Question

a homogeneous mixture of two or more substances is called a(n) ________.
colloid
compound
aggregation
solution

Explanation:

To solve this, we analyze each option:

• A colloid is a heterogeneous mixture with dispersed particles.
• A compound is a pure substance made of two or more elements chemically bonded, not a mixture.
• Aggregation refers to the clustering of particles, not a homogeneous mixture of substances.
• A solution is defined as a homogeneous mixture of two or more substances (solute dissolved in solvent).

Answer:

D. solution (assuming the options are labeled A to D with D being solution; if the original options had labels like the last option as solution, the correct one is the option with "solution" text, e.g., if the last option is labeled as D, then D. solution)
