Final answer:
A homogeneous mixture is uniform in composition throughout, meaning it appears and behaves as a single substance. Examples include air, salt water, and sports drinks, and such mixtures are also known as solutions.
Step-by-step explanation:
A homogeneous mixture is one that: B. is uniform in composition. This means that the substance acts as a single entity with a composition that is uniform throughout. Examples of homogeneous mixtures include air, salt water, and sports drinks, where the different substances that make up the mixture are not visibly distinguishable and are spread evenly throughout.
When we consider the properties of a homogeneous mixture, also known as a solution, we see that each portion of the mixture is identical in composition to any other portion. Whether it's a drop of a sports drink or a flask of salt water, each part has the same ratio of components, ensuring uniform taste and properties throughout. Even though the specific ratios of components like sugar in a sports drink can vary, it still retains its character as a homogeneous mixture as long as the mixture itself remains uniform.
