Which will settle out if allowed to sit on a table? suspension colloid solution compound a suspension a colloid a solution a com
liubo4ka [24]

Answer is suspension.

Lets define all options.

<h3>Suspension:</h3>

In suspension the solute does not dissolve in liquid. When placed on table for some time, it will settle down at the bottom of the beaker. We can separate particles of solute easily from solvent through filtration.

<h3>Colloid:</h3>

In colloid particles of solute does not dissolve in liquid neither it is settle down. It floats through the solvent. It cannot be separated by filtration.

<h3>Solution:</h3>

In solution the particles of solute dissolve in to the solvent. We cannot identify them as separate. We cannot separate them by filtration. Salt and water solution is an example of it. Evaporation is the technique that is required to separate them.

<h3>Compound:</h3>

In compound, the two elements combine to form a new thing. Resultant/ compound have new or different properties other than its ingredients.

Now, the question was which of the following allow to settle out when sit on a table, so the answer is suspension. Suspension allows the particles to settle out when sit on a tables for some time.
