Which sample is a homogeneous mixture?

a) naci(s)
b) nacl(aq)
c) nacl(g)
d) nacl(ℓ)

NaCl(aq) is a homogeneous mixture.

An aqueous sodium chloride is a homogeneous mixture because NaCl completely dissolves in water, thus giving a single visible phase.

Further ExplanationMixture  A mixture is a substance that is made up of two or more substances that are not chemically combined and in fixed proportions.  A mixture may have several varying physical properties.There are two types of mixture:Homogeneous mixtures  These are mixtures with a similar uniform appearance and composition throughout. Examples are, steel, air, salt water, etc.Homogeneous mixtures may either be, a colloid or a solution.Solutions  Solutions are types of homogeneous mixtures containing two or more substances in a single phase.Solutions contains, a solute which is the substance that dissolves in the other substance, and a solvent which is the substances that dissolves the solute.For example, in a salt solution, water is the solvent and salt is the solute.Colloid  A colloid is a homogeneous solution that has an intermediate size particles between a suspension and a solution. Examples of colloids are fog and milk.  Heterogeneous mixturesThis is a type of mixture that contain different substances or two or more phases of matter.The components of heterogeneous mixtures are not uniform such that different samples of the mixture are not identical to each other.  Examples of heterogeneous mixtures are; blood, soil, Gravel, etc.Suspension  It is a type of heterogeneous mixture made of larger particles that are visible and normally settles when the mixture is undisturbed.Examples include, tomato juice, fine sand, etc.
