Explanation:

To answer these questions, we can refer to the provided website (http://www.ducksters.com/science/chemistry/chemical_mixtures.php) and recall basic concepts about suspensions and colloids:

Suspensions (heterogeneous)

• A suspension is a mixture between a solid and a liquid. In this case the solid particles are large enough to be seen. The particles and the liquid are mixed up so that the particles are dispersed throughout the liquid. They are not dissolved in the liquid. A key characteristic of a suspension is that the particles will settle out if left alone.
• An example of a suspension is a mixture of sand and water. When mixed up, the sand will be suspended in the water. If left alone, the sand will settle to the bottom of the container.

Colloids (heterogeneous)

• A colloid is a mixture where very small particles are dispersed throughout another substance. They appear very similar to solutions, but the particles are larger than those in a solution rather than dissolved. The difference between a colloid and a suspension is the size of the particles and their ability to stay suspended; in a colloid, the particles are small enough that they will stay suspended or float.
• An example of a colloid is milk (or fog, whipped cream, etc.). Milk is a mixture of fat globules and protein particles in water.

These answers are based on the definitions and properties of suspensions and colloids in chemistry. If you need more detailed or specific information, you can visit the provided website for further exploration.
