Question

apply it
distinguish in each sample, create a model that shows the difference between a
pure substance, a heterogeneous mixture, and a homogeneous mixture. use shapes
or symbols to represent different types of matter.
pure substance heterogeneous mixture homogeneous mixture

Explanation:

• Pure Substance: Represented by a single type of shape (e.g., all circles). A pure substance has a uniform and definite composition.
• Heterogeneous Mixture: Represented by different shapes that are not evenly distributed (e.g., some circles and some squares grouped in patches). The components are not uniformly mixed, and you can visually distinguish different parts.
• Homogeneous Mixture: Represented by different shapes that are evenly distributed (e.g., circles and squares mixed uniformly). The composition is uniform throughout, and you cannot visually distinguish the different components.

Answer:

• For the pure substance circle: Fill it with one type of symbol (e.g., all small circles inside).
• For the heterogeneous mixture circle: Divide it into sections and fill each section with a different symbol (e.g., one - third with triangles, one - third with stars, one - third with squares).
• For the homogeneous mixture circle: Mix different symbols uniformly (e.g., small circles and small squares distributed evenly throughout the circle).
