A colloidal suspension is a type of heterogeneous mixture where particles are evenly dispersed throughout a medium like a liquid or gas, preventing settling. This is due to the small size of the particles, which remain suspended through constant movement and collisions with the particles of the medium.
Centrifugation is a separation technique that relies on the components of a mixture settling into layers based on their densities. By spinning the mixture at high speeds, the heavier components move to the bottom, while the lighter components stay at the top, allowing for easy separation.
An example of a homogeneous mixture is salt water, where the salt is evenly dissolved throughout the water without forming separate layers or settling at the bottom.
Sandy water is a mixture, not a compound. It consists of water (H2O) as the solvent and sand particles as the solute, which are mixed together physically and can be separated through filtration or settling.
No, silicon and water do not form a mechanical mixture. A mechanical mixture is a physical combination of substances in which the individual components retain their original properties and can be separated by physical means. In the case of silicon and water, they do not mix together to form a homogeneous mixture and can be easily separated by filtration or settling.
"Easily mixed" refers to a situation where different substances are thoroughly combined to create a uniform mixture without any visible separation or settling. This uniformity ensures that the components are evenly distributed throughout the mixture.
Suspension
A liquid mixture in which particles can be seen and easily separated by settling or filtration is a suspension.
Separation by density
It is a suspension.
It is a suspension.
No, brass is not a heterogeneous mixture; it is a homogeneous alloy made primarily of copper and zinc. In brass, the metals are melted and combined to form a uniform material with consistent properties throughout. This means that its composition and appearance are uniform, distinguishing it from heterogeneous mixtures, where different components can be easily identified and separated.

A mixture in which the layers are too small to be seen, such as whipped cream, is called a colloid. In a colloid, tiny particles are dispersed throughout a continuous medium, resulting in a uniform appearance without settling. This type of mixture exhibits properties of both solutions and suspensions, but the particles remain suspended rather than settling out.
Yes, a solution can settle over time. This settling process occurs as the particles in the solution separate and sediment to the bottom due to gravity. To prevent settling, the solution can be continuously stirred or shaken.
Crystal settling occurs when solid particles (crystals) settle at the bottom of a liquid due to gravity. As the crystals are denser than the surrounding liquid, they gradually sink to the bottom. Factors such as particle size, density, and viscosity of the liquid can influence the rate of crystal settling.
