Question

5 multiple choice 3 points when you pour salt into water and mix it until all the salt dissolves what kind of homogeneous mixture is it? salt water is a pure substance heterogenous mixture slime solution

Explanation:

A pure substance has a fixed composition, and salt - water is a combination of salt and water, so it's not a pure substance. A heterogeneous mixture has visibly different parts, but salt - water is uniform, so it's not that. Slime is a different kind of material altogether. A solution is a homogeneous mixture where one substance (solute, here salt) is dissolved in another (solvent, here water).
