Question

when salt is dissolved in water, the resulting solution is a... homogeneous mixture element heterogeneous mixture compound

Explanation:

A homogeneous mixture has a uniform composition throughout. When salt (sodium chloride) dissolves in water, the salt ions disperse evenly in the water. There are no visible boundaries or separate phases. An element is a pure substance made of only one type of atom. A heterogeneous mixture has visibly different parts. A compound is a pure substance formed by chemical bonding of two or more elements. Since salt - water solution has a uniform composition, it is a homogeneous mixture.

Answer:

homogeneous mixture
