Question

what is a solution? a mixture where two fluids separate from one another. a mixture where one substance clumps unevenly into another. a mixture where one substance dissolves evenly into another.

Explanation:

To determine the correct definition of a solution, we analyze each option:

• The first option describes a mixture where fluids separate, which is not a solution (solutions are homogeneous and do not separate).
• The second option describes a substance clumping unevenly, which is a heterogeneous mixture (like a suspension or colloid), not a solution.
• The third option, where one substance dissolves evenly into another, matches the definition of a solution (a homogeneous mixture where the solute dissolves in the solvent uniformly).

Answer:

C. A mixture where one substance dissolves evenly into another. (Note: Assuming the third option is labeled C; if the original labels were different, adjust the identifier. Here, based on the order, the correct option is the third one with the description "A mixture where one substance dissolves evenly into another.")
