How does a heterogeneous mixture differ from a homogeneous mixture? How are they similar?

Solution:

Mixtures are defined as systems containing two or more components that can be separated by physical means. When components mix and blend in such a manner that all regions are the same, the system is homogeneous; soft drinks, sugar water, gasoline, brass, and sterling silver are common examples of such mixtures. Most mixtures in the environment and in our experience are not homogeneous. Instead, mixtures such as deposits of rocks and minerals, river water, blood, and fruit salad are heterogeneous. The mixtures are alike in that physical methods, rather than chemical methods, can be used to separate the components.
