifying a homogeneous mixture from the given options, is that iced tea is a homogeneous mixture. It is also known as a solution because it exhibits a uniform composition throughout. On the other hand, apple pie, orange juice with pulp, and vegetable soup show variations in composition and appearance, making them heterogeneous mixtures.
Regarding the second part, based on the observations that the sample contains various components and different regions of the sample have different properties, the students will classify the matter as a heterogeneous mixture.
