Which of the following is an example of homogeneous mixture? b. a typical soil sample

c. a glass of orange juice
d. a bottle of vinegar

depends on what A is.

To identify which of the options is an example of a homogeneous mixture, we need to understand what a homogeneous mixture is. A homogeneous mixture is a combination of two or more substances that have been thoroughly mixed and have a uniform composition throughout, meaning that you cannot distinguish the individual components with the naked eye.

Let's analyze the options one by one:

a. A typical soil sample: A soil sample is a heterogeneous mixture because it consists of various components like rocks, minerals, organic matter, and water. These components are not uniformly mixed throughout the soil, so this option is not an example of a homogeneous mixture.

b. A glass of orange juice: Orange juice is a homogeneous mixture because when freshly squeezed, the juice, water, and pulp are thoroughly mixed, resulting in a uniform composition. As a result, this option is an example of a homogeneous mixture.

c. A bottle of vinegar: Vinegar is a homogeneous mixture as well. It is made by mixing acetic acid and water, resulting in a uniform solution throughout the bottle. Hence, this option is also an example of a homogeneous mixture.

Therefore, the correct answer is both option b. a glass of orange juice and option d. a bottle of vinegar.
