Sand is a mixture and rarely is only one compound.
Yes, colloid is a type of solution where particles are suspended in a medium, such as water. Creek water after heavy rain may contain suspended particles like dirt, sand, and organic matter, making it a colloid solution.
No, because the sand particles do not dissolve and in time will settle at the bottom making it a suspension.
Sand in water is a suspension..

Chlorine is a gas at room temperature and pressure, not a solution or colloid. It can be dissolved in water to form a solution known as chlorine water, which is used as a disinfectant.
No, it is a salt. I water it forms a solution.

Yes, mouthwash is a colloid. It is a liquid mixture containing suspended particles that do not settle out.
A homogeneous solution is a solution without interfaces (a particle with visible sides/something floating around that is not completely saturated) that is not opaque. A heterogeneous solution is a solution with interfaces. A colloid is a solution that has no interfaces but is opaque. Saltwater (with the salt completely dissolved) is a homogeneous solution; water with sand mixed in is heterogeneous because it will eventually separate and the sand has interfaces: and skim milk is a colloid because it is opaque but has no interfaces.
