Suspensions, solutions, and colloids share some characteristics, but there are important differences among them. Which option best describes the difference between suspensions, solutions, and colloids? Practice
Select all that apply.

A
A suspension and a colloid are homogeneous, while a solution is heterogeneous.

B
A colloid contains dispersed particles, while the particles in a suspension will settle.

C
A suspension contains visible matter particles, while a solution contains dissolved matter.

The correct statements are B and C.

Further explanation

A pure substance can be an element or compound.

A mixture is a combination of two or more single substances. The properties of the mixture component are not lost / unchanged as in compounds.

The mixture can be divided into a homogeneous mixture if the composition/ ratio of each substance in the mixture is the same and a heterogeneous mixture if the ratio of the composition of the substances is not the same (can be varied) in each place.

Mixtures can also be divided into solutions, suspensions and colloids based mainly on the size of the particles

A. Homogeneous mixture = Solution

Heterogeneous mixture = suspension, and  colloid

B. Colloids and suspensions have particles but colloid particles remain scattered and do not settle, because generally have a charge between the particles

C. Suspended suspension particles are large so they can be seen, while solution particles in the form of a solute dissolve into the solvent, so they are evenly distributed and cannot be seen (too small)

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
