Classify the following as either an element, a compound, a homogeneous mixture, or a heterogeneous mixture.
a. homogeneous mixture
b. element
c. heterogeneous mixture
d. compound

salt dissolved in water
muddy water
sodium fluoride (naf)
silver (ag)

Salt issolved in water: homogeneous mixture

muddy water : heterogeneous mixture

Sodium fluoride = compound

Silver = element

Explanation:

Step 1:

A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.

A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture.

A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition.

An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number. Elements cannot be broken down using chemical reactions.

Salt dissolved in water = Salt is soluble in water, which would give a homogeneous mixture

Muddy water = Muddy water, on the other hand is a heterogeneous mixture because mud can settle, leaving the mixture with much less mud at the top of the bucket than the bottom.

Sodium floride =  a compound made of 2 elements: Sodium and fluoride

Silver = An element, it can be found on the period table.

ill try to . no promises tho.

explanation:

the answer is definitely c.
