diagram with red, black, blue particles blank blank

Explanation:

Step1: Identify the components

The diagram shows different types of molecules/particles. In the row we need to analyze, there are multiple types of molecules (different structures: some with red and white, some with blue and white, some with red and black). So it's a mixture.

Step2: Determine homogeneity

Since the different types of molecules are evenly distributed (no visible separation), it's a homogeneous mixture.

Answer:

mixture, homogeneous
