salt water is a solution, since it dose not scatter light, and appears as one layer.
None of these. Water is a compound, which is a pure substance.
No it is a compound.
Colloid has larger particles compared to solution, but smaller than suspension. Therefore, of the three options listed (compound, colloid, suspension), a compound mixture typically has the smallest particles.
Sand is a mixture and rarely is only one compound.
Blood is a colloid. A colloid is a mixture in which one substance is finely dispersed in another substance, but not actually dissolved. Blood consists of cells and platelets suspended in plasma, making it a colloid.
None of these. Water is a compound, which is a pure substance.
No it is a compound.
A colloid is not a single compound; it is a mixture with properties between those of a solution and fine suspension.
A colloid. It is not a solution - that would be clear because one compound is dissolved by the other. It is not a suspension - a suspension is solid particles mixed with a liquid
It is a suspension.
Sand in water is a suspension..
Colloid has larger particles compared to solution, but smaller than suspension. Therefore, of the three options listed (compound, colloid, suspension), a compound mixture typically has the smallest particles.

Sand is a mixture and rarely is only one compound.
HCl is a solution, not a colloid or suspension. A solution is a homogeneous mixture where one substance dissolves in another, as is the case with HCl dissolved in water. Colloids are mixtures with particles dispersed throughout, while suspensions have particles that can settle out over time.
Blood is a colloid. A colloid is a mixture in which one substance is finely dispersed in another substance, but not actually dissolved. Blood consists of cells and platelets suspended in plasma, making it a colloid.
Salt is a compound because it is composed of sodium and chloride ions that are chemically bonded together in a fixed ratio. It is not an element, suspension, heterogeneous mixture, homogeneous mixture, or colloid.
