An alloy is considered a homogeneous mixture because:
-
A.
it contains two or more phases
-
B.
its components are chemically combined in fixed proportions
-
C.
its components can be separated by filtration
-
D.
it exhibits uniform composition throughout
Correct Answer:
D. it exhibits uniform composition throughout
Explanation:
An alloy is classified as a homogeneous mixture because its components are distributed evenly at a molecular level, resulting in a single phase with a uniform composition throughout the entire sample. Unlike heterogeneous mixtures, which have visible boundaries between different substances, the properties and appearance of an alloy remain consistent regardless of which part is examined. While the individual elements in an alloy retain their chemical identities and are not bonded in fixed ratios like a chemical compound, they are so thoroughly blended that they cannot be separated by simple physical methods like filtration.
