Answer

Brief Explanations:

The provided clues are definitions related to mixtures, solutions, and the process of dissolving, commonly encountered in chemistry. Each answer corresponds to the definition given.

Across [3] A solute is a substance that dissolves in a solvent to form a solution. [5] Disappear means to cease to be visible. [8] Dissolve refers to the process where a solute breaks down into tiny particles and mixes evenly with a solvent. [11] Separate means to divide or move apart components of a mixture. [12] Clear describes something transparent and not cloudy.

Down [1] Pure describes a substance not mixed with any other substances. [2] A solvent is a substance that dissolves a solute, resulting in a solution. [4] Opaque means not able to be seen through; not transparent. [6] A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase sometime after their introduction. [7] A solution is a homogeneous mixture formed when a substance dissolves in another. [9] Saturate means to cause (a substance) to combine with, dissolve, or absorb the greatest possible quantity of another substance. The first part "To move apart" can refer to the dispersion of particles during dissolution until saturation. [10] A mixture is a substance made by combining two or more pure substances in such a way that no chemical reaction occurs, and they can be separated.

Answer:
