Question

a solution is an example of a (an)_____
a. pure substance
b. element
c. compound
d. homogeneous mixture
e. heterogeneous mixture

Explanation:

To solve this, we analyze each option:

• Option a: A pure substance has a fixed composition (element or compound), but a solution has multiple components, so not pure.
• Option b: An element is a pure substance with one type of atom; a solution has multiple substances, so no.
• Option c: A compound is a pure substance with a fixed ratio of elements; a solution is a mixture, so no.
• Option d: A homogeneous mixture has uniform composition (like a solution, where solute dissolves in solvent uniformly).
• Option e: A heterogeneous mixture has non - uniform composition (e.g., sand in water), while solutions are uniform.

Answer:

d. homogeneous mixture
