An example of a homogeneous mixture is
a. noodle soup.
b. stainless steel.
c. oxygen.
d. distilled water.

b. stainless steel.

Explanation:

Heterogeneous mixtures  : It is a mixture that has non-uniform composition throughout the solution and the particle size or shapes are also different. There is a physical boundary between the dispersed phase and dispersion medium.

Homogeneous mixtures  : It is a mixture that has uniform composition throughout the solution and the particle size or shapes are not different.  There is no physical boundary between the dispersed phase and dispersion medium.

1. Noodle soup is heterogeneous as the components are physically distinct.

2. Stainless steel is  homogeneous as the components are not physically distinct.

3. Oxygen is an element.

4. Distilled water is a compound as it is free of other materials and ions.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
