Answer :
Final answer:
Vinegar is heterogeneous, salt water is homogeneous, and salad dressing is homogeneous. A homogeneous mixture is a mixture in which the components that make it up are uniformly distributed throughout the mixture.
Explanation:
The correct option is Option 3: Vinegar - Heterogeneous, Salt water - Homogeneous, Salad dressing - Homogeneous. The given substances can be classified as either homogeneous or heterogeneous mixtures based on the uniformity of their composition.A heterogeneous mixture is a mixture in which the components are not uniformly distributed, and can often be visibly distinguished.
A homogeneous mixture has uniform composition, meaning the components are evenly distributed and not easily distinguishable. Salt water is an example of a homogeneous mixture as the salt is dissolved evenly throughout the water.A heterogeneous mixture has non-uniform composition, meaning the components are not evenly distributed and can be easily distinguished. Vinegar and salad dressing are both examples of heterogeneous mixtures as they contain visible components that are not evenly distributed, such as oil and vinegar droplets in salad dressing.

Option 2: Vinegar - Homogeneous, Salt water - Homogeneous, Salad dressing - Heterogeneous.
Homogeneous Mixture: This type of mixture has the same uniform appearance and composition throughout. Examples include solutions where one substance is completely dissolved in another, such as salt water.
Heterogeneous Mixture: This type of mixture does not have a uniform composition and the different components can be seen or easily separated. Examples include mixtures where the different parts are visibly separate, like salad dressing.
Now, let's classify the given substances:
Vinegar: Vinegar is a homogeneous mixture. It is a mixture of acetic acid and water, and its composition is uniform throughout.
Salt Water: Salt water is a homogeneous mixture as well. When salt is dissolved in water, it forms a solution where the salt is evenly distributed throughout the water.
Salad Dressing: Salad dressing, such as oil and vinegar dressing, is a heterogeneous mixture. The oil and vinegar do not mix uniformly and you can see the separate components.
