Which sample of matter is a mixture<br> (1) Br2(l)<br> (2) K(s)<br> (3) KBr(s)<br> (4)KBr(aq)
SOVA2 [1]

Answer:

(4)KBr(aq)

Explanation:

A mixture is an impure substance made up of two or more substances that are joined together. Their composition is indefinite and not easily represented by a simple chemical formula.

KBr_{aq} is a mixture because it made up of an aqueous solution of KBr. This suggests that the substance KBr is placed inside water.

Here, we have two states of matter which is the solid and the liquid coming together.

As with both mixtures, they can be separated by physical means, KBr aqueous solution can also be done this way.
